Professor Eiichi Yamaguchi is the author of "FUKUSHIMA Report', posted here in Sept. 2013
Tonight (Dec. 10, 2014), three Japanese researchers, Professor Isamu Akasaki, Professor Hiroshi Amano, and Professor Shuji Nakamura are to be jointly awarded the Nobel Prize in Physics 2014 "for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources". Congratulations! -- I am very happy to repost Professor Yamaguchi's paper here now, with which we can learn how the Nobel Prize awarded LED innovation was achieved and how we would be able to contribute to future innovations.
TRIZ Forum: Conference Report (30) Personal Report of The 10th TRIZ Symposium in Japan, 2014 （Sept. 11-12, 2014, Tokyo） (Nov. 27, 2014)
Toru Nakagawa (Osaka Gakuinn University), Nov. 24, 2014.
The 10th Japan TRIZ Symposium 2014 was held last September by Japan TRIZ Society. Being late to my regret, I am writing here my Personal Report for introducing you the event and all the presentations briefly. I think it important for us Japanese TRIZ community to inform you, TRIZ people in the world, about the activities and advancements of TRIZ in Japan.
The Symposium for 2 days had 135 participants in total (mostly from industries, and some from academia; 36% participated for the first time; from overseas: 2 invited speakers + about 3(?) participants). Invited talks: Keynote lecture by Anatoly Guin, Special Invited lecture by Shin Taguchi, and Tutorial 1. 27 Contributed presentation (including 22 oral + 5 poster presentations (including 1 from overseas)). The Symposium was organized well, obtained high-level presentations, and had increased number of participants, all showing its big success. The aspect that the contributions from overseas to presentations and participations are quite small need to be improved.
For all the presentations, slides are projected in Japanese and in English in parallel.. (The Program Committee supported the translation of most presentations into English by using machine translation software. However, the English versions need to be brushhed up further.) Japan TRIZ Society has recently posted the invited talks and 5 award-winning contributed presentations openly in their Official Web site, while all other contributed presntations in the Members-only pages.
For applying TRIZ, a number of industries have suuccessfully adapted TRIZ tools and processes so as to correspond the differences in purposes, characteristics, and fields of the problems and to match with the levels, orientations, available time, etc. of users. They also request external consultants to guide them using TRIZ tools suitable for and effective in their needs and situations. Similarly for the integral use of other methods (e.g., QFD, Taguchi method, Kepner-Tregoe method, etc.), they start using them by smoothly linking the essential parts of them. Apparently TRIZ people in Japan are increasingly interested in applying TRIZ to the problems in software, non-technology, and social fields. There are also many trials to make the TRIZ tools easy to understand and effective to use. In these many aspects, we can say that Japanese industries are advancing TRIZ usage and achieving results in the real jobs.
A vivid report was givien by a national college of technology (i.e., a school for year 15-20-22 students), but almost no report on TRIZ educaion in unversities.
Even though "innovation" is the top-level fashonable keyword in Japan and in the world, we still have not succeeded in introducing TRIZ into national policy and projects, industrial top managements, universities and academia, etc. This is the most important problem for us TRIZ community. We should think and work harder.
TRIZ Forum: Letters from Readers （Aug. - Nov., 2014）(Nov. 27,2014) Index page of "Letters from Readers"
English page
I received an inquirely about the situations and possibiities of publishing Japanese Editions of TRIZ books. Mr. A. Shmonov have sent me several times so far on his work of "Computers can invent independently", but I cannot follow it yet. The four "Entrance pages" are evaluated highly. On the 16th Anniversary of "TRIZ Home Page in Japan", many people sent me messages of congratulations and encouragements. I deeply thank you all.Japanese page
The publication of "TRIZ practices and Benefits" book series are appreciated by several readers. Many readers highly evaluated the four Entrance Pages, in their reader-friendly and easy-access nature to many articles strored in the present site. Mr. T. Maekawa introduced 'What is TRIZ?' to about 300 people in the Tokyo-Yokohama region of Japan QC Association in his News Letter. Several readers communicated me to have started learning TRIZ with the articles in "TRIZ Home Page in Japan".
CrePS/TRIZ/USIT Paper: General Methodology of Creative Problem Solving & Task Achieving (CrePS): Reorganizing Various Application Cases and Their Methods in the ‘Six-Box Scheme’ (Nov. 7, 2014)
Toru Nakagawa (Osaka Gakuin University), (A) Japan TRIZ Society, 10th TRIZ Symposium in Japan, Sept. 11-12, 2014, at Waseda Univ., Tokyo; (B) Japan Creativity Society, 36th Annual Conference, Oct. 25-26, 2014, SANNO Institute of Management, Tokyo; (C) European TRIZ Association (ETRIA), 14th World TRIZ Future Conference 2014, Oct. 29-31, 2014, EPFL, Lausanne, Switzerland
In September and late October, I presented three papers on the CrePS mehtodology at three TRIZ-related conferences mentioned above, with the same title and with some adjustment depending on the audiences and timing. My main message is: "We can establish the General methodology CrePS on the basis of TRIZ/USIT research by reorganizing a wide variety of problem solving methods in the 'Six-Box Scheme'". The on-going research activities for developing CrePS are: (1) To make course materials of CrePS case studies. We should just use case studies already published. (2) To understand different methods (including TRIZ) and to describe them in the framework of CrePS. (3) To relate CrePS to various activities in the 'Real world'. (4) To categorize various purposes of CrePS application, and to recommend concise CrePS processes for each category. (5) To proliferate the vision of CrePS. -- I wish you to share this vision and collaborate together!

On the 16th Anniversary of "TRIZ Home Page in Japan": Toru Nakagawa (Nov. 7, 2014)
This Web site "TRIZ Home Page in Japan" celebrates its 16th Anniversary on Nov. 1 together with readers in Japan and over the world. This site is to promote the understanding and real usage of TRIZ by openly publishing information and communications related to TRIZ on a not-for-profit basis. Though I have been operating this site as a volunteer, this site is not a personal site but a public forum to be composed of the contributions by readers, as you see already. Most pages are published in Japanese and in English in parallel for the purpose of mutual understanding and collaboration between Japanese and overseas TRIZ learners/practitioners. I envisage that Pubic Web Sites built in different TRIZ Communities will form A Global TRIZ Community with much reduced language barriers
Editorial: 'General Index' page has been reorganized and divided into 4 pages (Sept. 25, 2014) (Oct. 17, 2014)

Announcement: Publication Announcement of the Japanese Edition: Umakant Mishra's "Treasury of Inventive Ideas for Information Technology & Software - Classified with TRIZ Inventive Principles" (Aug. 29, 2014)
Authored by Umakant Mishra, Japanese translation by Toru Nakagawa (Supervising translator), Yoshihisa Konishi, Toru Shonai, Masatoshi Hotta, and Takuo Maeda, Published by the CrePS Institute, Kashiwa, Chiba, Japan, on Aug. 25, 2014.

Please see the page of the SeriesThis book is principally dedicated to many people involved in IT and software, as engineers, researchers, PC users, etc. The author collected about 3000 cases of IT/SW solutions from US patents and other technical sources, and interpreted the essence of their ideas to solve the individual problems, and classified the cases with the viewpoints of the essence of ideas by use of TRIZ 40 Principles. In each of 40 chapters, meaning of a Principle is explained first, and then benefits and application situations come, and finally various application cases of IT/SW technology/techniques are described in groups to clarify how the solution ideas may be generated from the Principle. Though the 40 Principles in TRIZ were established in the era of 1960s when the computers and software were not yet developed well, they have been found to very well explain or support the ideas of many inventive cases in the field of IT and software. Mishra's book is a wonderful demonstration of turning a huge complex accumulation of technical knowledge into a treasury of essence of ideas.

Announcement: Publication Announcement of the Japanese Edition: Larry Ball's "Hierarchical TRIZ Algorithms -- Illustrated Course Material from Novices to Experts" (Jun. 30, 2014)
Authored by Larry Ball, Japanese translation by Toshio Takahara and Toru Nakagawa, Published by the CrePS Institute, Kashiwa, Chiba, Japan, on Jun. 30, 2014.
Printed Edition: Soft cover, B5 size, 208 pages, full color, 4200 yen + tax, Print-on-Demand at DLmarket site.

The main body is the 160-page course materials posted in the "TRIZ Home Page in Japan" in 2006-2007 in Japanese translation
This is an excellent textbook of modernized TRIZ. The author advocates that the decisions in the product development process should follow the logical pre-post relationships. The principal stages should be: Business and market needs => What system does => Identify pivotal functions => Idealize functional components => Idealize attributes of functional components. These stages form the hierarchy of decisions, and hence a consistent flow of procedures. During the processes of idealizing the functions and attributes, there appear various problems and contradictions, for which TRIZ tools can be used effectively. Especially, the author demonstrates a large number of viewpoints of separation of Physical Contradictions, beyond classical TRIZ tools. There are full of illustrations of small cases for explaining the concepts/processes. The textbook is easy to understand and enjoyable for beginners, and yet is challenging for experts.

TRIZ Introduction Paper: "Hierarchical TRIZ Algorithms" and Its Further Development (Jun. 30, 2014)
Larry Ball (Honeywell, USA), Jun. 15, 2014 (Japanese translation: Toru Nakagawa (OGU)), Preface for the Japanese Edition of Larry Ball's "Hierarchical TRIZ Algorithms" (Translated by Toshio Takahara and Toru Nakagawa, Published by the CrePS Institute, Jun. 30, 2014)
A 7-page Preface newly written down by the author for the Japanese Edition. "Hierarchical TRIZ Algorithms" was originally posted in the TRIZ Journal in 2005-2006 and was presented in his Keynote Lecture at Japan TRIZ Symposium 2007. The present article describes its essence reflecting his further development. He has decomposed all the TRIZ tools together with various other methods related to product development and market development, and has reorganized them into an integrated process. The guideline for the reconstruction is to clarify the input/output information of processes and to follow the logical pre/post relationships among the processes; he calls it a hierarchy of decision and finds a hierarchical algorithms for product development. There are cases when an engineer comes up with an idea of a product, draws a prototype design, and requests for the funding. Such cases fail very often, as statistics show, because he has started the project at a down stream after arbitrarily assuming the information to be decided at upper streams, the author says. The Hierarchical TRIZ Algorithms advises the transfer from 'selling what we can make' to 'making what we can sell'.

TRIZ Paper: Lean-TRIZ instead of TRIZ-Lean (May 31, 2014)
Christian M. Thurnes (Univ. of Applied Sciences Kaiserslautern, Germany) and Frank Zeihsel (Synnovating GmbH, Germany), 13th ETRIA TRIZ Future Conference (TFC2013), pp.789-795, Oct. 29-31, 2013, Ecole Nationale d'Arts et Metiers of Paris, France; Introduction in English: Toru Nakagawa (OGU); Japanese translation: Toru Nakagawa (OGU), May 22, 2014
The authors have clear motivation in the present work: Recently in many companies in Germany (and in Japan and all over the world) the "Lean" (or Lean engineering/management, i.e. Toyota's production/development system) has been introduced actively. Lean and TRIZ are the methodologies having the targets in common to improve and solve problems in the systems of product development and production processes, etc. In fact, however, Lean practitioners rarely use TRIZ even though they are aware of it. Is there any way to integrate/cooperate the two methodologies, or for TRIZ to play a significant role in the Lean situations? The authors presented their thoughts in the conferences and groups having both TRIZ and Lean members, and through discussions and experiments they have found a new different approach.
Initially the authors proposed and tested the "TRIZ-Lean" approach where the TRIZ principles (e.g., Inventive principles and ideality) are explained or concretized with the ideas and examples in Lean. TRIZ practitioners accepted the approach, but Lean practitioners rarely found its significance, saying "Lean is good enough without TRIZ".
Then they found a new approach, "Lean-TRIZ", where the two methodologies are kept as they are and in the Lean prevailing situations TRIZ should be used at the Lean's blind/weak points for supporting Lean. More concretely, the problems which are recognized as 'necessary wastes (NVA)' in Lean are defined as contradictions in TRIZ and are solved with ordinary TRIZ tools. In the Lean product development process, several TRIZ tools are used. On the occasions of 'events' in Lean, TRIZ sessions or TRIZ workshops fit well to work for these purposes. The Lean-TRIZ approach has been tested and has obtained positive evaluations by Lean practitioners. In practice, the authors advise to respect the Lean philosophies such as 'Test to design' and 'Set-based concurrent development' and to perform TRIZ in relatively short subsessions. -- This paper reflects the discussions and practices in the methodological as well as practical aspects. This work shows us insightful directions for promoting TRIZ in the real world.

TRIZ Paper: Freeform Innovation and Ideative Energy (May 14, 2014)
S. Saleem Arshad (Applied Innovations, Australia), Apr. 23, 2014
'Freeform Innovation' proposed here by the author is a simple and powerful process for generating creative ideas, as is explained and demonstrated with a simple example. In this concise paper of 10 pages we can understand the basic approach of FI, which has just a two-step structure, i.e., 'Active Observation' and 'Active Thinking'. The process is driven intuitively and effectively with the emphasis of improving/adding functionality. In combining and then uniting the ideas/functions of A and B, the author uses the notations like A+B and then (AB). The present paper contains some more new terms and new concepts, e.g., Ideative energy (on the user side and on the product side), Flow of ideative energy, etc. They must have a wealth of potential for further investigation and discussion.
TRIZ Paper: Understanding Secrets of Sustainability through TRIZ Philosophy (May 14, 2014)
Umakant Mishra (India), Apr. 9, 2014
This is a clearly written overview paper discussing on the 'Sustainability' in a general and conceptual level, to understand its secrets. The philosophy (not individual tools) in TRIZ has guided the understanding. Such TRIZ concepts are: Cause-effect relationships; Super-, Sub-, and Co-Systems; Resources; Contradictions; Ideality; etc. The paper is written in an abstract and conceptual level and yet very clearly to discuss the real problems to solve and goals to achieve the Sustainability. How to achieve the Sustainability still need to be investigated; I wish to read the author's forthcoming paper.
Mishra's book "TRIZ Principles for Information Technology" is going to be published soon by CrePS Institute in the Japanese Edition as Vol. 4 of "TRIZ Practices and Benefits" Series

TRIZ Paper: Methodology: From Altshuller’s 76 Standard Solutions to a new Set of 111 Standards (Apr. 30, 2014)
Davide Russo and Stefano Duci (University of Bergamo, Italy), 13th ETRIA TRIZ Future Conference (TFC2013), pp.305 - 315, Oct. 29-31, 2013, Ecole Nationale d'Arts et Metiers of Paris, France; Introduction in English: Toru Nakagawa (OGU); Japanese translation: Toshio Takahara ( ) and Toru Nakagawa (Osaka Gakuin Univ.), Apr. 28, 2014
This paper deals with the Su-Field Modeling and the Inventive Standards originally developed by G. Altshuller. His methods intend to focus down the problem situation into a minimal system model of two substances and the interaction between them, and to recommend some suitable solution strategies according to the type of the problem patterns. However, for ordinary TRIZ users, his Triad representation of the Su-Field Model looks particular and the system of 76 Standards seems difficult to parse; and hence these two methods have not been used so widely. The present authors have reorganized these two methods by following Altshuller's original aims:
First, the authors adopted the commonly used concepts of functional analysis for modeling the minimal system with the two substances (Tool and Object) and the interaction (action or function) between them. Then the problem situations are classified into the cases of 'Harmful/Excessive action' and 'Insufficient/Missing action' (besides the cases of 'Measurement/Detection' and 'Incomplete minimal system'). Solution strategies for the 'Harmful/Excessive action' are expressed with 6 different verbs: 'Deflect', 'Block', 'Make unable', 'Make insensitive', 'Combine (the system)', and 'Reduce' the harmful action. Similarly for 'Insufficient/Missing action' the strategies are expressed with different 6 verbs. Such strategies are called 'Actions'. The Actions can be applied onto the elements of the minimal system in only 4 ways; they are 'Add a substance', 'Modify a substance', 'Add a Field', and 'Modify a Field'. These 4 ways are named 'Suggestions', and are described in more detail by using the information contained in the original 76 Standards. In this manner, the present authors have proposed a new, reorganized system of Standards, composed by 25 'Action-Suggestion' pairs of solution strategies.
*** The new system has a simple overall structure and easy-to-understand description of individual Standards. The present paper is excellent in reorganizing (or modernizing) the Su-Field Model and the Standards, following Altshuller's original intention. I wish that the world TRIZ community accept this new system for wider penetration.

Announcement: Publication Announcement of the Japanese Edition: Darrell Mann's "Matrix 2010: Re-updating the TRIZ Contradiction Matrix" (Apr. 17, 2014)
Toru Nakagawa (OGU and CrePS Institute), Apr. 17, 2014.
As the second volume of "TRIZ Practices and Benefits" series
'Contradiction Matrix' is known as a typical method in TRIZ, but in fact it had a peculiar history of development and evaluation. The Contradiction Matrix published today in most (i.e., except Mann's) TRIZ textbooks is the one of size 39×39. It was originally developed by G. Altshuller with tremendous paper-and-pencil efforts by the beginning of 1970s. Engineers at that time, and nowadays as well, were much attracted to it with the great vision and results. However, Altshuller himself evaluated its usefulness below his expectation, and hence he omitted this method from ARIZ (i.e., the standard process of TRIZ) in mid 70s and did not recommend it any longer to his students. When TRIZ was introduced to the Western world in 90s, basic and earlier knowledge of TRIZ was mostly brought in, and Contradiction Matrix became popular. It has been used in the old form, because updating it would need a huge work.
Darrell Mann et al started the big project of updating Contradiction Matrix in 2000; they analyzed all the US patents granted since 1985 to establish an updated Matrix with full usage of modern IT tools. Their Matrix 2003 is of size 48×48, while Matrix 2010 size 50×50. Categorization into parameters and the suggestions of applicable Principles have become easier to understand and apply. As the progress in science and technology, the contents of the Contradiction Matrix should also evolve, Mann says. I believe that we should use the updated Matrix instead of the original but old one, for appreciating and furthering the vision and philosophy of our TRIZ Father.

TRIZ Paper: TRIZ Propagation: Effective strategy to introduce and propagate TRIZ into companies based on the bad and good experiences in Korea (Apr. 2; Apr. 9, 2014)
Kyeongwon Lee (Korea Polytechnic University (Korea) & INSA Strasbourg (France)), 13th ETRIA TRIZ Future Conference (TFC2013), pp.641-648, Oct. 29-31, 2013, Ecole Nationale d'Arts et Metiers of Paris, France; Bibliography and Japanese translation: Toru Nakagawa (Osaka Gakuin Univ.), Mar. 29, 2014
Korea is the country most successful in introducing, propagating and applying TRIZ in industries, among the countries in the world. In the initial stage of introducing TRIZ in Korea (ca. 1996 - 2005), TRIZ was not accepted widely because of various barriers and bad experiences, the Author says. The situation was changed by the success of practical industrial examples developed in Samsung by Russian TRIZ experts employed at TRIZ promotion department. Executives of Samsung recognized the success, and promoted to develop education and training programs and expand the application of TRIZ to real projects. Such TRIZ activities were expanded to other big industries in Korea, and were carried out with much enthusiasm as a big movement in Korean industries, he says. On the basis of 'bad' and 'good' experiences the author suggests 'Effective strategies' for introducing and propagating TRIZ in industries. PDF files of the paper
I collected the papers concerning to TRIZ activities in Korea as a bibliography
TRIZ Forum: Southbeach Forum: Brief Guide of How To Use the Southbeach Modeller (in the Editor Mode) (Apr. 2, 2014)
Toru Nakagawa (Osaka Gakuin Univ.), (Jun. 9, 2013 in Japanese
The Southbeach Modeller is a very sophisticated and excellently designed software tool. It has so many functions, features, and options, and yet is shown on the window in a very compact way. It has a rich library of white papers, specifications, demo videos, sample outputs, and examples made by developers and users. The usage of the software is mostly intuitive. However, its users meet some difficulty for starting up. A lack of Users Manuals may be the weak point. I think NOT a Reference Manual but a brief & easy Guide is needed for the beginners of the Southbeach Modeller. Thus I wrote this Guide a year ago, for assisting the beginners to get started in using the Southbeach Modeller in the Editor Mode (i.e., for building the models). And today I am posting it in English translation.
TRIZ Education Case study: 12 Years of Lecture and Seminar Classes on 'Methods of Creative Problem Solving' (Mar. 16, 2014)
Toru Nakagawa (Osaka Gakuin Univ., Professor Emeritus), Poster presentation at the 2nd Conference of Innovation Education Society, held on Mar. 10-11, 2014 at Keio University, Hiyoshi Campus, Yokohama.
'Innovation Education Society' of Japan was established last year. Its core groups were formed by 3 prestageous universities, i.e., 'i.school' of the University of Tokyo, SDM (System Design Management Course) of Keio University Graduate School, and QREC (Robert T. Huang Entrepreneurship Center) of Kyushu University. The society is going to develop and promote the methods and systems for educating the motivation, mindsets, skills and techniques, leadership etc. necessary for achieving innovation, towards undergraduate and graduate students (and young engineers and business people). The conference this year obtained over 200 participants from universities and industries, and over 40 case studies presentated with posters in parallel. Most people are interested in how to motivate and acquire skills in social and business oriented areas. I presented my 12 years of experiences of education at OGU in the field of (technical) creative problem solving, which forms the basis of 'Innovation' in most cases, I believe. 8 slides in Japanese.

Editorial: Message: Start of CrePS Institute and publication of "TRIZ Practices and Benefits" book series (Editor: Toru Nakagawa (Osaka Gakuin University and CrePS Institute)) (Feb. 16, 2014)
For starting the publication of TRIZ book series, it has become necessary for me to take the official business responsibility as a publisher. So I have just started 'CrePS Institute', a sole proprietorship, and have become its Director. Its activites are to be: Research, education, and proliferation activities of creative problem solving methods (e.g., TRIZ, USIT, CrePS, etc.).
TRIZ Paper: Innovation: Thinking Differently to Create Value (Jan. 26, 2014)
S. Saleem Arshad (Applied Innovations, Australia), Jan. 25, 2014
I received this paper from Dr. Arshad as his final version after several turns of communications since last autumn. He has raised a question about the real contents of the fashionable keyword "Innovation". Behind the current global trend of pursuing "Innovation", something different and more fundamental has been lost, he discusses. He shows a two-dimensional space for categorizing various studies and methods of how to achieve "Innovation" (including improvement and problem solving, etc.), where one axis is along the outcome-based vs. process-based approaches and the other axis along the conceptual knowledge vs. practical knowledge. He argues the needs of works with more process-based approaches and of more practical knowledge. -- In recent years the global TRIZ community have made various activities and progresses in TRIZ, and yet I feel we are losing the ground of TRIZ in some aspects. We need to reconsider our standing points and our directions to go. I wish you to contribute your thoughts to open discussions in the present Web site and elsewhere. PDF.
TRIZ Paper: Case study: In-house Promotion of TRIZ Use through Practice (Jan. 26, 2014)
Shigeru Hisanaga, Hiroshi Takenaka (DENSO Corporation) (English translation by the Japan TRIZ Society), Presented at 9th TRIZ Symposium in Japan, Held on Sept. 5-6, 2013 at Institute of Mathematical Statistics, Tachikawa, Tokyo
This paper was presented last September at the Japan TRIZ Symposium 2013 and received the 'Award of Best Presentation for You' according to the participants voting. DENSO Corporation, as you may know, is a big company in the TOYOTA group taking charge of the electronic equipment and interiors. This paper reports that DENSO has introduced and applied TRIZ for these 10 years to about 250 projects. They suggested in conclusion: "There can be different ways for promoting TRIZ in an industry. Promotion through 'Real practices' is one of them, i.e., To apply TRIZ anyway to real job tasks, to have many experiences of small successes and failures, and through such lessons, to find new approaches and tools suitable and useful for ourselves."

TRIZ Paper: Case study: 7 Solutions to extend the application of TRIZ - Including the prevention of design risk - (Jan. 26, 2014)
Takashi Ogata, Kazuhiro Fujikawa (OLYMPUS Corporation), Presented at 9th TRIZ Symposium in Japan, Held on Sept. 5-6, 2013 at Institute of Mathematical Statistics, Tachikawa, Tokyo
This paper was presented last September at the Japan TRIZ Symposium 2013 and received the 'Award of Best Presentation for You' according to the participants voting. Mr. Ogata has won the Awards 3 times running since 2011!! In Olympus Corp., the authors have introduced the scientific methods like QFD, TRIZ, and Taguchi Method since 2009. From the start they tried to introduce the methods on the standpoints of engineers, so as to be quick and effective in their busy schedule, and to select and apply suitable tools depending on their purposes. At the presentation this year, they have shown 7 sequences of applying selected tools (elements in QFD, TRIZ, and TM) for different purposes. They call them '7 Solutions'. (-- In Japanese IT jargon, 'Solution' means a software system or method /process to be applied to some big user's jobs.) They describe the processes and methods in each 'Solution' and explain the basic concepts underpinning the seven Solutions. I evaluate this paper unique and valuable from the international viewpoints and hope it useful and stimulative for many readers in Japan and in the world. PDF
Editorial: Message for the New Year 2014 (Editor: Toru Nakagawa (Osaka Gakuin University)) (Jan. 26, 2014) (Jan. 11, 2014)
Greetings from Japan! I posted this New Year message in Japanese on Jan. 11, but in English only now, near the end of January. You see my New Year card (in Japanese) and three enlarged photoes: aurora in Finland and opera at the Arena of Verona, Italy. The society in Japan (as well as in the world) is facing with many complex and serious problems. (Unfortunately, the current Japanese government intends to go in a wrong direction.) For addressing to such complex problems, we need to build effective methodologies of problem solving and apply them to the real practices in various places. The demands in society are so huge but our power for building tools is so limited. I would like to make our best efforts step by step in cooperation with you.

(English translation of slides by the Japan TRIZ Society) , Presented at 9th TRIZ Symposium in Japan, Held on Sept. 5-6, 2013 at Institute of Mathematical Statistics, Tachikawa, Tokyo
This is an excellent report of the work conducted by a study group of JTS for these 4 years. In the field of business and management application of TRIZ, the authors have chosen the success of Yamato Transport Co.'s "TA-Q-BIN" (Door to Door parcel Delivery Service) business as the model of their case study. The authors studied to identify contradictions in the historical situations around the business; they also evaluated the present stage of evolution in several aspects of the business and estimated the next future stage of evolution. This is a valuable case study of applying TRIZ to business problems; the case is of special interest as a unique service business developed for these 40 years in Japan.

TRIZ presentation: Universal Trends of Evolution in form of USE and USESoft (Dec. 9, 2013)
Alex Zakharov (USA), September 12, 2013
I received this presentation from Alex Zakharov attached on his communication regarding my CrePS proposal. He has shown the scheme of trends of evolution of (technical) systems in a diagram named 'Universal Trends of Evolution (USE)'. He proposes to collect various information concerning to the target system and to map them in this diagram. Using intelligent internet search, artificial intelligence software of the USE diagram, and 'scientist-robots' together, a 'Discovery machine' can be built in future, he says. The USE diagram apparently well represents the hierarchical nature of system evolution, I feel. Slides in PDF

Among the communications I have received recently, I am going to post here some of those suitable for open discussions.
Darrell Mann gave a comment saying: "Difficulties in the innovation are to identify a 'right' problem and to execute the ideas generated. Problem solving itself is rather easy." I responded, from my viewpoint of the Six-box Scheme of CrePS, saying: "The two difficulties raised by Darrell need to be considered in the 'Real World'. Whereas the main part of problem solving should be carried out in the 'Thinking World'. The methodologies of problem solving, including TRIZ, have not found a good framework (i.e., scheme or paradigm) and hence have been confusing. Introducing the framework of the Six-box Scheme and establishing CrePS, the problem solving methodology in the 'Thinking World' will become clear and systematic. It will certainly give the basis for innovations and contribute to much wider areas of application." There are 2 other communications related to the Southbeach Modelling software.

TRIZ Forum: Conference Report (29) : Personal Report of The 13th ETRIA World TRIZ Future Conference (TFC 2013) (Nov. 17, 2013) (Dec. 9, 2013)
Professor Manabu Sawaguchi and his 3 graduate students participated in and presented at the ETRIA TFC 2013, held at ENSAM-Paris on Oct. 29-31, 2013. Mr. Izumi reports his impression: "The ETRIA TFC is a conference on TRIZ held every year in Europe, with the attendance from not only Europe but also USA, Asia, and Mid East, etc. The conference is participated by people both from academia and from industries; it has 41 presentations in the Scientific session and 35 in the Practitioner session. It was impressive that 20 among 140 participants are from Korea, where TRIZ is accepted and used actively. I briefly introduce 4 presentations of my interest."
The 3 days conference had 8 invited talks and 72 presentations, with about 150 participants form about 30 different countries. I attended and presented a paper at the conference. The official Web site of the conference is:In my Personal Report (of 5 pages in Japanese), I have listed up 37 presentations of interest with brief introduction and categorized them according to their topics. I wish to post several selected papers in English and in Japanese translation here in near future. ==> Personal Report is posted in English (Dec. 9, 2013).

Creativity lecture: Creative Company and Methods (Nov. 17; Nov. 18, 2013)
Makoto Takahashi (SOKEN Research Institute, Japan), Special Invited Talk presented at 4th Global TRIZ Conference in Korea (GTC2013), Held on July 9-10, 2013 at Seoul Trade Exhibition& Convention, Seoul, Korea
Dr. Makoto Takahashi has been one of the top leaders of the creativity movements in Japan since 1960s. In 1974 he started a creativity consulting firm 'SOKEN Research Institute' and is its Chairman; he has been guiding a large number of companies and municipal offices, etc. He is ex-President and ex-Chairman of the Japan Creativity Society (JCS), and is also Special-appointment Professor of Japan Graduate School of Professional Education. He has authored or edited about 70 books, including "The Bible of Creativity" (in Japanese) published in 2002.
In the present lecture he talks about the history and thoughts of his and Japanese creativity movements by using a variety of real cases. For instance, in the case of the reforming of Asahiyama Zoo in Asahikawa city, Hokkaido, a big success was achieved by constructing a concept of 'Making it possible to see the characteristic natural behaviors of (rather familiar) wild animals closely and naturally'. He talks about how the creative company should be managed and also suggests that various creativity methods should be used more effectively in TRIZ. -- In the Editor's Note at the end of this page, I am discussing on the overview of creativity methods, in response to Dr. Takahashi's overview.
On the 15th Anniversary of "TRIZ Home Page in Japan": Toru Nakagawa (Nov. 17, 2013)
This Web site "TRIZ Home Page in Japan" celebrates its 15th Anniversary on Nov. 1 together with readers in Japan and over the world. This site is to promote the understanding and real usage of TRIZ by openly publishing information and communications related to TRIZ on a not-for-profit basis. Though I have been operating this site as a volunteer, this site is not a personal site but a public forum to be composed of the contributions by readers, as you see already. Most pages are published in Japanese and in English in parallel for the purpose of mutual understanding and collaboration between Japanese and overseas TRIZ learners/practitioners. I envisage that Pubic Web Sites built in different TRIZ Communities will form A Global TRIZ Community with much reduced language barriers

For the purpose of encouraging the trial use and evaluation of the Southbeach Modelling, I started the "CrePS-SB Project" in Japan in June 2013 and it is now open to the users outside of Japan. For reducing the cost barrier for the trial of making models with the software tool, I have arranged, under the permission of the Southbeach Solution Co., to offer free '3-month Editor mode license' to any voluntary users who are willing to share their experiences. A brief note by a month and a report useful for other people will be requested to the members. The procedure is shown in this page.
TRIZ/USIT/CrePS Paper: General methodology for creative problem solving and task achieving (CrePS): Its vision (Oct. 3; Oct. 25, 2013)
Toru Nakagawa (Osaka Gakuin University), the 35th Conference of Japan Creativity Society, to be held on Oct. 26-27, 2013 at Nihon Institute of Medical Science, Moroyama-machi, Saitama (in Japanese);
Toru Nakagawa (Osaka Gakuin University),13th ETRIA TRIZ Future Conference (TFC2013), to be held on Oct. 29-31, 2013, Ecole Nationale d'Arts et Metiers of Paris, Paris, France (in English);
This page posts a full paper on the 'General methodology of Creative Problem Solving and Task Achieving (CrePS)', which I have been advocating these days, with the focus on its vision. The Japanese paper for JCS Conference is addressed to the audience who are working for creativity education, practical applications of problem solving techniques, etc. (with few people familiar with TRIZ), and hence it emphasizes on the needs of unifying various creative problem solving methods into a general methodology. On the other hand, the English paper for ETRIA TFC is addressed to TRIZ specialists/practitioners and thus it is introduced by emphasizing the significance of establishing a general methodology of creative problem solving across the border of TRIZ.
The bodies of the two papers are essentially the same. They assert that by introducing the 'Six-Box Scheme' as a new paradigm, various approaches of creative problem solving, including TRIZ, can be integrated smoothly into a unified system, i.e., a general methodology, of rich techniques of creative problem solving. The methodology consists of three major parts: (a) Initial part (from Box-1 to Box-2): in the 'Real World' we should grasp a problem and make a clear focus on it. (b) Main part (from Box-2 through Box-5): in the 'Thinking World' we should analyze the problem, understand the present system, make images of ideal systems, generate ideas for new systems, and then build them up into conceptual solutions. (c) Succeeding part (from Box-5 to Box-6): in the 'Real World', we should implement the conceptual solutions into specific real solutions in our new products/services. The papers describe the contents of them in tables.
We, together with you, can establish such a general methodology, and by handing it out to many different people in the country and in the world, it can be applied to various problems in different fields in the whole country and in the whole world to obtain creative and peaceful solutions. -- This is the vision and message of these papers.

Introductory Video on TRIZ/USIT/CrePS: Let's Master How to Think for Creative Problem Solving (Oct. 3, 2013)
Internet casting on USTREAM, "Inventor Nagaya's Talk Show on Innovation of Education", Guest: Toru Nakagawa (OGU), Sept. 27, 2013, 19:15- JST. Video Archives: USTREAM http://www.ustream.tv/recorded/39283391 ; YouTube: http://www.youtube.com/watch?v=cxpQNTiRzBQ
Mr. Kenichi Nagaya is an inventor and entrepreneur at his emerging company Netman, which is working for the innovation of education with the emphasis of IT and communications. Nakagawa was invited as a guest of his Talk Show on USTREAM internet casting. It was a live show for 30 minutes on evening Sept. 27, and is archived in both USTREAM and YouTube. I am trying to introduce how to think creatively in problem solving towards common people. I talked on the conventional approaches, TRIZ contribution, a simple example of using USIT, and the general method in the Six-Box Scheme. The 15 slides I used
Forum: Southbeach Forum: Trial Use Report (1): Report of 3-month trial use of Southbeach Modeller (Oct. 3, 2013)
Morimasa Okada （YorkMart Co.）, Sept. 18, 2013.
This is the first report of 3-month free trial use of the Southbeach Modeller in the CrePS-SB Project. He reports:
"Purpose: To make models of the functions of a supermarket for the purpose of visualizing how to reform the conceptual design of deploying supermarkets and how to develop new business models. Impressions: Even though the problem situations are vague and complex, the software tool supports us to build the model of our vision intuitively and smoothly. Thus it is pretty useful for constructing new functionality of the stores and business. ... Examples: Three of the models I made are disclosed here. (1) Conceptual design of a smaller-scale supermarket to be deployed in downtowns and residence areas. (2) Model of retail functional units, (3) Model of roles of Visionary, Knowledgeable, and Implementing persons in the case of problem solving in retail functions. ... I wish to accelerate the evolution of supermarkets by using this Southbeach Modeller. With a Japanese edition of the software tool, it would be much easier to use."

Forum: Fukushima nuclear accident: FUKUSHIMA Report (1): Criminal error in TEPCO management of technology and damages given to "Brand Japan" (Sept. 20, 2013)
Eiichi Yamaguchi (Doshisha Univ.) and Morinosuke Kawaguchi (Arthur D. Little (Japan), Inc.) (Fukushima Project Committee), News Release, Nov. 2011
In the Japanese page: 'Core problem in the TEPCO nuclear plant accident -- Similarity with the JR West train accident at Amagasaki', by Eiichi Yamaguchi (Doshisha Univ.), Talk on Feb. 26, 2013; published in "Bulletin of YMCA, The University of Tokyo", Aug. 6, 2013.
On the Fukushima nuclear plant disaster in March 2011, reports were published by four major mutually-independent investigation committees ('Jikocho'); they were 'Minkan (i.e., voluntary)', 'TEPCO', 'Diet organized', and 'Government'. Since there are so many different aspects to discuss and various facts are not disclosed well yet, the four major Jikochos have different views of the problem. The 'FUKUSHIMA Project' is the fifth, so-to-speak 'Grass-root' Jikocho and published their report in January 2012. It says: "The final cooling system, RCIC and HPCI of No.3 and RCIC of No.2 Nuclear Reactor were correctly operated (for 35 hours for No.3, and for 70 hours for No.2) even without AC power even though Tsunami had destroyed the emergency power system. Therefore, if TEPCO opened the vent and injected the sea water during the controllable dimension, the reactors would never be out of control. However, in reality, the management of TEPCO kept refusing the sea water injection. Thus, the root cause of this accident is NOT the technology BUT the technology management of the TEPCO management." In the Japanese page, I am posting the 10-page article

TRIZ (Business) Paper: Strategies for Small Businesses: "The Mind of the OutCompete Strategist: Dozen Business Strategies to Win Against All Odds" (Sept. 20, 2013)
Len Kaplan (in South Korea), July 13, 2013.
The author was working as a TRIZ specialist for a TRIZ vendor in US for many years and then moved to South Korea about 4 years ago. He wrote down this article newly for this Web site as a summary of his book published in 2009. He discusses on possible strategies for an emerging small business which is going to get serious attack from business giants just after the first 'success' of the small business. The author advises for small businesses to make well prepared beforehand and escape from such an attack by going away with different products or to different markets. The strategies, as the author emphasizes, are counter-intuitive and look very difficult to perform. But, for that same reason, they are the only ways for small businesses to survive and grow in the competing business situations. Each chapter of the book discusses the 12 strategies one by one, with the descriptions of executive summary, business dilemma, sketch of strategy, (one or two) black case studies, and (one or two) white case studies. The article is shown in HTML and in PDF
TRIZ/USIT/CrePS Paper: For Establishing A General Methodology of Creative Problem-Solving / Task-Achieving (Aug. 22, 2013)
Toru Nakagawa (Osaka Gakuin University), Presented at 4th Global TRIZ Conference in Korea, Special Invited Talk, Held on July 9-10, 2013 at Seoul Trade Exhibition& Convention, Seoul, Korea
This page posts the presentation slides of my Special Invited Talk presented last July at Global TRIZ Conference 2013 in Korea. (Participation report of GTC2013 in Japanese
TRIZ Forum: TRIZ Conference Report (27): Participation Report of 4th Global TRIZ Conference (GTC2013) in Korea (Jul. 9-10, 2013, Seoul) (Aug. 4, 2013)
Toru Nakagawa (Osaka Gakuin University), Aug. 1, 2013. [In Japanese only.]
Being invited for a Special Invited Talk at GTC2013, I visited Korea for the first time. Keynote Lectures were given by Dr. Simon Litvin (USA) and Ms. Karen Gadd (UK), and Special Invited talks were given by Dr. Makoto Takahashi (Japan, former President of Japan Creativity Society) and me. About 230 participants from 9 countries other than Korea; 39 contributed papers were presented. It is remarkable that nearly 10 Russian TRIZ experts working (or used to work) for Korean industries attended at the Conference. This year, in response to the organizers' encouragement, many presentations on real TRIZ applications were given by industries including Samsung and POSCO. Presentations were also given on improvement and further development of the TRIZ methodology and on TRIZ education and TRIZ-based education. The Conference was active and well organized with much fruits.
I realized that Korea has already passed the early stage where Russian TRIZ experts who are employed in Korean big industries had much influences, and now has a large number of Korean TRIZ leaders and practitioners, who are actively working in industries, in academia, and in consulting firms.
TRIZ Forum: Paper: A Review of Japanese References on Scientists’ Responsibility (Aug. 4, 2013)
Kana Okawa (Japan Advanced Institute of Science and Technology (JAIST), PhD Student), Presented at 3rd Forum on Knowledge Co-Creation, Held on March 2-3, 2013 at JAIST Tokyo Office, Tokyo; Published in "Forum on Knowledge Co-Creation" on Jul. 26, 2013, URL: http://www.jaist.ac.jp/fokcs/papers/S_paper_Okawa.pdf
After the March 11 Disaster in Japan due to the M9.0 earthquake, tsunami, and the nuclear power plant accident in 2011, Ms. Kana Okawa started this study. She wanted to reconsider "What scientists, and myself, should do?". She collected books and papers (written in Japanese) which contain the keywords such as 'scientists', 'responsibility', 'ethics', etc. in their titles or abstracts. Reading over 140 such references she wrote this review paper.
Attending at her presentation I was much impressed with her intensive work and her serious attitude. I wish the "TRIZ Home Page in Japan" may be of some help for her work to be known to wider audience in Japan (and possibly in the world in future). In Japanese: Paper in HTML
TRIZ Paper: A Note on Movement and Contradiction in Technology and Institution (Aug. 4, 2013)
Toshio TAKAHARA ( ); Paper originally published in "TRIZ Home Page in Japan", August 4, 2013; Received on Nov. 22, 2012
Toshio Takahara's latest paper in 20 pages in Japanese and in 14 pages in English. His works for these 10 years on the "Theory of Resolving Differences" (i.e., theory of problem solving and task achieving) are documented in two collections ( in 2008
'Technology' means an assemblage of technical means, which intermediate human interactions towards the nature, and the processes of generating, utilizing and operating it. And 'Institution' means an assemblage of common ideas, which intermediate human interactions towards the community, and the processes of generating,utilizing, and operating it. For the purpose of understanding these consistently, the author considers about everything perceivable (i.e. 'Objects', including things and ideas and interactions) and their relations and changes (i.e., 'Movement', in Takahara's terminology). In the present paper he especially discusses and extends the concepts of 'contradictions' and 'dialectic'. Paper in Japanese
TRIZ/USIT Paper: For Establishing General Methodology of Creative Problem Solving & Task Achieving (Jun. 22, 2013)
Toru Nakagawa (Osaka Gakuin University), Presented at 3rd Forum on Knowledge Co-Creation (FoKCs), Held on March 2-3, 2013 at JAIST Tokyo Office, Tokyo
On the topic related to the present paper, I already gave several talks/papers among the TRIZ communities, e.g. at Japan TRIZ Symposium 2012
'A general methodology' of creative problem solving is not established yet. Even though there are a large range of individual techniques and approaches, we need a good framework to integrate them. Such a general methodology should be a super system holding various individual methods (techniques, tools, approaches, etc.) and integrating them in a systematic manner with some framework. For such a framework, I propose to overcome the conventional 'Four-Box Abstraction Scheme' (which is used not only in TRIZ but also very widely in science and technology) and to introduce the 'Six-Box Scheme' which was found in USIT. Using the Six-Box Scheme as the basic framework, we will be able to build a general methodology for creative problem solving.

Editorial: Southbeach Forum on Southbeach Notation and Modelling: A Forum for Introduction, Communication, and Evaluation (Jun. 9; Aug. 4; Oct. 3, 2013)
Toru Nakagawa (Osaka Gakuin University), Jun. 9, 2013.
This page intends to be a discussion forum on Southbeach Modelling, including its visual languageStarting to post the messages from the users who are trying to use the software: The first message is from Mr. Morimasa Okada, who wants to visualize the situations of his supermarket for the purpose of developing the stores. (Aug. 4, 2013)
Morihisa Okada has contributed his report of 3-month trial use; it contains 3 models made with SB Modeller.
Toru Nakagawa (Osaka Gakuin University), Jun. 9, 2013.
For the purpose of encouraging the trial use and evaluation of the Southbeach Modelling, I started the "CrePS-SB Project" in Japan. Especially for reducing the cost barrier for the trial of making models with the software tool, I have arranged to offer free '3-month Editor mode license' to a group of volunteers. A brief note by a month and a report useful for other people will be requested to the members. The procedure is shown in this page.
==> CrePS-SB Project is now open to voluntary people outside of Japan
Toru Nakagawa (Osaka Gakuin University), Jun. 9, 2013.
This page intends to accumulate notes on how to use Southbeach Modeller.
When I translated Howard Smith's White paper into Japanese, I myself drew the 27 diagrams in Japanese with the use of Modeller while looking at the printed English versionｓ. The drawing work was done in less than a day. I was much impressed with the software tool in its easiness to learn and convenience to use. I have posted a note on how to use the Modeller for beginners.
TRIZ Paper: Red, Green, and Blue - Situational Improvement Using Southbeach (Jun. 9, 2013)
Howard Smith (CSC European Group, UK), BPTrends (Business Process Trends), Jan. 4, 2011; White Paper, Southbeach Solutions Ltd., UK; Introduction and Japanese translation: Toru Nakagawa (OGU), Jun. 6, 2013
The present paper describes the basic language implemented in the Southbeach Modeller
I was most impressed with the present paper in the point that the modelling method allows to represent different and conflicting views and opinions with the diagrams and to guide the group of different people toward alignment for improving the situation. The author explains such a process convincingly (or 'logically') by using a number of examples. He talks about contradictions and problem solving in common cases in the business field instead of technological field. I feel his explanations fresh and insightful, and are easy and convincing for people in non-technological fields. The present modelling method/tool can be used universally with a large range of methods and techniques for problem solving and group decision making.

TRIZ Software Tool: Overview of Southbeach Modeller 3.0 : A General Purpose Software for Building Thinking Models (May 29, 2013)
Southbeach Solutions Ltd., White Paper (2013), http://www.southbeachinc.com/papers/Southbeach Overview.pdf; Introduction and Japanese translation: Toru Nakagawa (OGU), May 27, 2013
Here is a software tool developed recently in UK, under the influence of TRIZ tool for Cause-Effect diagrams and being extended much further for building various types of thinking models in an easy and generalized manner. The developers had the motive of improving the ways of business process innovation by introducing modern TRIZ. They made a basic plan around 2006, established their model description language 'Southbeach Notation' in 2008, and have been implementing it into a software tool. In 2011, Howard Smith published a paper describing the possibilities of how such an easy modelling tool can support idea generation and communication in human and technology problems. They have just released the Modeller 3.0 and published its Overview. Their Web site discloses a rich library of documents including many application examples. I suppose that the present tool is rich in descriptive power, general purpose usage, functionality, and also handy and inexpensive. I am impressed with their idea of "Just like Spread Sheets for numbers, Modelling Sheets for ideas". Under the permission by SB, I have translated their Overview slides into Japanese and am posting them in HTML.
Promotion Case Study: Establishing TRIZ in a global company (May 29; Aug. 4, 2013)
Pauline Marsh (BAE Systems, UK), Karen Gadd (Oxford Creativity, UK),ETRIA TRIZ Future 2012 Conference, Held on Oct. 24-26, 2012, at Lisbon, Portugal; Proceedings, pp. 553-566; Japanese translation: Toru Nakagawa (OGU), May 22, 2013
This is the first and detailed report of the 14 year experiences of establishing TRIZ in a global company, BAE Systems, in UK. TRIZ has been introduced and promoted steadily since 1998 and are used company-widely. Selecting proper methods (including TRIZ) and proper instructors, incorporating the courses in the already established HR programs, promoters within BAE made TRIZ available to any individuals and teams as they needed. The BAE promoters initially organized and participated the TRIZ workshops for themselves, and at some important occasions they checked the real outcomes of the method and of the trainings. The consultants at Oxford Creativity operated workshops for practical problem solving; they are regular 5-day courses designed to be taken as five 1-day courses as well. In the workshops, they first gather initial ideas from everybody by a brainstorming, openly discuss good and bad points of the ideas, and set them all aside with the labeling of 'BAD solutions' for the purpose of exploring for BEST solutions with TRIZ. Their workshops are always fun and enthusiastic, they say. The authors repeatedly write that 'Individual TRIZ tools are simple and straightforward, and they stimulate your thinking'. They strove to persuade engineering managers for making TRIZ available to the whole engineers in the divisions; they have found that challenging real difficult problems to solve with TRIZ is most effective for convincing the managers. The present paper is full of lessons based on their experiences. English paper in PDF

TS Yeoh (MyTRIZ President; Intel Malaysia), Keynote Speech presented at Malaysia TRIZ Conference 2012 on November 7, 2012, at Penang, Malaysia; Annotation and Japanese translation by Toru Nakagawa (Osaka Gakuin University)
Dr. TS Yeoh talked about their strategies of proliferating TRIZ in Malaysia. MyTRIZ (Malaysia TRIZ Innovation Association) was formed in 2010 and then the crucial foundation of the movement was built in the form of MOU signed by the three parties: Ministry of Higher Education (governing universities), Multimedia Development Corporation (promoting ICT as a government agency), and Intel Malaysia (well experienced in TRIZ). They agreed to cooperate in proliferating TRIZ among the nation, and to set their initial target to train university lecturers. Universities set up the training opportunities and Intel sends its TRIZ experts as trainers without charge. They have trained 1057 lecturers already as the MATRIZ Level 1 practitioners. His slide conclude with the statements: "Collaboration worked! Implementation progressing well. Ride momentum and stay focused." -- I have posted the original slides in PDF

From the Editor: General Index of this site has been revised (Jan. 9, 2013)
Toru Nakagawa (Editor, Professor Emeritus, Osaka Gakuin Univ.), Jan. 9, 2013
The present site has a powerful feature that all the articles accumulated for over 14 years are kept active with easy access. The General Index page is the key tool for the purpose. All the articles are classified into their categories and arranged in the chronological order (the latest at the top) in each (sub)category, and are accessible by one click to the individual pages. In the revision this time, the overall structure is kept as before without change but the categorization is slightly revised and is shown more clearly with the color coding of the table and in a consistent formatting. There are a number of articles which are added from missing, enhanced in the reference, moved to more appropriate subcategories, etc. The index is quite large, of 37 printed pages in English and of 30 in Japanese, and yet useful and handy for accessing articles you want.
[For example, see some old articles, such as 'Report of A Personal Trip to TRIZ Mother Countries (Russia & Belarus, Aug. 1999)' (TN, Aug. 23, 1999), 'Experiences with My Teacher G. S. Altshuller' (Phan Dung, May 8, 2001), and 'Tech Optimizer 2.5 -- Mechanism, usage and methodology learning (TN, Feb. 25, 1999). These articles are posted both in English and in Japanese.]
From the Editor: Message for the New Year 2013 (Jan. 9, 2013)
Toru Nakagawa (Editor, Professor Emeritus, Osaka Gakuin Univ.), Jan. 9, 2013
Greetings from Japan for a Happy New Year 2013! I have resigned by the end of last December from the Board and Management Members of the Japan TRIZ Society, NPO. But I still have a strong will to "develop TRIZ/USIT further and make it useful for solving problems and achieving tasks in many and different issues in Japan and in the World", and continue to be active as the Editor of the "TRIZ Home Page in Japan" as before. I wish to make this home page a 'Public site' really useful for learners and practitioners of TRIZ/USIT in collaboration with many authors and readers in Japan and in the World.

TRIZ / USIT Documents: TRIZ and USIT Solution Generation Methods -- Cross References (Dec. 22, 2012)
Toru Nakagawa (Osaka Gakuin Univ.), Dec. 19, 2012 (Posted: Dec. 22, 2012)
The present page and a set of its subsequent pages represent the cross references between the solution generation methods in TRIZ (including 40 Inventive Principles, 76 Inventive Standards, and Trends of System Evolution) and those in USIT (Sickfus' 21 Heuristics, and the USIT Operators we developed). Correspondences from individual TRIZ methods to USIT sub-operators and also from individual USIT sub-operators to TRIZ methods can be read in these pages. They are useful as the cross references in the both directions TRIZ <---> USIT. These documents were originally developed during our work for reorganizing the whole TRIZ solution generation methods into the USIT Operators, as presented in ETRIA TFC 2002 in Nov. 2002
Among them, the TRIZ --> USIT reference pages (i.e., the (0) - (4) pages shown bellow) were once posted on Apr. 3, 2003, but were withdrawn on Apr. 8, 2003 because of my mishandling of the copyrights of TRIZ references. After over 9 years, I am re-uploading them today with a revision of reference descriptions under the permissions by the relevant authors. I would like to express my sincere apologies for my mishandling and also my thanks for giving me permissions of posting to the relevant authors: Ms. Larisa & Yuna Komarcheva (the copyright owners of Mr. Genrich Altshuller's works), Dr. Yuri Salamatov, Mr. Darrell Mann, and Dr. Ed. Sickafus.

TRIZ Forum: How to Nurture and Develop Innovative Talent? (Dec. 12, 2012)
Toru Nakagawa (Osaka Gakuin Univ.), Presented at Panel Discussion of Malaysia TRIZ Conference 2012, Held by Malaysia TRIZ Innovation Association (MyTRIZ) on Nov. 6 - 9, 2012 at Penang, Malaysia.
For the panel discussion, 3 main questions were noticed before. Thus I made 5 slides for the talk; and the talk was written down in December. (Q1) How to nurture and develop creative (innovative) talent? --> 'Creative power' = 'Creativity' × 'Continuing efforts'. And 'creativity' may contain some types of attitudes, minds, capabilities, ways of thinking, etc. Different types of creativity urge different ways of nurturing. (Q2) When and how did you get interested in innovation science? --> I happened to encounter TRIZ in 1997 at a seminar. There were backgrounds for me to get interested in it. ... (Q3) Do you think school education limits the growth of students' creativity? --> It depends. Teaching a student to be creative or not is just the accumulation of positive and negative responses by the teacher (and parents and others) in various occasions of student's action and thinking for many years. ... The page is a record of my thoughts on these delicate questions.
TRIZ/USIT Paper: Creative Problem-Solving Methodologies TRIZ/USIT: Overview of My 15 Years in Research, Education, and Promotion (Dec. 12, 2012)
Toru Nakagawa (Osaka Gakuin Univ.), Keynote Lecture presented at Malaysia TRIZ Conference 2012, Held by Malaysia TRIZ Innovation Association (MyTRIZ) on Nov. 6 - 9, 2012 at Penang, Malaysia.
This Keynote is based on my paper
TRIZ/USIT Paper: Establishing and Spreading General Methodologies of Creative Problem-solving / Task-achieving: Recognition of Our New Target Obtained through a Multiple Modeling Approach (Dec. 5, 2012)
Toru Nakagawa (Osaka Gakuin Univ.), "TRIZ Home Page in Japan" paper, (Rec. Oct. 8, 2012), Published on Dec. 5, 2012.
This is a full paper written in Japanese as the extension of both the presentation at Japan TRIZ Symposium and the one at ETRIA TFC. Even though most parts overlap with the previous two presentations, the chapter of Discussions is much enhanced. It describes about the implications of the thinking approach with multiple models. The general methodology of creative problem-solving and task-achieving is a natural extension of the new paradigm of creative problem solving (i.e. the Six-box Scheme in USIT), which has been advocated by Nakagawa.

TRIZ/USIT Paper: Establishing general methodologies of creative problem-solving / task-achieving: Beyond TRIZ (Dec. 5, 2012)
Toru Nakagawa (Osaka Gakuin Univ.), Presented at ETRIA TRIZ Future Conference 2012, Held by European TRIZ Association (ETRIA) on Oct. 24-26, 2012 in Lisbon, Portugal
Here are the full paper and presentation slides written in English for publishing my recent work since last May. Full paper in HTML and in PDF
This paper puts stress on the finding that, after considering the problem of how to penetrate TRIZ into younger people (especially in Japan), we should not restrict ourselves to the framework of TRIZ but rather to establish general methodology of creative problem-solving/task-achieving and to spread it widely. Multiple models were built by viewing from different aspects and were used to proceed step by step towards deeper understanding of the problem and finding the new insight of our general target. The desirable nature and functional process of the general methodology were discussed. It is remarkable that the process used in the present study actually illustrates the process of the general methodology.

TRIZ Forum: What Should We Do for TRIZ to Penetrate into Younger People? -- Education and Training of Problem Solving with TRIZ for Younger People – (Dec. 5, 2012)
Toru Nakagawa (Osaka Gakuin Univ.), 8th TRIZ Symposium in Japan, 2012, Sept. 6, 2012, Waseda Univ., Tokyo
This is an introductory presentation as the coordinator at the Session of Special Interest Talks, in the Japan TRIZ Symposium 2012. Abstract and the presentation slides in PDF
Research Note: Towards "TRIZ for Younger People" and "Fresh TRIZ": Documents for the Future Plan of Japan TRIZ Society: (A) Slides of Models, and (B) Description (Dec. 5, 2012)
Toru Nakagawa (Osaka Gakuin Univ.), May 6, 2012 and May 12, 2012, Sent to the management members of JTS.
The motive to this work was to think over how to penetrate TRIZ to younger people, as a part of future directions and strategies for Japan TRIZ Society and also a plan of the Japan TRIZ Symposium 2012. Starting on May 1, I made 26 slides (including several reused ones) and a document to explain them by May 6. I sent the slides and the document via email to the management members and education group members of Japan TRIZ Society (about 30 people in total) on May 6. Several of the colleagues replied to me positively. Adding 6 more slides and their description, I sent the enhanced materials to the same members on May 12. In the present page (in Japanese), the whole document of 32 slides
First I built the models (or diagrams) of internal (mental and intellectual) steps for a (young) person to learn and accept a creativity method like TRIZ, viewing from different perspectives. Another model shows the relationships between the company's activities for introducing TRIZ and the personal intellectual growth of a TRIZ leader/practitioner. Then, TRIZ promotion activities of various promoters in Japan are depicted first individually and then in a merged model. Then, I went ahead to build a model of areas and issues where TRIZ can/should be applied. The model suggested that to such a wide range of problems and tasks we should apply not the individual tools and techniques of TRIZ (or the TRIZ method) but more generally creative thinking and general methods of creative problem solving. This finding has guided me to the statement of our new general target, i.e.,
"To establish a methodology of creative problem-solving / task-achieving, to spread it widely, and to apply it to problem-solving and task-achieving jobs in various domains in the whole country (and the world)"
I further went ahead to build a conceptual model of activities necessary for establishing such a general method, and also the models of the general method of creative problem-solving and task-achieving. -- Thus the present document written in May contains most of the aspects of my later publications.
Research Note (Guide): From "How to penetrate TRIZ into younger people?" to the new target "Establishing general methodologies for creative problem solving/ task achieving": From May to November, 2012 (Dec. 5, 2012)
Toru Nakagawa (Osaka Gakuin Univ.), Nov. 27, 2012 (English translation on Dec. 3, 2012).
This page intends to be a guide to my several related works done for these 7 months from May to November, and posted together on Dec. 5. They contain original documents shown to a group of people (in Japanese), conference presentations (slides and papers) (in Japanese and in English), and a paper published here for the first time (in Japanese). I feel that these works have made an significant step, i.e. "beyond TRIZ", in my understanding of creative problem-solving methodology.

A brief report, written for the management members of JTS on Nov. 12, is posted in the Japanese page with minor modification. A very impressive event consisting of Conference, Workshop, and Competition. Held by MyTRIZ (Malaysia TRIZ Innovation Association), with the support of 2 Government Ministries, MDeC (a national agency in the field of ICT), Intel Malaysia, Univ. Science Malaysia, etc. A strategic 3-party agreement was made in 2010 among Intel Malaysia, Malaysian government, and Malaysian universities: 'Training of TRIZ to university lecturers are promoted by university's setting up, Intel's providing with its TRIZ experts without charge, and government encouragement. Then the lecturers teach TRIZ to students.' On the basis of this strategy, the Competition was carried out with the entree of 27 teams from various universities. MyTRIZ has about 50 members from industry and about 200 from universities.
Conference had interesting invited talks both on industrial promotion/application and on teaching at universities and for children. 6 Keynote speakers were invited from abroad, and TRIZ pioneers in Malaysia gave very good presentations. Proceedings were not prepared beforehand. When the presentation slides are posted in their Web, I wish to introduce several of the presentations in this site as well. [Nakagawa's Keynote

On the 14th Anniversary of "TRIZ Home Page in Japan": Toru Nakagawa (Nov. 15, 2012)
This Web site "TRIZ Home Page in Japan" celebrates on Nov. 1 its 14th Anniversary together with readers in Japan and over the world. This site is to promote the understanding and real usage of TRIZ by openly publishing information and communications related to TRIZ on a not-for-profit basis. Though I have been operating this site as a volunteer, this site is not a personal site but a public forum to be composed of the contributions by readers, as you see already. Most pages are published in Japanese and in English in parallel for the purpose of mutual understanding and collaboration between Japanese and overseas TRIZ learners/practitioners. I envisage that Pubic Web Sites built in different TRIZ Communities will form A Global TRIZ Community with much reduced language barriers

TRIZ Forum: Necessity of more 'Tsukuri (Creation)' in Education in Japan in contrast to the currently overweighed 'Manabi (Learning)' (Jul. 3, 2012)
Kenichi Yumino (Professor Emeritus, Shizuoka Univ.), in "New Year Free Discussion with Professor Onda (Jan. 2011)", Japan Creativity Society, Jun. 2011. (Excerpt under the permission.)
Nakagawa happened to read the pamphlet again last April and was impressed much with Prof. Yumino's talk: "In education in Japan, 'Learning (Manabi)' has been the strong tradition in contrast to 'Creation (Tsukuri)'. 'Learning' assumes the texts or teachers are correct, and students should learn, understand, and use them. 'Creation' needs for the students to think, express, and make something new and original. Such new things usually include errors/failures. Only after the students correct errors again and again, they can achieve something new and valuatable. Such a process of errors for creation should be praised and taught in schools and universities. ..." This article was a trigger for us to invite Professor Yumino to give a Special Invited Lecture at our coming TRIZ Symposium on "Educating Creativity: Making the foundation for disseminating creation techniques".
TRIZ News: The CIL Journal (a Next Generation of the TRIZ Journal) (Jun. 4, 2012)

From the Editor: Message: On Retiring Osaka Gakuin University (Apr. 9, 2012)
Toru Nakagawa (Professor Emeritus, Osaka Gakuin University), Apr. 6, 2012.
I have retired Osaka Gakuin University by the end of March at the fixed age (plus 1). During these 14 years while I was working at Faculty of Informatics of OGU (and even during many more years while I was a student, and was working for the University of Tokyo and later for Fujitsu Limited), I have been owing much to you among many others for your kind support and collaboration. I am sincerely grateful to you all.
On the retirement, Osaka Gakuin University has given me the title of Professor Emeritus of OGU, and has allowed me to use my OGU email address permanently and kindly further to continue the operation of "TRIZ Home Page in Japan" in the OGU Web site. In addition, on a voluntary basis, I am going to continue my work as one of the Board Members of Japan TRIZ Society, NPO, and as the Program Chairperson of TRIZ Symposium in Japan to be held by JTS. Thus I am going to continue my TRIZ/USIT activities in a way almost same as before.

Toru Nakagawa (Osaka Gakuin University), Mar. 30, 2012.
Last February 20-27, I visited Iran and presented a Keynote and a research paper at the PSST 2012 Conference held in Tehran on Feb. 22-23. This was my first trip to Iran, and I accompanied my wife Masako. We were warmly accepted by the Iranian group of TRIZ promoters and enjoyed much in Tehran and the old capital Isfahan. In contrast to our previous images of Iran formed through newspapers and TVs in Japan, I have found different faces of the country and its people. Thus, I am reporting my personal experiences and impressions during the visit, along with some pictures. The page is composed of: History of communications with Iranian TRIZ group since 2006, Decision of the visit, Trip outline, Report of PSST 2012 Conference, About the TRIZ promoting group in Iran, Experiences and impressions in Iran. --- English page is now posted (Apr. 9, 2012).

(Added: Apr. 9, 2012) many others. Mar.- Apr. 2012.
Last January and recently in March, I have received a number of messages from my readers and TRIZ colleagues. I would like to post some of them here, either in the English page or in the Japanese page, with sincere thanks.
TRIZ/USIT Paper: Creative Problem-Solving Methodologies TRIZ/USIT: Overview of My 14 Years in Research, Education, and Promotion (Mar. 13, 2012), (Mar. 23, 2012)
Toru Nakagawa (Osaka Gakuin Unversity), Jan. 6, 2012, To be published in "The Bulletin of the Cultural and Natural Sciences in Osaka Gakuin University", No. 64, March 2012; Posted in "TRIZ Home Page in Japan" in Japanese, on Mar. 13, 2012; English translation: March 22, 2012.
This article is an overview of my activities for the 14 years (from Apr. 1998 to Mar. 2012) while I have been working for Osaka Gakuin University. On retiring the University by the end of March at the preset age (70) (+ 1 extra), I wrote it for a Bulletin of OGU, and under the permission of the Bulletin I am posting it here in my Web site in Japanese and in English translation. PDF
"The core of my working activities has been the research on TRIZ ('Theory of Inventive Problem Solving') and USIT ('Unified Structured Inventive Thinking'). I have attended and presented at international conferences on TRIZ every year, and extended USIT (i.e. a unified and simplified TRIZ) further to find a new paradigm called 'Six-Box Scheme' for creative problem solving. In the field of education, besides several other classes on ordinary information science, I have been teaching on this theme in a lecture class and also in 3rd and 4th year seminars, where my students and I have made several successful case studies of solving familiar problems.
On the basis of these research and education, I have been working for the promotion of penetration of TRIZ and USIT. I established a public Web site "TRIZ Home Page in Japan" and have been operating it for these 13 years. Founding and joining the Japan TRIZ Society, we have held 'TRIZ Symposium in Japan' annually. With further development and wider penetration, the methodologies of creative problem solving will support the movement of technological innovation and will cultivate human resources having the capability of creative thinking, I hope."I would like to express my sincere thanks to all the people who have been supporting me for these years.
Even after my formal retirement, Osaka Gakuin University will kindly contiue to support me operating this "TRIZ Home Page in Japan" and using my email address at OGU just as before. I wish to keep my activities going on as long as my health allows me.

The Author is a student of Nakagawa's two classes; Seminar IIA on "A variety of Input devices and methods -- Learning the evolution of technologies" and Lecture class on "Methodologies for creative problem solving". He has chosen the report theme for himself and has written an excellent survey report. He surveys the current status and near future of automobile safety technologies by referring to home pages of various makers, and interpret such technologies in terms of 40 Principles of TRIZ. He also suggests a proposal of temporary floating behavior on water in case of some emergencies. I was amazed with this report and am happy to post it here in my Web site.

[4] Umakant Mishra: "TRIZ Principles for Information Technology", Japanese Edition, Supervising translator: T. Nakagawa, Jan. 2012 (CD-R Edition)
[5] Darrell Mann: "Matrix 2010", Japanese Edition, Translated by T. Nakagawa, Feb. 2012
TRIZ Books (Announcement of Publication): Japanese Edition of Darrell Mann: "Matrix 2010" -- Publication Announcement (Plan) (Jan. 22, 2012)
Translated by Toru Nakagawa (OGU), (to be) Published by Sozo Kaihatsu Initiative (SKI), Feb. 2012 (plan)
In 2000, Darrell Mann and Simon Dewulf (CREAX) initiated a big research project of analyzing all the US patents granted since 1985 for revising TRIZ knowledge bases. One of their results was "Matrix 2003" which was an entire update of the Altshuller's Contradiction Matrix. Darrell Mann (Systematic Innovation) has kept the project's activities and recently published an up-to-date edition "Matrix 2010", for maintaining higher-than-90% appropriateness of the Inventive Principles suggested by the Matrix. He says they have analyzed more than 3 million patents so far. The number of parameters has increased from 39 to 48 to 50, and the number of suggested principles in each cell is now up to 9 in comparison to max 4 in the original Matrix. Once you understand the great vision of Contradiction Matrix by Altshuller, why don't you utilize its up-to-date edition "Matrix 2010".
