Editor's Note (Toru Nakagawa, Jul. 10, 2019)

Last year in March and April, I carried out a pilot project to build a Catalog of TRIZ-related Sites located in Japan.  I posted the Catalog of 92 sites first in Japanese , and then in English translation .  We should note that the Catalogs (even written in English) are for the people in Japan, and not so appropriate for the people in the whole world.

In the present page, I re-evaluated all the 92 sites from the viewpoints of the people in the world.  Namely, for showing the Japan part of the World WTSP Catalogs.  The main criteria are: (a) the usefulness/importance (including originality, uniqueness, contributions, etc) of the site from the global standard,  (b) Representative and frequently-used sites in Japan (even written only in Japanese), (c) Reliable/important sites in Japan in the areas in and around TRIZ.  

The sites which are evaluated as either ◎ Most important, ○ Important, or □ Worthy of World Catalog are to be included in the World WTSP Catalogs as the parts from Japan.   The Japan WTSP Catalogs, on the other hand, are composed of these sites and the sites evaluated as △ Worthy of Country Catalog.  For showing this point clearly, the ◎○□ sites are shown first, separating from the △ sites.  The sites are rearranged, but the site numbers are kept same as in the former manuscript .

This page is composed of the following 5 parts:

(1) Index Table of Sites for the World WTSP Catalogs (Japan part) ( ◎○□) ,  TRIZ sites and sited Around TRIZ

(2) Sites Descriptions for the World WTSP Catalogs (Japan part) ( ◎○□) ,  TRIZ sites 
(3) Sites Descriptions for the World WTSP Catalogs (Japan part) ( ◎○□),  sites Around TRIZ

(4) Sites Descriptions for the Japan WTSP Catalogs ( △) ,  TRIZ sites 
(5) Sites Descriptions for the Japan WTSP Catalogs ( △) ,  sites Around TRIZ

This page demonstrates the examples of manuscripts to be prepared by WTSP Teams in various countries. 

The parts (1)(2)(3) form the Japan part of the World WTSP Catalogs.  Namely:

Part (1) corresponds to the Index Page of the WTSP Catalog, while Part (2) and (3) corresppond to the Descriptions of Sites (◎○□).
By clicking the Site Code (i.e. the site number at the leftmost column) of the Index, you can see the Descrption of the Site.

(Note: In the actual WTSP Catalogs, the Index page and the 'Descriptions of Sites' pages will be in separate HTML pages.  But in the present case, they are shown in one HTML page for easier understanding of the Catalog structure.)


Editor's Note (Toru Nakagawa, Mar. 16; Apr. 3; Apr. 24, 2018)

In the Japanese page, a full manuscript for the Catalog of TRIZ-related Sites in Japan has been posted, as a preliminary part of the WTSP World Catalog.  It introduces 92 sites, describing in 2 to 8 lines each.  Almost all the sites are posted in Japanese only. 

In the present English page, I temporarily show 25 important sites in Japan with annotation.  Please give me some more time for preparing the English version.

Short introduction to the Japanese page (Editor's Note, Toru Nakagawa Mar. 15; Apr. 3; Apr. 22, 2018).

This Catalog of TRIZ-related Sites in Japan has been prepared as a part of the World TRIZ Sites Project (WTSP), in the following process and policy.

(1) It aims to introduce TRIZ-related sites in Japan, by searching as widely as possible. Internet search with Yahoo! using 'TRIZ' as the keyword is the basic means, and many more sites are added later.

(2) The sites are classified with their types/nature into the following categories.   Number of sites currently described is shown in ( ).

(a) TRIZ-related Information Sending Sites (i.e., important sites having some nature of (b) to (h))  -- (24 sites)
(b) Consultants/Venders/Dealers in TRIZ  -- (12 sites)
(c) Academic societies, associations, journals, etc. in TRIZ-related areas   -- (17 sites)
(d) Universities, public organizations, not-for-profit organizations, etc.  -- (13 sites)
(e) Commercial/non-commercial organizations operating lectures, seminars, distant education, etc. in the TRIZ-related fields  -- (3 sites)
(f) Technical dictionaries, book search, technological news, communities, etc. in TRIZ-related areas   -- (8 sites)
(g) Personal sites, blog sites, and other non-TRIZ sites which post some TRIZ-related articles   -- (14)
(h) Personal sites, blog sites, and other non-TRIZ sites which are useful for TRIZ even though the site do not post TRIZ articles  -- (0 sites)

(3) Each site is introduced concerning to its nature, special features, useful information for readers, etc. 

(4) Main page of each site is shown with URL and a hyperlink.  Searching for TRIZ pages inside each site is also shown with a hyperlink .

(5) Further enhancements and revisions are desired.  Proposals of addition, revision, updating, etc. by any person (especially by the site owners) are welcome. Much enhanced introduction is desirable for the sites with the  mark.

(6) Detailed description of many Japanese sites (just like in the Japanese page) is useful and important for Japanese people, but rather concise description of important sites only should be useful for most people in the world who do not read Japanese. Thus, in the Regional/Global editions of the WTSP catalog, only some selected Web sites will be included.  The sites in the category (a) are the candidates for such a purpose. [TN, Apr. 3, 2018]

(7) Thus in this English page, the 24 selected sites in category (a) are introduced with full annotation and additional 68 sites in categories (b)-(h) in a shorter form of annotation. [TN, Apr. 24, 2018]

◎ JP-01   TRIZ Home Page in Japan (Editor: Toru Nakagaw) (in Japanese)  (in English)      Location jp   Language  en, jp  Roles (a2) Public Web site, (e1) Method developer 

Editor: Toru Nakagawa (Professor (1998-2012)/Professor Emeritus (2012- ) of Osaka Gakuin University).  He established this site in Nov. 1998 (Nov. 1 in Japanese and Nov. 15 in English), and has been posting new TRIZ-related information actively with unfixed interval of 2 to 4 weeks constantly till present.

The site posts introductory articles, overviews, papers, conference reports, etc. on TRIZ with a wider scope.  Pages in Japanese and pages in English are posted more or less in parallel.  The articles/papers are written not only by the Editor (in Japanese and in English), but also by many Japanese authors (in Japanese and some in English translation) and by many overseas authors (in Japanese translation and some in English).  It has four 'Entrance Pages' adapted for four types of readers (i.e., for Children and high school students, for Students and the general public, for Engineers and researchers novice to TRIZ, and for Practitioners and experts of TRIZ); they show categorized lists of (pretty many) recommended pages with annotation.

The Editor's research themes have evolved from (a) introduction and proliferation of (classical and modernized) TRIZ, to (b) introduction and extension of USIT (Unified Structured Inventive Thinking), (c) proposal of Generalized Methodology for Creative Problem Solving (CrePS), and (d) Research on the Principal Contradiction ('Liberty vs. Love') of Human Culture.

○ JP-03 (a) (c)  JTS (Japan TRIZ Society (NPO)) (in Japanese) (in English)    Location jp   Language  jp, en  Roles  (b1) Dedicated association 

Japan TRIZ Society is the nation-wide Center for promoting and proliferating TRIZ in Japan, established officially in December 2007 on the basis of Japan TRIZ CB.

It has organized TRIZ Symposium in Japan every year (from the Fourth in 2008 to the Thirteenth in 2017).  The Symposium till 2012 was held for 3 days with actively calling for participation/presentation by overseas people, but later since 2013 it was held for 2 days and with mostly-domestic participation/presentation except invited Keynote speakers from abroad.  Every year many user industries gave their presentations on TRIZ usage and promotion.  (Almost) all the presentations were shown with slides in Japanese and in English in parallel.   Keynote Lectures and Award-winning presentations (about 5 papers every year, voted by the participants) are publicly posted in the Web site about 3 months later, and all other presentations are posted in the 'Members only' pages of the site. 

The short TRIZ introduction article in this HP is rather poor unfortunately, I think.  In Japan TRIZ Society, four study groups are running for several years.

○ JP-09  IDEA Corp. (Mamoru Zenko) (in Japanese)       Location jp   Language  jp  Roles  (e4) Consultants

IDEA is a consulting firm specialized in TRIZ, starting in 2003 by spinning off from ITEQ, and has been actively conducting trainings and consulting in industries and open seminars.  IDEA has particular strength in applying QFD-TRIZ-TM in an integrated manner to new product development, and in consulting with big and SME companies in such a strategy.

The Web site explains to use the following four IDEA-style scientific development methods in an integrated way: Seeds-driven Quality Deployment (SDCD, for developing new business fields), IDEA-QFD (for developing new products in existing business fields), IDEA-TRIZ (for innovative problem solving with break-through solutions), and IDEA-TM (for implementing new solutions optimally).  Various documents of these TRIZ-related methods are downloadable free of charge (with registration).  IDEA also sells TechOptimizer and Goldfire Innovator of Invention Machine (later under IHS) as a dealer and promotes the use of software tools together with their methods. 

At Japan TRIZ Symposia, several industrial customer companies reported their successful results of promoting/applying IDEA ways in their new product development, confirming the effectiveness of IDEA’s methods and consulting.  

The following two blog sites were operated several years ago, but have not been updated recently:

○□ JP-10 MOST LLC (Kazuya Yamaguchi)  (in Japanese)     Location jp   Language  jp  Roles  (e4) Consultants

Since 2001 Kazuya Yamaguchi led the innovation of development process and quality management in Kyushu Matsushita Electric Co. (renamed into Panasonic Communications Co. (PCC) in 2003) by using scientific methods including quality engineering, TRIZ, and QFD.  He retired from PCC in 2007 and started a consulting firm, MOST LLC, together with his several colleagues who worked together for the PCC process innovation.

MOST's philosophy is “To propose and provide methods for drastic innovation applicable in the era of AI (Artificial Intelligence, e.g., IoT and Factory big data)”.  More specifically it proposes "to use scientific technology tools in the world (e.g., QFD, TRIZ, Quality engineering (or TM), MATLAB, and some other universal-use tools) effectively, to improve the current styles of research, development, design, and manufacturing into new business promotion styles with high efficiency, and to put your business on a sustainable and growing curve by obtaining maximal results in achievements."

Their methods are written closely by the MOST members in their books (or white papers), which are available in their HP with free downloading (without registration).  They include:
(1) "Improve your quality, then your costs get reduced (recommendations to Taguchi Method)" by Kazuya Yamaguchi (95 pages).
(2) "How to eliminate the needs of remaking software in the market due to bugs (recommendations to Taguchi Method)" by Kazuya Yamaguchi (27 pages).
(3) "We can design without remaking! (Parameter design in Taguchi Method)" by Ikuro Hamada (59 pages).
(4) "Method to realize No. 1/only-one products easily (TRIZ)" by Kiyoaki Matsui (28 pages). 
(5) "Method to develop epoch-making products easily (QFD-TRIZ-TM and Technology and IP strategies)" by Kazuya Yamaguchi (42 pages).
(6) "Method to achieve visual inspection drastically efficiently (MATLAB and TM)" by Ken-ichi Kawano (30 pages).
(7) "Method to achieve acoustic inspection drastically efficiently (MATLAB and TM)" by Ken-ichi Kawano (30 pages).
(8) "Business strategy for executives to raise their performance surely (Raising performance/results come from raising members)" by Kazuya Yamaguchi (31 pages).
All these textbooks are impressive with their strong encouraging messages.

○ JP-12  Ideation Japan, Inc. (Teruyuki Kamimura)  (in Japanese)       Location jp   Language  jp  Roles (e4) Consultants, (e5) Training organizations

Ideation Japan was raised by Teruyuki Kamimura, a patent attorney, in 2010 and currently is the only agency of International Ideation Inc. (USA) in Japan. 

In Ideation International, TRIZ Masters (and collaborators of G. Altshuller since 1970s) Boris Zlotin, Alla Zusman, et al. developed TRIZ further in depth to form a new and big system named Ideation-TRIZ (or I-TRIZ).  The system is composed of 3 main components, i.e., Inventive Problem Solving (IPS), Anticipatory Failure Determination (AFD), and Directed Evolution (DE).  Such methods are supported by software tools which install well-systematized solution prototypes (called System Operators).

The HP of Ideation Japan posts many introductory articles on these methods in a way easy to understand.  Multiple issues of pamphlets are downloadable (free of charge, with registration), and videos of an introductory seminar (14 parts, over 3 hours in total) can be seen free of charge (without registration).  Ideation Japan conducts seminars on I-TRIZ and its software tools pretty frequently (with or without charge) as a part of its active proliferation activities.

In 2013 it established 'I-TRIZ Promotion Association' for the purpose of promoting their private I-TRIZ certification.

○ JP-14  TRIZ Study (Shinsuke Kurosawa) (in Japanese) (in English, List of Contents in their original languages)  Location jp   Language  jp, en  Roles (a1) Dedicated for information sending

This site intends to be a Web site for the people who want to study TRIZ deeply in the Japanese language.  The site owner is Shinsuke Kurosawa, formerly at SANNO Institute of Management.  He is very fluent in Russian and has been working to study and proliferate TRIZ since mid-1990s. 

This site is of special importance in Japan in the points that many original TRIZ papers written by G. Altshuller are posted in Japanese directly translated from Russian.  He also posts Japanese translation of various documents authorized by MATRIZ (i.e., International TRIZ Association), e.g., TRIZ Textbook for MATRIZ Level 1 certification, TRIZ Body of Knowledge (BOK), etc.  Besides them he introduces a number of papers on modern TRIZ in Russia, especially those related to education with TRIZ.

A wonderful article in this site for introduction to TRIZ is the instructions and worksheets of "16 steps in TRIZ for you to use today (for solving your problems)", which he has originally written down concisely.  As the process for solving problems, he shows the sequential points of focus in 6 main steps (i.e., problem/task/ideality, situations/viewpoints, inventive principles, resources, strategies/contradictions, and action plan) having 16 sub-steps in total.  For each sub-step, he shows in a worksheet the questions to think, and in the text in parallel he describes the instructions, simple examples, and a consistent set of case study.  The process is so simple and yet powerful that engineers novice to TRIZ may be able to work with it for him/herself even today.

○ JP-18 (Osamu Kumasaka)  (in Japanese)         Location jp   Language  jp  Roles  (e7) Networking/Matching organizations

This is a nice portal site which has produced and implemented a mechanism for connecting (a) Issues in monodukuri (or manufacturing in general) (and the industries having them) with (b) Methods useful for solving the issues (and the professionals in such methods).  The basis of this mechanism is the 'Monodukuri Engineering Matrix' which Osamu Kumasaka built during his R&D work for Pioneer Corp.  The Matrix has rows of 60 Issues for monodukuri (i.e., Planning 7, Development & design 15, Manufacturing 22, and Quality in market 6) and columns of 118 Methods for solutions (including Strategy techniques 9, TRIZ 8, USIT 1, Quality engineering 8, etc.).  In the Matrix cells, applicability and usefulness of the method for the issue is shown with the 4-grade evaluation (i.e., 3, 2, 1, and 0).

Kumasaka started this site in 2012 after his retirement.   First he obtained supports and registrations by many professionals (currently 138), and obtained their contributions of introductory articles on individual methods and their usage (currently 1600 articles, 2-3 pages each), training texts (currently 490 documents), and application case studies (currently 950 cases), for publicly posting in the site.  Users (in industries) may choose an issue most relevant to his/her problem from the list of 60 Issues, then is led by the Matrix to possibly applicable/useful methods, and can further study the methods closely by reading their introductions and case studies.  If a user asks a question (or raise his/her own issue) openly at the site, any professionals may reply to it openly at the site as well. 

All these basic use of the site is free of charge for the users (some of them need registration without charge), while there are additional services of seminars and individual consultation with charge.  The site is now operated with annual support money and payback for consulting arrangement from the registered professionals.  Professionals seem to find merits in the site for paying such money.  Recently, the site started a service by professionals to support SMEs for their applications to governmental grants.

Because of the accumulation of useful information and appropriate operation mechanism, this portal site is now growing steadily year after year.  This is certainly a significant business model started by Osamu Kumasaka.

□ JP-02  (Former) Japan TRIZ CB (Collaborative Board of TRIZ Promoters and Users in Japan)  (in Japanese) (in English)    Location jp   Language  jp, en  Roles (b1) Dedicated association

The first nation-wide organization for promoting TRIZ in Japan, established in 2005, by the collaboration of TRIZ users and promoters. Japan TRIZ CB organized TRIZ Symposium in Japan (First in 2005 till Third in 2007). The Web site posted the records and presentations in these Symposia. At the end of 2007, the organization turned officially into Japan TRIZ Society (NPO) (see elsewhere). The Web pages are still active inside "TRIZ Home Page in Japan".

□ JP-07  Cybernet Systems Co., Ltd.    (in Japanese) (in English) (only partial)    Location jp   Language  jp  Roles  (e3) Dealers

General Agency in Japan of Invention Machine Corp. (USA) since 2007.  The company is promoting the sales of the software tool, Goldfire Innovator (the successor of TechOptimizer), and conducting seminars on it.  Goldfire Innovator is capable to access to a huge body of information sources (not limited to patent DBs) in science and technology with its powerful semantic analysis tools, and hence to conduct surveys and knowledge sharing/management in a much wider scope than ordinary TRIZ techniques for problem solving.  In 2012 Invention Machine was merged into IHS (USA) with the hope to utilize even wider information sources in the world.

The Web site of Cybernet Systems posts introductions to the functions and usage of Goldfire, monthly articles on 'What can you do with Goldfire?', and user supporting information, etc.  Inviting many user industries, Cybernet Systems held Invention Machine User Conference annually in 2009 to 2011 and Goldfire Innovation Forums annually in 2013 to 2017.

□ JP-16   Pro-Engineers (Shigeru Kasuya) (in Japanese)   Location jp   Language  jp  Roles (e4) Consultants, (g3) Knowledge sharing

Shigeru Kasuya worked for SONY and later for Fuji Xerox, and started his consulting firm 'Pro-Engineer' in 2006.  His site states its purpose as "TRIZ & Support for Differentiating Technology Development".  He intends to support not only the usage of TRIZ but also more widely the development of new technologies/products, innovation in business processes, human resource development of researchers and engineers, etc. 

The top page of his Web site is a tightly packed index to a lot of information in the site.  There are interesting articles such as abstract documents of his various seminars, articles in newspapers and journals mentioning about his work, his answers to questions/issues raised by various industry users (over 40 articles, which are posted also in the Q&A corner of,).  He also shows his own examples for 40 Inventive principles; they include illustrated examples for all the 104 sub-principles, examples from the areas of IT/SW, chemistry, and biology. 

Contradiction Matrix (in the classical form) is also installed in the HP so that the inputs of an improving parameter and a worsening parameter return the outputs of four inventive principles.  He writes an interesting suggestion that a simple Google search with a keyword of target object and a second keyword of function/property can give the information very similar to the results from TRIZ Effects database.  At the end of the site, several case studies of solving problems with TRIZ are demonstrated.  This is an interesting site giving us a lot of new suggestions.

□ JP-17   IdeaPlant (Rikie Ishii) (in Japanese)  , Rikie Ishii's Activity Report (in Japanese)  , (in English) (only partly)   Location jp   Language  jp  Roles (e4) Consultants, (e2) Software/tool developers

IdeaPlant was a name of a group organized by Rikie Ishii in 2005 in Sendai, with the intention of 'a place for growing seeds of ideas into large trees'. (The group seems to have worked in the name of 'Miyagi TRIZ Study Group' for a certain time.)  Ishii made the IdeaPlant as a business in 2009.

He has been working energetically for raising creative persons and creative organizations, mostly by devising/practicing/proliferating the methods/processes/tools for enhancing the idea generation.  He has produced 'TRIZ Brainstorming Cards' (i.e., playing cards with simplified phrases and illustrations of TRIZ 40 Principles), 'BreStir' (i.e., a playing process for enjoying and activating the Brain Storming using some specialized cards), among others.

He conducts many 'Workshops for enhancing idea generation' at various industries, universities, high schools, local communities, etc., getting high reputation on his vivid way of workshops. His activities at various places in Japan (and some in neighboring countries) are reported frequently in his blog "Activity Reports by Rikie Ishii".  He also actively uses various IT media such as Facebook, Twitter, YouTube, SlideShare, etc.  We can learn his way of workshops and idea generation through his presentation slides, "Techniques for creative idea generation" at his 5-hour mini-lecture and workshop held in Kyoto in February 2018. .  His presentation is always attractive with his illustrations and good design sense.

Akihiro Katahira started to build this site in 2013 and has been developing it further till present.  He understands that the act of Thinking is the repetition of two phases, i.e., 'Thinking out' (to get an idea useful for him/herself) and 'Evaluation and decision'.  Then in this Web site Katahira is trying to figure out 'What should we do to Think out better and more effectively?'.  

He posts many interesting working papers on 'How to Think out' according to his own thoughts and in his own terms.  Recently he developed and published a software tool of 'Fuda-Yose method', which allows to handle many labels (on which any keywords, short sentences, or figures are written) to move them around in various arrangements on the Excel window for stimulating users to think out.  The Fuda-Yose Tool is also introduced in "TRIZ Home Page in Japan" together with a number of application examples.

△ 20 (a) (c)  SlideShare (in Japanese/English/any other languages)     

SlideShare is a world-wide Web service which allows to contribute any presentation slide file (in the formats of PowerPoint, Word, PDF, etc.) for posting without charge publicly to all the people in the world.  SlideShare is operated by LinkedIn, an SNS mostly for business/professional persons.  Main themes of SlideShare are business, creativity, and technologies, but not limited to them.  It has posted over 16,000 presentations in total already, it says.

On the topics of TRIZ, in Japanese, Rikie Ishii and Ideation Japan have posted each several tens of presentations.  Many more presentations related to TRIZ are posted in English and in other languages.  Users can read and download any presentation without charge.  This seems to be an important and rapidly growing information source.

This is a well-known popular site accepting to post any category of videos publicly.  It has accumulated a huge number of videos already and is accepting many more videos daily and attracts a gigantic number of viewers daily from all over the world.

When I searched for videos with the keyword TRIZ inside YouTube, an unlimited number of videos appeared (so I quitted at 400 videos).  Videos in relation to TRIZ are only few in Japanese, but many in English and in other languages.  Video lectures by G. Altshuller himself and by many famous TRIZ leaders in the world are found and viewable freely.  This is a convenient and powerful information source, but you should better find elsewhere a good article mentioning a good TRIZ video in YouTube and get its URL to access the video.

△ 22 (a) (f)  Wikipedia (in Japanese)      

Wikipedia is a 'Free Encyclopedia' which is used very often by ordinary people not specialized in each subject.  Individual pages (or subjects) in Wikipedia are written by any voluntary people and revised many times by many people to improve the descriptions; thus Wikipedia is usually supposed to be a reliable information source.  Unfortunately, however, in the case of TRIZ, such voluntary, collaborative work seems not working well at present (especially so in its Japanese edition).  This is probably because of the complexity of the TRIZ system and the diversity of opinions/understanding by different TRIZ leaders.

Current Japanese edition of 'TRIZ' page in Wikipedia describes, besides a very short general introduction, that the catch-phrase of 'Super-Inventive Technique' used in the initial stage of TRIZ introduction in Japan was misleading, and it lists 40 Inventive Principles with very short explanations.
At moment, the description of TRIZ in Wikipedia (in Japanese) is not recommendable.  Please refer various introductions and articles posted publicly as listed in the present WTSP catalog of TRIZ-related sites.
