Message (Toru Nakagawa, Jan. 3, 2021)

On the start of New Year 2021, I wish you all the year be healthy, happy, successful, and the World be peaceful and recovering from the pandemic.

The following is my New Year Card to my friends in Japan whom I met before my TRIZ days.

I wish to send you the message in English translation, because the world is under the severe Covid-19 pandemic situations, more or less similarly. 


For the Coming Spring                   Hoping ever lasting friendship with you !


2020:   Cherry blossom in a park under the Covid-19 pandemic regulations   2021:  Praying for the spring to come with our new hope in the world !


The World TRIZ-related Sites Project (WTSP) has built the β Edition of the World WTSP Catalogs after the efforts for these 3 years.  Conferences in last autumn were carried out online, so we fortunately gave our WTSP presentations in 5 TRIZ-related conferences all over the world, i.e., in Russia, USA, Romania, Taiwan, and Japan, during about one month.  We are going to enhance the World WTSP Catalogs further this year.

In the period of serious global crisis triggered by the Covid-19 pandemic, I am learning Darrell Mann's recent papers and books giving us much insights.  I have started to introduce them in Japanese translation and to publish them in near future. 

I wish you, your family, and people in your country good health, happiness, and good work in the new year !
