[1] From the Editor: Message for the New Year 2017

                         (Toru Nakagawa)

   Greetings from Japan for a Happy New Year 2017!!

   Wish the year be peaceful in the World, and healthy, happy, and successful for you all.

Posted is an English translation of my New Year Card which I sent to about 200 friends in Japan whom I met before my TRIZ days.


Happy New Year 2017 !!

Since my retirement of OGU in 2012, I am continuing my research and proliferation activities on the methodologies of creative problem solving.  

I have reached a conviction that the Six-Box Scheme is the new paradigm of creative problem solving in general, including technological development in industries, advanced research in academia, issues of social problems, etc.

Starting with the visualization of the logic of "The Low-living Elderly" book written by Takanori Fujita, I worked on the issue of poverty in the Japanese society.

In the issues of poverty and welfare, there always exist the conflicts of arguments between self-responsibility and mutual help.  

At the root of them, I have found the conflicts between the two basic Principles, i.e., Liberty and Love.

Liberty vs. Love is the Principal Contradiction inherent in the Human Culture, and emerges and exists everywhere unsolved in the history.  

Ethics, containing the Fundamental Human Rights (having Equality at its core), can motivate and coordinate Liberty and Love together.

Thus at the personal (and inter-personal) level and at various social levels, the relationships among Liberty, Love, and Ethics should be revealed in their actual as well as desirable situations.

And such understanding should be shared widely as the Human Culture.

--- This is the understanding of the problem and its hypothesis I have just obtained at the age of 76, and it forms an important starting point for the big task of creative problem solving.

I wish you all for your health and success, and for a peaceful new year.

In the Japanese page, I wrote a summary of my work in 2016 and a brief message of my thought about the situations in Japan and in the world, especially quoting the one I wrote last July after the election of Japanese Parliament.

[2] Introductory: 'Liberty vs. Love':

   The Principal Contradiction Inherent throughout the Human Culture

                      (Toru Nakagawa)

This article was written last October and published in the Bulletin of YMCA at Univ. of Tokyo last December.

Starting with my self-introduction, I briefly trace my work for these 20 years on methodology of creative problem solving, and explain the big topic in the title on which I have been working since last year.

I explain how I have been working as a researcher, initially in physical chemistry and later in informatics, to understand and develop 'Methodology of creative problem solving' (namely, methodology of research and development).

I found the Six-Box Scheme as a new paradigm in science and technology.  

For extending its application to social problems, I chose to work on the problems of poverty in the Japanese society. Underlying people's arguments whether to help the poor, I found the conflict between the emphasis on Liberty and that of Love.  

Then I realized that Liberty vs. Love is much more basic, and actually is the Principal Contradiction unsolved throughout the history of Human Culture.  

I have shown here a hypothesis of the Liberty vs. Love Contradiction in its skeletal form.

The idea that there exists a basic conflict (or contradiction) between Liberty and Love is not difficult to understand in itself. You can easily show such examples in our everyday life, in our society, and in the international politics, etc.

We have been taught simply, however, "Liberty and Love are both important. So you should respect both of them. They should be compatible."

Nobody dared to say clearly "Between Liberty and Love there exists an intrinsic conflict. That is the most basic, Principal Contradiction of Human Culture."

The present approach is based the spirit/philosophy of TRIZ, i.e., "Understanding contradictions clearly is the basic way for us to solve the contradictions (or make them compatible)".

To understand the real situations and desirable directions concerning to this Principal Contradiction in the fields of humans, organizations, societies, and the world is a huge task for us to work from now on.

Best wishes always,

Forum: Letters from Readers(Aug. - Sept., 2016)

Naohiko Takayama, Masaaki Shibuya, Takeo Yamamoto, Yorikazu Suwa, and Toru NakagawaTakayama, in response to 'Do We Have Any Methodology of Creative Research in Academia ?', has made mind maps of James Young's book and of Darrell Mann's book and suggests some parallelism between them. Shibuya has pointed out the recent remarkable advance of statistical science using computers and evaluated that such statistical methods are successful in analyzing real data starting with simple models and obtaining fairly complex results, corresponding to the abstraction and concretization processes in the CrePS methodology. Genom analysis, financial engineering, brain science, speech recognition, etc. are such application areas of success, he says. I have been thinking the data analysis with computers in a somewhat separate framework from the problem solving by humans. But I feel we need to consider the data analysis methods with more weights in our CrePS methodology. Yamamoto sent me a comment in late June that we should consider the high risk of Japanese financial catastrophe more seriously in parallel to the poverty problem. He communicated to me again in response to my visual diagram of Professor Hiroshi Yoshikawa's lecture on 'Financial reconstruction and Japanese economy'. Suwa contributed his thoughts on the Low-living Elderly problem, based on his experiences of meeting a number of LLE people in his job as a judicial scrivener. His communication is posted in a separate page [2].

[2] Social Problem:

On the Low-living Elderly Problem: Employee's pension insurance should be applied more widely Yorikazu Suwa (Judicial Scrivener)   The contributor, Mr. Suwa, worked in sales divisions in a big company and after retirement he became a judicial scrivener. Servicing for lawsuits at Summary Court, he met a number of low-living elderly people who are suffering from debt in consumer finance. From such a background, he writes his thoughts in an sample case: A woman who worked for 30 years as a secretary in a foundation is now old in age with no family/relatives and in a hospital. So the foundation is asking its members for raising money for her medical care. She does not have employee's pension, as a matter of fact. In 1975 when she started working at the foundation, Employee's Pension Insurance (which is to be paid half and half by the employee and the employer) in Japan may not be applied to corporations with less-than 5 employees. In 1981 the Employee's Pension Act was changed so that any corporation has to apply the employee's pension to all its employees. But the Act was not enforced strictly and many corporation, including her foundation, did not join the insurance. Missing the chances of joining the insurance, or intent violation by corporation employers, is one of the most significant factors for many elderly people to fall down into low-living situations.

In 1981, a notice was issued by the director of Health Insurance Department of Ministry of Health and Welfare, saying "The part-time employees working for the time length less-than 3/4 of the regular employees are not applicable for the Employee's Pension Insurance". This notice is a big problem because it excluded a huge number of non-regular employees out of the benefits of Employee's Pension.

-- Since I have few chances of facing real situations of poverty in the society, I am not good at thinking and talking on real sample cases. Suwa contributed to explain focal points of real problems on the basis of his experiences. He is another old friend of mine at the YMCA dormitory of the University of Tokyo. I deeply thank him for his valuable contribution.


[3] CrePS Introductory:

Fuda-Yose Tool and Visual Thinking: Part 3: Practices of Using the Fuda-Yose Tool:         Practices by Nakagawa for Visualization Toru Nakagawa

This is the Part 3 of the series of papers jointly written by Akihiro Katahira and Toru Nakagawa.

In this Part 3, Nakagawa describes his practices of using Fuda-Yose method at the phases when the problem has become clearer and some notes/documents are written either by him/herself or by other person(s). The purposes of using the Fuda-Yose tool is to clarify the logics in the documents by making visualized diagrams and to share the understanding with many other people. I explain the basic thoughts of my practices, first, and then describe the concrete process of making visualizing diagrams for the documents typically of the length from half a page (e.g., abstract of a paper) to about 20 pages (e.g., an article/paper, or a chapter of a book). Cases of visualizing practices are chosen from my reports already posted in this "TRIZ Home Page in Japan":

they are

(1) Abstract of Ed Sickafus' paper, and five chapters of Takanori Fujita's "The Low-Living Elderly" book (including;

(2) Introduction,

(3) Cases of falling into the LLE situations,

(4) Higher risks of LLE in near future,

(5) Feelings and thoughts by ordinary people on LLE, and

(6) Author's proposals of LLE policies), and

(7) Lecture note by Prof. Hiroshi Yoshikawa on 'Financial reconstruction and Japanese Economy'. For each example, I explain the process of making the visualizing diagrams, ideas for improving the diagram representation, the finished (rather detailed) diagrams and their simplified versions made on readers' requests, etc.

These examples demonstrate that the visualization with Fuda-Yose Tool is useful for clarifying the logics in documents on complex themes like these social problems. It is required to visualize the logics in much larger documents with different arguments (because all significant social problems and political issues are such cases). Our strategy should be 'Segmentation and Hierarchical structuring'; we need to demonstrate it from now on.

Best wishes,

Toru Nakagawa
