Despite dramatic advancements in science and technology, today's society faces many issues including declining birth rate, aging of population, growing fiscal deficit, increase in environmental burden, depopulation in rural areas, and increased risk of natural disasters. These issues are all related to sustainability and common throughout the globe, with some differences per country, as indicated by the adoption of the SDGs (Sustainable Development Goals) at the United Nations Sustainable Development Summit in 2015.

While various efforts have been made to tackle these issues, it is clear that a segmented approach treating them separately has limited impact. Instead, we should take a holistic approach towards the real problems in respective regions, taking into account the varied local resources available.

We believe that intergenerational co-creation is an important methodology in this regard. This is because an intergenerational approach makes people active, affects their mindset, enables gathering of diverse knowledge, facilitates consensus formation, and enhances sustainability of activities.

This is not to say all problems can be solved by this methodology, or that there is no room for improvement. Hence, we would like to further develop methods of intergenerational co-creation as a social technology, so that people in many regions can take advantage of it. This will, we believe, help lead to the realization of sustainable society.


Our aim can be summarized in the following three points:
(1)We will clarify how intergenerational co-creation is effective in achieving sustainability in cities and regions.
(2)In the areas where intergenerational co-creation is expected to be effective, we propose mechanisms to promote, put into practice and improve it.
(3)We will make efforts to implement these mechanisms in our society while building a network for exchanging experiences and know-how.

Almost all the projects in this research area have regional fields, owing to the above point of view, providing a venue for first verifying their research hypotheses. In addition, each aims for activities to continue in some way so that they become ingrained into society beyond the RISTEX research period.

By "co-creation," we mean a cooperative activity to create something together, rather than simply allowing one generation to take care of the other. What we expect to be created are not necessarily physical products, but could well include values such as improvement in health or well-being, and reduction in fiscal deficit or environmental burden.

Message from the Area Director

It has been a while since people recognized the importance of "sustainable society." Since then, there have been advances in various science and technology, accumulation of capitals, and establishment and maintenance of systems. However, unfortunately we cannot say that the sustainability of our society was enhanced. There are many global environment issues which continue to deteriorate. Cumulative deficit in Japan is growing rapidly, close to exceeding the economic growth rate. There is a concern of the future of many local governments due to depopulation. The gap between the rich and the poor has been widening in many advanced countries.

It is known that after a certain level of income is attained, the level of happiness and life satisfaction do not improve substantially with income increase. Although Japan seems to have entered that stage, we cannot ignore that the level of life anxiety in Japanese people shows an increasing trend. More often than before people say that "the world is becoming degenerated" or "it is becoming more difficult to live." These vague senses of anxiety seem to be deeply related to the issue of sustainability.

There are various approaches to build a sustainable society. I would like to pay respect to many people who are making efforts on respective themes in their own ways. In this area, we focus on an attempt to build a sustainable society with the method of "intergenerational co-creation." Sustainability does not mean to keep on repeating the same thing; it is necessary to closely examine what should be changed and what should be maintained. In the world with uncertainty, consensus needs to be formed in the society, including a viewpoint of what should be passed onto the future generation.

In old days, production and living space used to be integrated, and people from different generations cooperated at home and communities in various ways. In such society, people realized they are in charge of a slice of eternal history called "now". Such opportunities decreased with the advent of mass production, nuclear family, urbanization, and globalization; meanwhile, recent progress in information and communication technology enabled people to bond and help with one another in new ways.

We will keep on to strive toward building a new way of lifewhich can make people feel secure that the prosperity of humankind will continue and also toward necessary science and technology for society to realize it
