Our initiatives

Japanese society faces a myriad of challenges as it grays at an unprecedented pace—a situation aggravated by the nation's low birthrate.

Many of Japan's regional communities are edging toward "extinction" due to rapid depopulation. Furthermore, Japan—the world's fifth-largest greenhouse gas emitter—is confronted by daunting tasks in its fight against global warming.

Experiencing these problems ahead of most other nations, however, will provide Japan with a prime opportunity to revitalize itself and spur much-needed growth. If it can overcome these challenges, we believe Japan will be blessed with new demand for its technologies and services that will propel new economic activities.

Solving these pressing issues will require a change of mind-set. We should nurture the notion that surmounting challenges such as global warming and an aging society—with the power of local communities working to improve the lives of their residents—will give rise to new demand and industries, boosting economic activity further. This mind-set holds the key to establishing a sustainable society.

This belief inspired us to create the Platinum Society Network in August 2010. The network aims to facilitate regional movements and orchestrate efforts to create eco-friendly, comfortable communities across Japan.

What is a Platinum Society?

Developing nations generally regard advanced nations as a model they should emulate. Developed nations, on the other hand, must carve out their own future path. Japan no longer needs an overseas model on which to base its advancement and, therefore, must decide what kind of society it should create for its people.

We have developed a concept of the society we think Japan should aspire to establish. We call it a "Platinum Society." This is a dignified society that cares deeply for the environment; can comfortably secure resources it needs; can be participated in by men and women, young and old; provides spiritual fulfillment and material wealth; and offers fair employment opportunities. Through frequent discussions, our vision of a Platinum Society will keep evolving, as each community develops its own characteristics shaped by its historical background and geopolitical conditions.

It is impossible to foresee what will happen in the future. But one certainty is that we must take action to make a Platinum Society a reality.

Platinum Concept

Our "Platinum Concept" is an idea in which people collaborate toward the creation a Platinum Society. To make this concept a reality, the network must have structured goals and activities; share structured knowledge; and create a network of people who share this knowledge and are determined to move the network forward. The Platinum Society Network orchestrates these essential activities.

Platinum Society Network

Platinum Society Network is a nationwide organization aimed at creating what we call the Platinum Society, a dignified society that is as admired and treasured as platinum. Such a society cares deeply for the environment; is able to comfortably secure resources it needs; can be participated in by men and women, young and old; provides spiritual fulfillment and material wealth; and offers fair employment opportunities. The network proposes policy solutions to the political and industrial sectors as well as to citizens so they will be encouraged to act. Establishing a more sophisticated, comfortable society by bringing Japanese intelligence and wisdom together is another mission of the network.

The organization will create economies of scale and new values in such fields as knowledge/information, manufacturing/craftsmanship and distribution by forming a network of municipal governments, universities, research institutions, private enterprises and cities overseas. Each of these entities has thus far carried out projects like this singlehandedly.


Platinum Vision Award

The Platinum Network Society presents awards to entities that have solved regional challenges through the creation of a new industry or other ingenious measures. We believe sharing their endeavors with a wider audience will help us create a Platinum Society. We also certify any local government that wins this award as a Platinum City.

Several working groups conduct investigations, discussions and research in specific fields to produce innovations.

Platinum Society Handbook

The handbook describes advanced cases working toward the creation of a Platinum Society and systematically analyzes factors that led to their success so other local governments can apply these methods to their own cases.
