Abstract
In 2011 and 2012, the project for the 'new public' by the Japanese government has advanced in every Japanese prefecture. Nagano Prefecture has established a committee, 'Shinshu Round Table for Citizen Cooperation', which includes NPO representatives, representatives from industry and labor organizations, scholars, and administrators. They developed the project called Support and Promotion of the New Public in Nagano. The New Public would be realized by cooperation between various private sector associations and the public administration. The expansion of cooperation to enhance the rich public space in Nagano is the most important outcome of the two-year project. Here the project for cooperation in Nagano is introduced, and the background and basic concept of this project are explained.
