SIIF Social Innovation and Investment Foundation

Japan Social Innovation and Investment Foundation ( Social Innovation and Investment Foundation )

By leveraging our unique perspective as a foundation, we can create an action aiming to help build the base for a society in which the resolution of social problems and the creation of value take place autonomously and sustainably.
Working with companies, local governments, NPOs, and educational institutions, research and other organizations, we propose and execute numerous plans and provide assistance aimed at realizing an ecosystem for social and economic resources that transcends the conventional frameworks of self-help, public help and mutual help.
