Major Activities

What makes us unique

1) A focus on policy realization

KOSO NIPPON is a Japanese public policy think tank founded in 1997. Our activities are not limited to developing proposals, but also focus on making them a reality. We think about the future of society as a whole, and take a cross-sectional approach to addressing social issues. We work directly with politicians, nonprofit organizations, and the media to get our policies implemented, no matter how many years it may take.

2) Reform from a frontline point of view

Any nation will be better off if the thoughts and feelings of everyday citizens can be reflected in policies and incorporated into politics. With this in mind, KOSO NIPPON goes directly to local governments and their communities, engaging in activities that enable residents to see social affairs as ‘their own business.’

Reform from a frontline point of view

3) Independent, not-for-profit management

KOSO NIPPON is an independent, nonprofit organization. We are funded by membership fees and do not engage in commissioned business. This is why we can speak openly and take action without influence from political parties, politicians, corporations, or anyone else.
