The purpose of this research is to investigate how social enterprises have the community participates in their decision-making and implementation processes. As a result of the case study focusing on two Japanese social enterprises, they took not a formal method like asking local residents to become board members but an informal method like creating opportunities that all local residents can unburden and share worries about their daily lives and giving power for implementing projects to local residents so that they can practice ideas to solve the worries in order to dig out demands of the community and satisfy them accurately.
Distinguishing their impacts at individual, community and organization levels, I also show that such informal methods bring necessaries for creating stable and sustainable inclusive society.
