Abstract
The advocates for the cooperative housing in Japan generally appreciate the free choice of design on physical side and the higher interaction with neighbors on mental side. In my opinion, the collective housing is a political body which promotes the participation, the core of democracy and may lead to setting up the better governance. The condominium, the dominant type of collective housing in Japan, has generally suffered from the lack of participation by residential members while the cooperative housing strengthens community relationship and further assists the setup of ideal governance. In political science, the restoration of community is attracting attention, which has shown as the communitarianism, the thesis of criticizing the excessive individualism and also as the social capitalism recently flourished. On this study I wish to demonstrate, through various research and analytical works, how the community will restore on political side and how it will serve to build the governance with mutual trust and participation.
