Abstract
This research clarifies how to promote community partnerships to prevent social isolation of elderly people, and the change in resident attitudes caused by the measures in an apartment complex in Yokohama. We focused Kachida area where community groups address social isolation issues, making a partnership among local groups including local government. We investigated the process of making partnership and starting activities, the organization and the roles of community groups, and the contents of the activities. In addition, we research the change in attitudes of residents by questionnaire investigation. As a result, a community group and some social welfare members have big roles and burdens of community partnership to prevent solitary death. The people who have longer residence years and who are older feel sense of ease, however the people who have shorter residence years and who are younger feel sense of fear. We require multigeneration interchange to prevent social isolation and isolation death.
