The interactions of the aged were considered to be essential for aging in place. This research was based on surveys of the aged living in a depopulated region where the changes were more drastic. 1. Families, relatives, friends and neighbors had different functions to support the aged. Welfare services not only supported their living but also lessened their loneliness. 2. In winter, interactions tended to decrease because of heavy snowfall, but in some cases they increased because the aged had more free time, or their families visited more frequently to support them for shopping, snow shoveling and so on. 3. According to aging, interactions tended to decrease.
