In order to establish “community-based integrated care systems”, housing for those who find it difficult to remain in their homes should be provided. This study focused on Life Support House (LSH). Based on results, the role of LSH for residents to live continuously in their communities can be properly assessed. Questionnaire surveys of LSH and municipalities and interview survey on 12 LHS were conducted. Responses were analyzed by population scale. In smaller population areas, LHS cover shortage of welfare facilities and senior housing. In larger population areas, LHS provide residences to people in low-income.
