Domestic elderly population is rapidly increasing and the elderly support issue rises as a social problem due to the aging and the trend toward the nuclear family. The policy of state, however, falls short of the reality. This elderly support issue is a task to deal not only with an elderly alone, but together with family and society. Now the retirement home is increasing by the involvement of the state, but with much difficulties in terms of finance, manpower and the quality of service. Especially the role of Buddhist social welfare, as a realm of religious social welfare in private welfare sector, is more increasing. Buddhism provides the elderly with psychological rest, helps them prepare the death comfortably, and enables them to recover the self-esteem through spiritual wel-being. Concerning Buddhists, Buddhistic principle should be educated and religious life be practiced. Not only the elderly but facilities workers and families should take part in Buddhist lecture meeting for smooth family relations. Facilities should be opened to community people so that they could contribute to the social unification. The purpose of this study was to present a plan to activate the religious life based on the survey of the degree of religious life and the sympathy to social welfare thoughts focusing on retirement home, the medical welfare facility for the elderly, that is, Buddhist-operating retirement home.
