Abstract
This research examines the realization of integrated community care systems addressing increasing medical and nursing care needs in an aging population. It aims to verify the effectiveness of international P2M theory (Profiling Management and Platform Management) in designing day care services for the elderly. The study focuses on the Seiran-kai Group in Yamaguchi City, which improved its elderly day care service system to a wellness community model. Through this case analysis, we seek practical insights for constructing core services in regional integrated community care systems. The research is expected to verify P2M theory's practical applicability and contribute to new methodologies for designing and improving elderly care service systems.
