Abolition of discrimination and subsumption, both of which are common problems beyond the regions in recent years, are attracting global attention especially from among the Japanese mental health and welfare policies and are on the move to break the current status of the hospital centralism generating a considerable sense of crisis. Under this circumstance, the aim of this study is to clarify the overall structure of the mental health and welfare system under a new cohesive society. The first focus is the comparative verification regarding the determination of elements of the next-generation society system via the classification of the policies involved in the development of local communities. The second one is the re-examination of the difficulties about securing quality of life in a local community as well as building the structure of a new scheme (case analysis of community care; international comparison of concepts and approaches of the citizenship). The last one is the development of a community program to build the framework of the "community care". With these being the main focuses, this study aims to conduct a theoretical and experimental study in order to present the framework of a polyphyletic recycling society to be achieved in a systematic and comprehensive manner from the interdisciplinary perspective of social welfare, medical care, justice, and policies.
