This thesis evaluated the new law since 2015 of the support services by Japanese Juvenile Classification Home (JCH) which is a detention facility for juveniles. The support services by the JCHs is providing psychological and educational individualized support who are facing crime-related or deliquency-related problems based on the requests from any individuals and organizations in community. It is based on the classification for the support services in the former law. This study also examined the role of population density among three categories of large, medium-sized, and small prefectures. The relationship between delinquent rates and support services for the juvenile population three years of before and after the new law among the three geographic categories was examined. Delinquent outcome rates significantly decreased among the geographic categories. By contrast, support services by the JCH rates significantly increased among all three geographic categories. Small and medium-sized had more the classification for support services and support services than large prefectures; their support services rate were higher than delinquent rates. With regard to common services, workshop (providing lecture or workshop to the group of people) was most major, institutional counseling (providing individualized services based on the request of organizations) was second, case conference (attending case conference of other organizations), and individual counseling(providing individualized services based on the request or individuals) was third. Most of these four types of services were provided more in small and medium-sized prefectures than large prefectures. The results supported the richness in social capital in small and medium-sized prefectures. Though this study did not examine the effects of support services by the JCH, but it suggested the needs in the community has been increased. Considering the basic characteristics of the support services, it could meet the Risk-Needs-Responsivity principle, but further information about the clients’ basic demographic, risk level, criminological needs and their responsivity is needed in the future.
