Abstract This study focuses on network building among stakeholders to promote collaboration. The study also uses a case study of a depopulated municipality to identify the important factors to consider when establishing comprehensive support systems. From December 2022 to December 2023, the author conducted interview surveys with a local government administrative officer, four Social Welfare Council staff members, and one think tank employee in Town A. Before implementing the Layered Support Development Project, Town A had previously instituted the “local mutual support model,” which involved conducting volunteer monitoring activities and utilizing general consultation hubs. The sense of security and trust generated by these monitoring activities is exemplified by the following statement made by a volunteer: “Because we go to check on them regularly, they even tell me their specific illness or date of hospitalization, as if we are actual family members.” This mutual support network and friendly resident monitoring form a community safety net. The local government and Social Welfare Council staff recognized the importance of ensuring early detection, responding to residents’ need for precautionary support, and acknowledging the crucial role of volunteers. Consideration could be given to incorporating actionable strategies to enhance the self-efficacy of volunteers and foster a shared understanding among staff to build a comprehensive support system for depopulated municipalities.
