Introduction Medicine, particularly family medicine, is crucial to community health and well-being. Its impact on sustainable community care is significant, especially in rural settings with unique dynamics. Recent trends highlight the need for collaboration between family physicians and community members to foster effective help-seeking behaviors (HSBs) linked to improved quality of life and self-efficacy in self-management. This study explores rural communities' perceptions of community care and the integration of family physicians into rural healthcare, enhancing its sustainability. Method A thematic analysis based on relativist ontology and constructivist epistemology was employed. The study was conducted in Unnan City, Japan, involving 81 rural community members. Focus group interviews were the primary data collection method. The research team, comprising a family physician, a non-profit organization director, and a medical educator, analyzed the data, ensuring a balanced and unbiased approach. Results Four key themes emerged, such as understanding the burden felt by existing organizations, continuously engaging in meaningful community activities, steady activities matched to the community's pace, and viewing all places as opportunities for exchange and learning. These themes reflect the need for better information sharing, respecting community dynamics, and incorporating family physicians into various community interactions for effective healthcare delivery. Conclusion This study emphasizes the critical role of family physicians in rural healthcare. It identifies the need for meaningful engagement with local communities, adapting healthcare to the rural context, and using various community spaces for health education. The findings advocate for a community-centric healthcare approach, which respects the unique dynamics of rural areas, fostering a sustainable and responsive healthcare system. Future research should include diverse rural settings and quantitative methods for broader applicability and deeper insights.
