Rural areas need support services to help elderly people sustain their ordinary lives, especially in light of today's aging societies. In Japan, nonprofit organizations and residents' associations, which are based in local relationships, provide support services aimed at helping the elderly with their daily buying behavior. This study provides a comprehensive understanding of the barriers preventing the use of such support services. We collect 133 respondents from semi-structured interviews through door-to-door visits using snowball sampling to show that there are three such barriers: lifestyle, capability, and trust. Furthermore, we discussed measures to reduce these barriers using our results of correlation analysis and analysis of variance. Our findings have implications for a new direction in social marketing for elderly people. As societies continue to age and highly accessible services become ever more necessary, the insights of our study will be applicable not only in Japan but across the world.
