We report The "Sharing and Self-Caring" gym on Tarama Island, Okinawa. There are a large number of patients with metabolic syndrome on the island, which is a community health concern. To encourage people in the community to engage in physical exercise and prevent them from developing metabolic syndrome, we established a gym where they shared fitness equipment that they had bought but not used in a while. During the course of establishment, we employed a community-oriented primary care strategy.
