Minamitsuru District

Minamitsuru District is a mountain-adjacent administrative region in Yamanashi Prefecture, Japan. The district itself is inland and not a traditional dive destination, but nearby freshwater and coastal access within easy reach of Tokyo contribute to regional outdoor activity. Inland lakes in the area provide opportunities for freshwater diving exploration when conditions permit, and the broader prefecture offers access to as well as proximity to the Pacific coast for saltwater options. Development of scuba activities in this district is limited; divers typically base themselves in nearby urban centers and travel to freshwater sites like Lake Hinuma for shallow, temperate dives and to coastal areas further afield for ocean diving along the North Pacific. Expect cool to temperate water, moderate visibilities, and common freshwater species rather than iconic tropical reefs. This region’s diving character is practical and limited in scope, best suited for local divers or travelers planning a coastal side trip from central Japan.
