Japan

Kozushima Village

Kozushima Village sits on Kozushima Island in the Izu archipelago, within the Tokyo region of Japan. The island is a coastal community with access to the Pacific Ocean’s clear waters, though diving activity on Kozushima itself is limited. With few local dive operators and no large, established dive sites directly on the island, most divers visit for shore access, potential boat trips, or as part of broader Izu diving itineraries. The nearby freshwater option is Lake Hinuma, a far inland feature not associated with saltwater diving. Overall, Kozushima functions more as a gateway point for regional diving in the Izu region rather than a high-volume dive hub.
