About this site
Toushiki is a dive site on Izu Oshima, the volcanic island in Tokyo Prefecture that lies south of the Izu Peninsula in Sagami Bay. The island's shoreline is largely made up of basalt lava flows from Mount Mihara, and shore dives along this coast are typically entered directly from rocky or lava-formed entry points.
