Shizuoka

Shizuoka is a coastal prefecture of central Honshu, Japan, facing the Pacific Ocean. Diving here centers on the Suruga Bay region along the western Izu Peninsula, with access to both shore dives and boat trips. The area features warm temperate waters, clear visibility in good seasons, and a mix of rocky reefs, underwater slopes, and occasional wrecks. Notable dive hubs include Atami, Ito, and Numazu, which provide a range of local dive centers and shore access. Inland attractions like Lake Hinuma add freshwater options within the broader region, but the primary diving focus remains saltwater sites along the coast and offshore islands. Expect diverse marine life including small reef fishes, seasonal pelagics, and macro critters, with conditions that vary by season and proximity to the Tip of Izu and Suruga Bay.
