About Okinoshima Island
Okinoshima Island is a remote Oki Islands boat dive in the Sea of Japan, where volcanic terrain, seagrass beds, wreck and cave options, and a strong fish-watch profile combine into a temperate island outing. It is a guided offshore day rather than a casual shore hop, and the planning reality is simple: use a local island dive base, choose a weather window, and expect a quiet, low-crowd dive scene with plenty of marine life.
