Okinawa Prefecture

Okinawa Prefecture is a maritime region in southern Japan, famed for its tropical-leaning reefs, clear waters, and abundant marine life. The area comprises the main Okinawa Island and the Yaeyama chain, including Ishigaki and Iriomote, with diverse diving that ranges from drift dives along coral walls to calm shallows near drop-offs. Typical conditions feature warm water year-round, good visibility in many sites, and a variety of hard corals, reef fish, and occasional larger pelagics. Access is convenient via Naha and regional ports, making both shore and boat dives feasible for recreational divers.
