Boat-run Kerama drift with strong current, clear-water visibility, and a famous manta-cleaning-station feel.
About Uchizan
Uchizan is a high-energy Kerama drift dive where open-ocean currents sweep over a deep reef and a famous manta-cleaning-station area. It is best treated as a boat-run advanced dive with good gas discipline, fast descents, and a plan that assumes the water will keep moving. Expect manta rays, giant trevallies, sea turtles, and other large-schooling fish when the site is on.
