Genkai Sea island dive destination with coral-rich shallows, seaweed beds, and current-driven boat points that attract dense fish schools.
About Iki Island
Iki Island is a Genkai Sea diving destination between Kyushu and Tsushima, where coral-covered shallows, seaweed beds, and current-fed fish life sit alongside offshore points with giant block-like rock formations. Many dives run as drifts or short boat hops, so the island suits guided planning more than casual drop-in diving, while calmer beach sites provide easier options on some days.

Safety & Access At Iki Island
Hazards, restrictions, and access requirements.
Key Hazards
Strong current
Safety Notes
Currents can carry plankton and may be strong; plan dives for conditions and maintain good control and buddy awareness.
Access Restrictions
Boat access is the practical default for the offshore points, and drift-style routing with no anchoring is common.
Legal Notes
Iki-Tsushima Quasi-National Park and marine park zones cover parts of the island, so site-specific rules and local-guide instructions matter.

Scuba Diving
Scuba is the main fit for the offshore boat points and the current-driven megalith-style formations.
Freediving
Freediving is best limited to the calmer shallow reef and beach sites; the offshore current points are better left to scuba.
Snorkeling
Snorkeling works on calm beach sites, but the current-driven offshore points are better for guided boat dives.
