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.

Depth range, seasonality, and planning context.

Shallow coral communities are documented at 1-5 m around Iki, with an offshore diving spot near Nishikihama around 10 m; the broader destination also includes current-swept boat points whose deeper sections are not consistently published.
Best Season
Fall for the biggest fish schools; winter can bring jellyfish and cooler water.
Typical Conditions
Coral and seaweed habitats sit in a current-fed Genkai Sea setting, with boat drift sites and some calmer beach entries elsewhere on the island.
Safety & Access At Iki Island
Site conditions, restrictions, and access requirements.
Site Conditions
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.

Community notes to help plan your visit.
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.
