Boat-access big-fish drift site off north Iriomote
Iriomote Tokakinsone is a boat-access drift site off north Iriomote, built around a complex rocky root that rises through the reef. It is known for strong water movement and big-fish encounters, so the dive plan centers on timing the drift, staying close to the structure, and keeping a sharp lookout for pelagic action. The result is a high-energy reef dive rather than a slow sightseeing stop.
Site Conditions
Safety Notes
Beginners can join with experienced guides, but strong currents require caution and close briefings.
Access Restrictions
Boat access only; best handled with operators comfortable running current-driven dives.
Community notes to help plan your visit.
Scuba Diving
Drift-style dive over a 15 m mountainous root, with big-fish action and schooling pelagics around the structure.
Freediving
Less suitable for casual freediving because the strong currents are a defining feature.
Snorkeling
Not a casual snorkel site; the drift and current make it better for boat divers than for surface-only visits.
