Nakanoshima Hole is a dramatic hole dive with strong current sensitivity.
Nakanoshima Hole is a dramatic hole-topography dive in Nakanoshima Bay with a shallow entrance, a vertical drop, and bright light-silver contrasts through the shaft. It is a good fit for guided dives that want shape, color, and schools of small fish rather than long cruising. Conditions can turn serious on the open-ocean side, so timing and current awareness matter.

Community notes to help plan your visit.
Scuba Diving
Best as a guided topography dive for certified divers; the shaft and schools of fish reward controlled buoyancy.
Freediving
Not a freedive-first site; the depth and current make it better suited to guided scuba.
Snorkeling
The operator lists snorkeling, but the site is mostly about the hole and its topography rather than a long snorkel circuit.
