Dive Spot Guide•
Tanicha Tower
Tanicha Tower is a deep coral tower boat dive off Onna, Okinawa.
Local operator required
Onna-area dive centers are the practical way to reach the site and manage the drop-off.
Plan it as an advanced boat dive for divers who can manage depth, current, and tight buoyancy around a coral root.
About Tanicha Tower
Tanicha Tower is a deep boat dive off Onna Village in Okinawa, centered on a single coral tower rising from sandy bottom. Divers usually work around the root and nearby crevices rather than cruising a wide reef, which keeps buoyancy and line control front and center. It suits experienced divers who want a compact, topography-first site with good odds for larger marine life, and it is best dived on a calm day when current stays manageable.
