1 Gochi Ohanabatake is a protected-area drift dive with rich reef life.
1 Gochi Ohanabatake is the Flower Garden #1 dive in a protected marine area of Shikoku, set up as a boat drift rather than an anchoring site. The workable band is shallow, but the current can run hard enough that sea state matters more than the map. When conditions line up, it is a lively reef dive with branching coral, shoals of fish, and small macro life in the structure.

Scuba Diving
Drift diving is the standard approach; the shallow working band is safest when the current is manageable.
Freediving
Not a freedive site; the boat-based drift setup is better suited to scuba.
Snorkeling
Not suitable for casual snorkeling; the current and boat-based setup make it a scuba site.
