Boat drift site for early-summer hammerhead runs.
Boat drift site for early-summer hammerhead runs.
Access is handled through local Shimoda-area boat operators rather than shore entry.
A Point is the Kame-Ne side of Mikomoto Island's hammerhead grounds, where a rocky shoulder drops into open blue water and experienced divers hold position for passing schools. The dive is boat-led, current-sensitive, and organized around short guided drifts, so the planning is as important as the wildlife. It is a pelagic site first, with the terrain and guide discipline doing most of the work.
