Boat dive area with arches, tunnels, and soft coral near Atami.
Boat access and site selection are typically arranged through a local dive center.
Boat-access dive area in Atami's Izusan district. Local operators run it as a guided boat dive with shallow rock structure, arches, tunnels, and soft coral that can suit both scenic wide-angle and closer macro work. The site is shaped by tidal movement rather than shore entry, so route choice, timing, and dive plan matter more than a simple swim-in. Expect clear water on good days, changing flow, and a day-trip style schedule.
