What It Feels Like

Regulus Diving, Hisaichi Divers Club, Sea Dive and Arabesque are among the locally listed providers offering access to island waters. Yaene and Sokodo/Sanmata present relatively approachable guided shore routes, while exposed Nazumado can deliver strong current, dense fish life and sometimes pelagic visitors. Local boat sites include Idesari arches, Tarudo, Kyokuchobama and an exterior-only shipwreck. Volcanic geography and Kuroshio changes mean no site is always open.

Signature Sites

Start Here

Yaene
West-side harbor access via slope or steps and a large outer arch.
Sokodo / Sanmata
East-side beach/jetty route with shallow sections, an arch and fish life.
Nazumado
Open-ocean, current-sensitive shore dive known for fish concentrations and occasional larger animals.

Level Up

Idesari
Boat-reached irregular arch and reef contour with possible changing current; local guides can vary depths to match the group.
Kyokuchobama
Reef and wall profile reported to drop to around 30 m, with seasonal small marine life and intermittent pelagic visitors.
Tarudo
Near-port east-side boat route with sand and a short wall; still a sea-dependent, guide-selected site.

Advanced

Otchogahama
South-coast drop-off and cavern-like volcanic structure.
Shushoke / Kyukeijo-shita
Irregular lava entry, arches and channels.
Sunken Wreck (Chinsen)
Boat-only exterior wreck observation in a current-prone area.

Planning Playbook

Operator Checklist

Book with an island-based operator and give recent dive history, certification level, medical conditions, equipment needs and flight/ferry timing. Operators may swap between Yaene, Sokodo, Nazumado and boat sites on the day. Confirm rental weights, cylinder type, nitrox analysis, port permissions, designated diver entry areas and where surface signaling is required. For multiple dives before a Haneda flight, arrange at least the applicable DAN surface interval and preferably additional margin. Occasional nearby Hachijo-Kojima boat trips may require far more experience than routine local boat dives.
