Ce que cela donne

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.

Sites phares

Commencer ici

Yaene
West-side harbor access via slope or steps and a large outer arch.

Guide de planification

Checklist opérateur

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.
