Dive Resort Hahajima

The only dive resort on remote Hahajima Island, Ogasawara. Pristine UNESCO waters with untouched coral reefs and pelagics.

Dive Resort Hahajima is the only dive operation on Hahajima Island, the most remote inhabited island in the Ogasawara (Bonin) archipelago, located approximately 50 kilometers south of Chichijima. This extreme remoteness means divers who make the journey are rewarded with some of the most pristine and untouched underwater environments in all of Japan — waters that see very few visiting divers compared to any other dive destination in the country.

The resort offers boat dives to Hahajima's surrounding waters, where vertical volcanic walls plunge into deep blue ocean, attracting pelagic species including dolphins, sharks, and giant trevally. The coral reefs here are remarkably healthy, undamaged by development or heavy diving traffic. Visibility in the Bonin Blue water routinely exceeds 30-40 meters, creating spectacular conditions for underwater photography and wide-angle diving.

As the sole dive operator on Hahajima, the resort provides an intimate and exclusive experience. On-site accommodation makes logistics simple — guests stay, dive, and relax in a single integrated operation. Reaching Hahajima requires first taking the 24-hour ferry from Tokyo to Chichijima, then a 2-hour inter-island ferry to Hahajima, making this a true expedition-level diving destination for those seeking Japan's most remote underwater frontier.
