How do you get to Dobuiso?

You first reach Chichijima by ferry from Tokyo, then head out by boat to Dobuiso as part of the island diving circuit.

Is Dobuiso good for beginner divers?

No. The site is considered advanced because strong current is common and the dive is usually run as a drift dive.

What current should I expect at Dobuiso?

Strong current is common, so the dive plan should be simple and you should stay close to the guide and the group.

What gear or planning should I bring to Dobuiso?

Treat it as an advanced drift dive: keep the plan simple, listen closely to the guide, and be ready for action during the safety stop too.

What is Dobuiso like to dive?

Dobuiso is a steep, current-driven Chichijima dive with a big-fish profile and a lot of action in open water rather than on a flat reef.

What visibility should I expect at Dobuiso?

The Ogasawara sea is often described as clear, but Dobuiso is current-sensitive, so visibility changes with season and sea state.

What wildlife can I expect at Dobuiso?

Dogtooth tuna, jacks, barracuda, reef sharks, manta rays, and dolphins are all realistic possibilities around the site.

When is Dobuiso usually best?

About Dobuiso

Dobuiso is one of Chichijima's top big-fish dives, with a massive underwater pillar and steep rocky slopes that turn the site into a current-driven channel dive. The appeal is the mix of dogtooth tuna, jacks, barracuda, reef sharks, manta rays, and dolphins that can show up in the blue as well as on the safety stop. It is an advanced boat dive that rewards patience, drift discipline, and the right weather window.
