Sanbondake

Sanbondake is about an hour’s boat ride from Miyakejima and is officially called Onohara Island. It is an uninhabited reef floating off the coast of Miyakejima. This site is for advanced divers only due to the strong current. This dive is a complete drift style dive. It is only possible to dive when sea conditions and currents are right. It is the most dynamic point in Miyakejima, where large schools of fish and large migratory fish can be seen.

You'll see huge schools of sea squirts and hawks, and you're also likely to encounter migratory fish such as the giant campachi. Swallows are also often seen. There are also a lot of hammerhead sharks. Occasionally, you'll encounter a tiger shark.
