About Sanbondake
Sanbondake is an offshore rock reef off Miyakejima, reached by boat and dived as a complete drift when currents and sea state line up. The volcanic island setting and Kuroshio-fed water make it a dynamic, condition-dependent advanced dive rather than a casual shore site, with large schools of fish and occasional sharks drawing experienced divers on the right days.
