About Budaine
Budaine is one of several dive sites around an uninhabited island off the coast of Shimoda, reached by boat from the harbor. It is known for pelagic encounters when the Kuroshio Current moves in. From summer to autumn, large schools of hammerhead sharks are commonly seen, with chances of other sharks and big open-ocean visitors carried in by the current.
