One of Japan's best year-round dive regions — finally in English.
Atami sits at the gateway to the Izu Peninsula, where the warm Kuroshio Current pushes up from the south and fills the coast with life — dragon moray eels tucked into volcanic crevices, drift dives along lava reefs, and sunken wrecks. This is a real dive destination that happens to sit 45 minutes from Tokyo.
