The best diving near Tokyo and surrounding areas (Kanagawa, Saitama) is on the Izu Penninsula, about 100 kilometers away from Tokyo. The most popular dive site with easy access is Atami, a 45 minute bullet train ride from Tokyo station. On the west side of Izu, Osezaki has dependable conditions even with approaching typhoons. Furthest south on the peninsula, Mikomoto offers diving for qualified advanced expert divers. In Izu, we visit a variety dive sites for every skill level.

Diving in Japan

There is a diversity of scuba diving around the country. In the south, Okinawa and the Ryukyus are best known for their tropical waters, diverse coral and marine life, and beach resort atmosphere. On the Sea of Japan, dive destinations such as Sado Island can supply the diver with a close up view of sheephead and other fish that are not common in other parts of the world. Up north in Hokkaido during winter, ice diving provides a glimpse into a completely different environment.

Diving around the World MORE >

We also have dive tours to destinations around the world. For example, just a few hour plane ride away from Japan, in Micronesia, Guam, Saipan, and Rota offer some of the best diving in the world.
