The Izu and Ogasawara Islands, formed by an erupting submarine mountain range, offer a distinctive diving adventure that captivates both novice and seasoned divers. Easily accessible from mainland Japan, the Izu Islands provide daily boat, plane, and helicopter departures, while the more secluded Ogasawara Islands await those willing to embark on a day-long ferry journey. The effort to reach these remote waters is rewarded with encounters among coral reefs teeming with life and WWII wrecks that tell stories of the past.
Divers in these regions are treated to the sight of unique species endemic to the islands, alongside the thrilling opportunity to swim with thresher and hammerhead sharks. Sea turtles glide gracefully through the waters, and in certain locations like Ogasawara and Mikurajima, you might even find yourself surrounded by pods of up to 200 wild dolphins. Whether you're exploring the vibrant shallows on a shore dive or venturing into the depths from a liveaboard, the Izu and Ogasawara Islands promise an unforgettable marine experience.
The Izu Islands and Ogasawara offer some of Japan's most captivating dive sites. Among the highlights, Mikomoto Island in the Izu chain is renowned for its thrilling drift dives, where divers can encounter hammerhead sharks. The "Submarine Wreck" at Hachijojima is a notable wreck dive, offering a fascinating glimpse into underwater history. For those preferring shore dives, Niijima's Honson Beach provides easy access to vibrant reefs teeming with marine life. Unique experiences include night dives at Ogasawara, where the bioluminescent plankton creates a sparkling underwater spectacle. Both regions cater to a range of divers, balancing shore dives with liveaboard options for extended exploration of remote sites.
The Izu Islands and Ogasawara offer year-round diving opportunities, attracting divers with their rich marine life and diverse underwater landscapes. Water temperatures range from 17°C–27°C/63°F–81°F, with cooler conditions in winter and warmer waters during summer. Visibility typically spans 10–30 meters/33–98 feet, influenced by currents and plankton blooms.
While diving is feasible throughout the year, spring and autumn are particularly favorable due to milder weather and optimal water clarity. Summer may bring stronger winds and currents, while winter sees cooler temperatures. Divers should consider these seasonal factors when planning their trips to ensure an enjoyable experience.
