When viewed from East Izu, Oshima Island is the mysterious gem floating on the horizon off in the distance to the right of Hatsushima. This pristine diving Mecca can be reached by ferry from Tokyo in less than 2 hours, and from Atami in 60 minutes.
Being farther out in the ocean, the water surrounding Oshima features superior visibility and a number of pristine shore-entry dive sites that offer excellent variety to all levels divers. Mild currents at some sites allow divers the feel of a short drift dive.
The fish and other marine life on Oshima are generally encountered in greater numbers and in larger sizes, compared to many mainland Izu dive locations. It’s a fantastic site and a rather well-kept secret, relative to other Izu sites. The easy access from Tokyo makes it an ideal getaway.
Oshima Island hosts a number of quaint minshuku and local shopping that make a weekend stay quite enjoyable.
