Diving in Ugusu is located within a national park called Koganezaki Beach Park. This park is situated on the west coast of Izu about an hour north of Kumomi. It can be reached from Atami in about 1 1/2 hours.
This easy entry/exit shore dive site is in the beautiful national park called Koganezaki Park. You'll see a rocky wall that drops off to a white sandy bottom. A variety of sea life abounds in both of these areas. The max depth is about 20 meters, and there is almost never current, so this site is ideal for all levels of divers.
Night diving is available every Saturday nights from May 15 until September 15, and then you can see all the other creatures that come out at night. Nitrox is available by reservation.
The facilities of Ugusu are quite nice. The grass-covered site is deal for picnicking and is perched on a protected bay, which is surrounded by cliffs and wooded areas. There are plenty of showers and a hot tub to relax in after dives. For overnight accommodation, there are dorm-style rooms, as well as spacious log cabins for larger groups.
There is also excellent boat diving, that is very reminiscent of Atami in it's abundance of soft corals.
