Dogashima Island in Nishi-Izu, Shizuoka, offers complex underwater terrain and rich marine life. Highlights include boat launches from the “Tenmado-do Cave” and “Saku-ne” with undersea hot springs. Suitable for all levels, it showcases the ocean’s changing beauty across the seasons.

Futou is the scenic point of Nishi-Izu. This site can be reach via beach entry or boat entry. There is a small area where you can go night diving all year round. There are caves, caverns, and arches as you progress through the shallow beach sand to the rocky terrain.

There are six boat points in the open sea and four in the bay at Tago. There is also one beach. At the point in the bay, there is a clump of Green Turtle Coral that looks like Okinawa, and much tropical small fish can be seen around it.

This is the most popular cave diving spot in Izu. There are many caves and covern between and around two large rocks called Ushitsukiiwa in front of the harbor.

This dive site boasts dynamic topography, featuring a large offshore root known as the West Root and the Horse Mackerel Root. It’s conveniently located just 5 minutes from the harbor, making it suitable even for those who are not particularly comfortable with boat rides. One of the most spectacular highlights here is the presence of stingrays, especially during early summer. In the peak season, the encounter rate with stingrays can approach 100%, and you may even witness a group of them instead of just one or two. As autumn arrives, the visibility improves, and the already dynamic topography becomes even more fascinating. You can observe kampachi and sunfish circling around, as well as the famous “school of large, motionless snappers“ in the offshore roots. Many divers who frequent this site express their amazement, saying, “I can’t believe I’m in Izu.“

Located in Koganezaki Park, you can enjoy various flowers depending on the season, and entry/exit is very easy to do due to the ramps and handrails. When you enter, you’ll see a wide range of gorotas up to a few meters deep, and beyond that, you’ll see an entire surface of the sand.
