The point, situated on the north side of Mikomoto Island, experiences the influence of both low and high tides. Notably, the three roots exhibit symmetry, with the west side being flat and gradually deep, while the east side features clustered roots.

Situated offshore Enokuchi and Mitsu-ne on Kamikomoto Island, this site is highly affected by tides. The depth of the reef ranges from 22 to 25 meters, peaking at 19 meters towards the end before descending sharply to 45 meters. Due to significant tidal influence, it’s considered a challenging dive, particularly for beginners.

This is the “standard“ dive site on Mikomoto Island. There is a large root called “Kadone“ in the west direction, and the basic diving style is to wait for the root and then surface on the spot. Average depth: around 20m

This dive site, situated at the southernmost tip of Mikomoto Island, is renowned as the prime location for encountering hammerhead sharks and white-tip reef sharks. It stands out as the foremost spot for such encounters.

During early summer, hammerhead sharks gather in large schools at this location, circling repeatedly in a captivating manner. Divers can enjoy extended observation periods as the sharks navigate around roots or rest on rocks.

There are a number of diving spots around Kamikimoto Island, an uninhabited island off the coast of Shimoda. It is a 20-minute boat ride from the harbor to the dive site. It is a popular spot for hammerhead sharks to appear from summer to autumn when the Kuroshio Current approaches the Izu Peninsula.

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.

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 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.“
