Kanmurishima Island is an uninhabited island with a circumference of 4km near the exit of Wakasa Bay in Kyoto Prefecture. The site is famous for its natural monument, the Great Horned Plover. The waters around the island are almost entirely surrounded by sheer cliffs, and the underwater terrain is dynamic.

This is one of Japan’s three major clear streams and has a high level of clarity. The water depth is often 3-6 meters, but in some places it can be over 10 meters in depth.

This site is beach entry only. Enter from the gravel beach, and as you descended, the Gorota stones spread out. Once off the coast, it becomes a sandy area, which has several man-made towers of sorts. The water near the entry is shallow but gradually deepens as you go offshore to a depth of over 40 meters.

Tajiri is located at the eastern end of Tottori Prefecture and faces the Sea of Japan. The surrounding coastline has a complex topography and has been registered as a nature park as a “geopark“ on the San-in Coast. The complexity of the terrain continues into the sea, and there are many waterways and horizontal holes, and there are also caves at the half-surface of the water, making it very popular among divers who like the terrain. Compared to other clownfish species, the pink clownfish has a clearer pattern as a juvenile and is redder in color, giving it a clownfish-like design. This is why they are called “Nimodango“ and have become a popular subject.

The Okinose W-Arch is situated on the Etchu-Miyazaki Coast, at the easternmost tip of Toyama Prefecture. Located approximately 1 kilometer offshore, it faces the open ocean.

According to local legend, an ancient shrine once stood in this area, making it known as a power spot. Visiting this site is highly recommended.
