Tatsukushi Diving Center

Kashiwa Island in Kochi is a macro paradise with shallow, clear waters perfect for spotting nudibranchs, crustaceans, and gobies. Famous for rare species sightings, it attracts both beginners and seasoned divers. Calm conditions make boat access the preferred choice for exploring this rich underwater world.

Uguru Island is the southernmost town in Shikoku, 23 kilometers off the coast of the city of Shukumo. Due to the Kuroshio Current, the visibility in this area is one of the highest in Japan, and on a good day, the visibility can be as high as 50 meters. With its dynamic terrain and coral habitat, you can see tropical fish all year round. There are both big fish spots and macro observation spots, and both beginners and experts can enjoy them.

Nishiumi is located at the southwestern tip of Ehime Prefecture, on the border with Kochi Prefecture, and around the West Sea Peninsula, southwest of Aina Town. Boat diving is the main activity, but beach dives are also available.

This dive site is just a two-minute boat ride from the West Sea, and it can also be reached by swimming in approximately 25 minutes. For those feeling adventurous, swimming to this site is an option, especially during the cooler months when catsharks are plentiful, and jawfish habitats are spread across the area. Typically, it serves as the first dive site due to its deeper average depth. It’s also well-suited for deep diving training, allowing divers to quickly descend to depths of up to 40 meters. Additionally, it’s an excellent choice for those interested in participating in a training course.

This is a point where more than 20 square iron boxes of 3m in length and width are sunk. The former Nishinoumi Town sunk many of these boxes a long time ago in order to provide a home for fish. The place is crowded with migratory fish and the boxes are falling down on the sandy bottom. You can often take the route of going around and coming back to see the fish, but if you like macro, you can stay here and find pikachu and other nudibranchs.

This dive site is characterized by clusters of both soft and hard corals at a depth of approximately 20 meters. Frogfish seek refuge within the crevices, and at times, schools of migratory fish make their way through. While a diverse range of fish gather in this area, the presence of strong currents often requires careful consideration of diving conditions. Although typhoons had previously caused significant damage to the hard corals, there are indications of recovery as of 2023, making this site all the more appealing to divers.
