Located in the western part of Ehime Prefecture, Akihama is a beautifully scenic sea with a rias-style coast and a fine white sandy beach of about 300m in length. You can enjoy a wide range of life forms, from macro to migratory and rooted large fish.

The only sunken battleship of the Japanese Navy that can be seen in Japan, sinking on Katsura Island in Yamaguchi Prefecture in the Seto Inland Sea. It is 224 meters long and 34 meters wide and sits at a depth of 40 meters to 10 meters.

At Coral Beach on the uninhabited island of "Deer Island," National Park Special Protection Area No. 7, the water suddenly deepens from shallow to deep at a 45-degree angle. A rich ecosystem has been built here, with coral and shallow bays scattered about that serve as shelter for small fish, and deeper areas in the immediate vicinity. In summer, schools of yellow croaker appear in this area at a high rate, and kampachi, horse mackerel, squid, and other fish congregate to prey on them.

National Park Special Protection Area, site 5, Black Fly. Because the currents are often fast, we often choose this point on days when the tide is not moving and the sea conditions are favorable. This is a special point with an overwhelmingly large number of fish, and across the rocks to the north is a hard coral colony and to the south is a large colony of soft corals and nannyo goatfish. This is a place where you can enjoy the condensed scenery of the ocean in this area at a single point.

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 the first site in the National Park Marine Protected Area, the “Flower Garden site #1“. It is a special dive site that is difficult to anchor and can be dived by drift diving; it is easy to dive safely in the shallow range of 5m-12m, but the current is often too fast, so choose the sea conditions and go there when it is not a problem.
