Located in Ashizuri-Uwakai National Park, Tatsugushi Bay, home to coral and gorgeous tropical fish, was designated as Japan’s first underwater park in 1970.
The water temperature is high at 16 to 18 degrees Celsius even in winter, and the transparency is stable, attracting many divers from all over Japan throughout the year.
The Ryukushi Coast is a geological museum, with rare rocky landscapes such as Otake-kotake, where rounded joints can be seen in a straight line formed by waves and winds gouging Tertiary-age sandstone, as well as a thousand frogs, Shiborimakura, Ranma-ishi, and Senjyoshiki, all of which are considered to be a geological museum.
Under the sea, there is a colony of shikoro coral, which is said to be the largest in Japan. Visitors can observe the beautiful underwater scenery on a glass boat.
