Ainan-cho Nishiumi Pleasure Boat (Uwakai Kaiiki Koen Marine Park)

The Uwakai Kaiiki Koen Marine Park is a paradise of tropical fish and coral reefs. Here the water temperature is never below 15 degrees, even in winter. The underwater pleasure boats, “Yumekaina” and “Gaiyana” take you to this scuba diving mecca. As the central viewing room of the boats dive down to 1.1m, you can enjoy the fantastic underwater scenery of the coral-covered sea floor and schools of tropical fish swimming by from the convenience of the boat. Better still, experience the warm water of the Uwa Sea and check out the little-known creations of nature thanks to the incredibly clear ocean water.
