Located in the Genkai Sea, this island is 17 km from north to south and 14 km from east to west in the middle of Kyushu and Tsushima.

Fukashima, the southernmost island in Oita Prefecture, is a small island with a population of about 30 people, located about 9 km south of Kamae Port. There are nearly 100 cats on the island, but most of them are not domestic cats, but island cats. Two islands, one in the south and the other in the north, are connected by a central sandbar that looks like a gourd from the air. You may even encounter dolphins and turtles while traveling on the island. Underwater, you’ll find dynamic terrain, beautiful coral reefs and colorful soft coral beds.

Like a fault line, there is a mix of hard and soft corals on the monolithic rock. The depth ranges from 5-9 m, and the colony extends over more than 1 km in a straight line, with side holes next to the monolith allowing swim-throughs in some areas. Hard and soft corals coexist, and this type of landscape is rare in Japan. Sometimes rays, which can grow to over 2 meters, can be found hiding in the side holes. The scenery in shallow areas where light shines through is extremely beautiful.

Swim the mid-water to the tip with the coral ridge on your right, and you may see a large school of Japanese horn sharks descending from above. Large stingrays and turtles live in the neighboring waters, so you may be lucky enough to see them. After waiting for the school at the tip, you will see a gentle slope with a carpet of soft corals, gradually getting shallower and shallower until you reach the 5-meter safety stop, where kibibinago (sand eel) and other fish hang out. After the safety stop, we cross the natural maze created by the ridge and return to the boat.
