Iki Island

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. The dynamic roots, colorful coral, and plankton carried by the current attract much fish. There is also a point where there are many mysterious megaliths that look like they were carved out by humans.

Brightly colored soft corals and various seaweeds are the charm of the Genkai Sea. In the fall, you'll often see huge schools of yellowtail, flathead mackerel, groupers, grasshoppers, bristletoe, and takabae, as well as schools of stingrays and huge mallard rays. Etisian jellyfish may also make an appearance in winter.
