About this dive site

This dive site, Iki Island, is nestled in the Genkai Sea between Kyushu and Tsushima, Japan. It is renowned for its vibrant underwater topography, featuring dynamic roots and colorful coral formations. A unique highlight includes mysterious megaliths, resembling human-carved structures, adding an archaeological intrigue to the dive experience. While specific navigation details aren't provided, divers can expect to explore varied reef structures and potentially drift along with nutrient-rich currents. The plankton-rich currents create a thriving ecosystem, attracting a diverse array of marine life. Divers can expect to encounter huge schools of yellowtail, flathead mackerel, groupers, grasshoppers, bristletoe, and takabae. Schools of stingrays and impressive huge mallard rays are also frequently observed. The soft corals are brightly colored, complementing various seaweeds that contribute to the Genkai Sea's underwater charm. In winter, Etisian jellyfish may also make an appearance. The fall season is particularly rewarding for divers, offering spectacular sightings of large schooling fish like yellowtail and groupers, as well as rays. Its shallow maximum depth of 12 meters and an average depth of 6 meters make Iki Island highly suitable for both beginners and experienced divers. Snorkelers and freedivers will also find the site appealing due to its rich marine life and accessible depths, making it an excellent all-around destination for underwater enthusiasts.
