About this site
Cube Rock (キューブロック) is a boat dive at Futagami off Iki, dived from Itoshima on the Genkai coast of Fukuoka Prefecture, with an average depth of around 30 m and recommended for intermediate divers and above. Huge square-cut boulders lie scattered across the bottom, looking as if they had been quarried by hand. The site also holds one of Japan's densest schools of golden sweepers.
