About this site
Oka Sakune (オカ作根) is a reef site off Kozushima in the Izu Islands, Tokyo, intermediate and above, with current. Its north slope is a field of cup coral where anthias swirl against the flow. Sunlight falls through the intricate reef top, and large schools of takabe pour down through it.
