About Three Rocks
Three Rocks is a Yaeyama reef site at Kayama Island with three coral-covered pillars, a sandy base, and bright fish life around the rocks. It suits relaxed boat diving for divers who like close reef structure and macro hunting, with occasional manta rays adding a bigger-animal wildcard on good days. Planning is mostly about the boat tour and the sea state rather than any technical dive demand.
