Dive-site story
Situated off the eastern coastline of Hatoma Island in the Yaeyama archipelago, this site features sprawling hard coral fields transitioning into sandy channels. Ocean currents funneling between Hatoma and northern Iriomote nourish dense colonies of branching table corals and support active reef communities. Divers typically drift along the reef contours where sea turtles and cruising pelagics frequent the drop-offs.
Extensive fields of table and staghorn Acropora coral across the upper reef
Frequent encounters with resting and grazing green sea turtles
Clear blue water typical of the open Yaeyama passage
