Imazuni

Dogtooth tuna and bigeye trevally schools a short ride from port.

Imazuni is a giant, complex wall close to port on Kume Island, rising from beyond 25 m and hung with red fan corals. The water around it barely moves, and the dive pairs a reef face full of fairy basslets with open-water fish: dogtooth tuna and schools of bigeye trevally come in even though the boat ride is short.

The dive

The wall emerges from over 25 m and is cut into a complex face of folds and features. Red fan corals grow along it, with clouds of fairy basslets around them. The current is almost nil, and dogtooth tuna and schools of bigeye trevally come in from open water to the wall.
