Hammerhead Rock
★★★★☆
(171)
The westernmost island in Japan. It’s closer to Taiwan than Ishigaki Island. It takes about 45 minutes from Ishigaki Island to reach by plane. The highlight of this island is the high chance of seeing hammerhead sharks. Among them, this is the point where the rocks, like buildings, stand vertically from the bottom of the sea at a depth of 35 meters.
In addition to schools of hammerhead sharks, you'll find big fish such as bluefin tuna, schools of bluefin trevally and barracudas, and tornadoes of bigeye trevally. Marlin tuna, whale sharks and dolphins are also sometimes seen here.
