Yonaguni Monument

★★★★☆ (96)

The Underwater Ruins were discovered by a local diver in 1986 and is a popular diving spot in Yonaguni along with hammerhead sharks. It’s about 15 minutes from the port. A huge staircase-shaped wall spans about 250m east-west and 150m north-south to form the ruins.

You could spot hammerhead sharks and lots of reef fish.
