With a coastline of 34,000 km (21,000 mi), Japan is the diving world's best-kept secret. 

Lying a thousand miles south from the Tokyo, the subtropical Okinawan Islands couldn't be further from the traditional image of Japan. With white sand beaches, crystal clear waters and an array of marine life to rival the Great Barrier Reef, this truly is an island paradise.

In the waters surrounding Yonaguni Island lies one of the diving world's biggest mysteries. Whether or not you believe the story that they are the remains of an enigmatic civilisation predating the pyramids, the Yonaguni stones make a truly fascinating dive!
