The sea surrounding Yonaguni is known for being one of the few places in the world to encounter hammerhead sharks. There is even a chance to see a group of over 100 hammerheads swimming, especially off the southern coast of Irizaki, the western end of the island, a place divers worldwide yearn to visit. The high probability of encountering hammerhead sharks comes during the winter season between November and April, but with other popular spots like the Underwater Ruins, Light Palace, and Double Arch, divers are visiting the island throughout the year.

Submarine Topography

A group of megaliths lying on the seabed of Yonaguni Island have a total length of approximately 100 meters, a width of approximately 60 meters, and a height of approximately 25 meters. How the mysterious topography of steps, stone pillars, and other structures that appear to be man made were formed remains under investigation. While there has been a map created with names assigned to each spot, there are supposedly other unknown features as well. Were they naturally formed or built by hand?
