Yonaguni is a small, remote and untouched island in the prefecture of Okinawa. In the diving world, Yonaguni is known for the chance to dive with hammerhead sharks during the winter months as well as its mysterious Underwater Monument discovered in 1986 by Kihachiro Aratake. The waters there are said to be the third clearest in the world. Moreover, there is a variety of whale sharks, dogtooth tunas, marlins along with 18 meters of coral. A never ending coral and amazing subtropical fish is a wonderful sight that divers all over the world wish to see once in their lifetime.
The Yonaguni Monument consists of medium to very fine sandstones and mudstones which are said to have been deposited about 20 million years ago. Most of the formations are connected to the underlying rock mass. Some of those who have studies the formation of Yonaguni Monument suppose that it is most likely a natural formation, possibly used and modified by humans in the past. On the contrary, the others state that the features are man-made due to the flat parallel faces, sharp edges and mostly right angles. Among the formations, “Underwater Ruins” have one of the most magnificent scenery, especially the wave patterns which can hardly be seen from anywhere else. Divers and tourists are surely to be touched by ancient monuments such as the tall Twin Megaliths, the Turtle formation, the Stairs, the Castle gate and the Place of worship deep under the sea.
Though out the year, visitors can enjoy the subtropical island feeling and the fascinating diving thanks to many kinds of activities which can offer the best experience ever. With the four-season climate, people can see different fishes in different time of the year. In the spring, cuttlefish and anemonefish lay egg in March and April respectively. In the autumn, cowry shells mate and lay eggs in October, and jawfish make nest in November.
