The Yonaguni Monument is an underwater mystery off the coast of the Ryukyu Islands, Japan, discovered in 1986 by Masaaki Kimura. The massive underwater rock formation is speculated to have existed for more than 10,000 years. Yonaguni is composed of sandstone and mudstone that dates back 20 million years. Kimura claims that the site was carved thousands of years ago, when the landmass was above water and the carvings on it resemble Kaida script. A pyramid, castles, roads, monuments and a stadium can be identified within the structure. The monument maybe the remains of the Lost Continent of Mu, the Japanese equivalent to Atlantis.
