Yonaguni structures

They are a set of structures discovered on the Japanese island of Yonaguni around 1985 by the Japanese diver Kihachiro Aratake, who found them by chance. It is a megalith, which was probably out of the sea during the ice ages, with shapes on its surface that seem to have been carved by humans.

There has been much speculation about the origin of this monument as it is called in Japan. For various geologists and historians, the structures could have a natural origin, while others argue that these structures show artificial and human work, at least in part.

On the pseudo-archaeological side, other authors suppose that Yonaguni was part of the Mu civilization, whose fate would have been similar to that of Atlantis or Thule

Some time after its discovery, a group of scientists led by Misaki Kimura, from Ryukyu University, confirmed its existence. According to Professor Kimura’s study, the natural structure was at some time modified by humans. This would give strength to the speculations according to which Yonaguni could have been part of the civilization of Mu and that it later disappeared, just like Atlantis or Thule.

It would be a construction carried out at least 10 millennia ago, which would make it, together with the Göbekli Tepe sanctuary, the oldest known architectural structure, long before the first buildings in Mesopotamia, Egypt, India and China.
