#ancienttechnology #ancientstructure #archaeologicalunderwater The Yonaguni Monument, also known as “Yonaguni Submarine Ruins“, is a submerged rock formation off the southern coast of Japan. It lies approximately a hundred kilometres east of Taiwan. The sea off Yonaguni is a popular diving location during the winter months because of its large population of hammerhead sharks. In 1986, while looking for a good place to observe the sharks, Kihachiro Aratake, a director of the Yonaguni-Cho Tourism Association, found something strange. In the seabed, he saw formations that strongly resemble architectural structures. Since then, multiple geologists from Japan and around the world have gone on expeditions to the monument and studied it.
