The Yonaguni Pyramid is located just off shore on the South side of Yonaguni Island. Yonaguni-jima is one of the Yaeyama Islands and the westernmost inhabited island of Japan. It is the last of the islands in the Ryukyu Islands chain, and lies 108 kilometers (67 mi) from the east coast of Taiwan, between the East China Sea and the Pacific Ocean.

History :

During the last ice age, Yonaguni was part of the Chinese mainland. In the 12th century, it was incorporated to the Ryukyu Kingdom. In the 17th century, it was incorporated into the Japanese han of Satsuma. By 1879, the island was formally incorporated into Japan. 

Until the early 20th century, Yonaguni was part of the larger Yaeyama village, which included the neighboring Yaeyama Islands. In 1948, it became an independent village. From 1945 to 1972, it was occupied by the United States and was then returned to Japan to form a part of Okinawa Prefecture. 

The Yonaguni Monument is a massive underwater rock formation off the coast of Yonaguni, the southernmost of the Ryukyu Islands, in Japan. While many archaeologists and geologists believe that it is a natural formation, some hold the view that some of its features are man-made.

Mysterious Underwater Pyramid (by Suzanne Hayes) : 

A mysterious undersea pyramid structure off the coast of Japan causes controversy – is this a natural geological phenomena or a man-made structure which changes the history books as we know them?

In 1986, a diver near the island of Yonaguni Jima, off the southern tip of Japan (around Okinawa) came across some strange structures about 25 metres below sea level. They appeared to be stepped structures with terraces and ramps. One of the largest pyramid structures is 600 feet wide and 90 feet high with five separate levels of stone blocks with what appears to be road surrounding the structure.

Tool marks and carvings have been discovered upon the stones (and documented) which indicate that they have were constructed rather than being natural stone structures. Masaaki Kimura, a marine geologist from Japan’s Ryukyus University, Japan has been studying and mapping the site for over 15 years and believes that the site is over five thousand years old – but was sunk during an earthquake two thousand years ago.

Others have estimated that the structure is far older – including Teruaki Ishii, professor of geology at Tokyo University who determined that the submergence occurred at the end of the last ice age – which was around ten thousand years ago (over twice as old as the pyramids in Egypt) – If this is the case, then our history books would have to be revised to take into account an advanced Eastern culture, more advanced than any early Western culture.

It is interesting to note that a number of tools have been discovered both on land and in the sea around the structures. Close to the pyramid structure, what is thought to be the carving of a human head has been discovered (several feet tall), along with numerous unknown hieroglyphs. The Japan Times reported the following story to add intrigue to the find  “In Okinawan folk-law, there are tales of traditional Gods , and a land of the Gods called Nirai Kanai, an unknown faraway land from where happiness is brought.”
