Japan's Mysterious Submerged Stone Structures
by Laura Lee

Man-made, made by Nature, or did humankind finish what Nature started? These enigmatic, sunken stone structures off Okinawa, Japan, located 60 to 100 feet beneath the ocean surface, have the Japanese wondering if their homeland was once part of the lost continent of Mu. Stone terraces, right angled block and walls, and stone circles encompassing hexagonal columns look intriguingly, if not conclusively, man made. A few more clues: an encircling road, what might be post holes supported long-gone wooden structures, what look like cut steps, and castles with similar archietecture located nearby and still on land. The two sites that are getting the most attention: near the city of Naha is Okinawa is what looks like a wall, with a coral encrusted right angled block. Another, just off the southern end of the tiny island of Yonaguni, the southernmost island of Japan, is an extensive site, with five irregular layers that look like ceremonial, terraced platforms. There are eight anomalous, underwater sites found to date.

Two of Japan's leading researchers on the sites are Kihachiro Aratake, who first discovered the Yonaguni site, and Prof. Masaaki Kimura, a marine geologist with the University of the Ryukyus in Okinawa. Prof. Kimura has spent several years studying all eight sties, especially Yonaguni, which was found 13 years ago, in 1985. Kimura believes these are monuments made by man, left by an unknown civilization, perhaps from the Asian mainland, home of our oldest civilizations. He reasons that if the five layers on the Yonaguni site had been carved by nature, you would find debris from the erosion to have collected around the site, but no rock fragments have yet been found. He adds that there is what look like a road encircling the site as further indication it was used by man. He believes building this monument necessitated a high degree of technology, and some sort of machinery.

How to date these sites? A few possible scenarios have been suggested. The sites may have been submerged when sea levels rose at the end of the last Ice Age as the continental ice sheets melted. Or, as Japan sits on the Ring of Fire, tectonic activity might have caused subsidence of the land. Or perhaps a combination of subsidence and inundation from rising sea levels, or some catastrophic event, dropped it, intact and upright, into the ocean. Teruaki Ishii, a professor of geology at Tokyo University, believes the site is partly man-made, partly natural, and suggests a date of 8,000 B.C., contemporary to the ancient civilizations of Mesopotamia and the Indus Valley. Others have suggested a date of 12,00 years.
