Yonaguni is a small island south-west of Okinawa in the Japanese archipelago. In 1988, scuba divers led by Kihachiro Aratake discovered an enormous stone structure on the seabed off the coast of Yonaguni.
The structure lay more than 75 feet below the surface. Investigation showed it was 600 feet long, 450 feet wide and 90 feet high. The locals decided it was a natural formation.
Ten years later, the experts weren't so sure. The first geologist to investigate the site was Professor Masaki Kimura of Ryuku University on Okinawa. In April 1998, he discovered a structure divided into five distinct layers and decided it had to be manmade. It is easy to see why. Underwater photographs and video footage reveal a stepped, ziggurat-like monument of extraordinary proportions.
Each step is about 3 feet high with clean edges and sharp angles. There is also an archway and two parallel monoliths among other intriguing features like drainage channels. Further investigation led to the discovery of smaller satellite ziggurats near the main edifice.
Each is about 30 feet wide and 6 feet high. Each appears to be constructed of stepped slabs. Divers also found what looks like a road surrounding the main structure.
Robert Schoch, the American geologist who re-dated the sphinx, dived to examine the Yonaguni Monument and later commented that while natural water erosion and rock splitting might possibly produce a structure of this type, he had never seen anything quite like it before.
Professor Kimura was even more forthcoming. He maintained bluntly that if the sharp steps were the result of natural erosion there would be debris on the seabed surrounding them. In fact, there is none.Conventional dating puts this Japanese culture at a time when scientists thought only primitive hunter gatherers worked on the land and had very limited knowledge. We know this is proof of a flood, and of the global scale that it occured in Noah's time.
