The Yonaguni Monument

Japan is a land of contradictions; a land of mystery where the traditions of centuries long gone sometimes have to make way for the challenges of today.  But there is one mystery which is still around to stump local archaeologists and geologists.  Deep underwater off the coast of Yonaguni, near Okinawa, is a massive rock formation.  Discovered in 1986, a diver came across an unusual underwater structure.  There are terraces and ramps, as well as a pyramid structure as large as 600 feet wide and 90 feet high. There is also five separate levels of stone which some experts say appears to be a road surrounding the formation

Some scientist have recreated what the structure would look like if built on land and one wonders what this structure was really used for?  The undercurrent is dangerous but that doesn't stop local divers from exploring the different levels.  

Is this another lost Atlantis uncovered?  Maybe millions of years ago water didn't cover that part of the world and this was the beginning of a great ancient city?  Or maybe it was the foundation of some unknown civilization that was destroyed during a time when ice melted and covered most of the earth with water?

Or maybe it's simply a bunch of rocks thrown together by the currents.  I'm a dreamer, so my bet is on the ancient civilization, but you be the judge...
