Off the coast of the small japanese island Yonaguni lies a rock formation that has striking ressemblances to remains of submerged cities elsewhere. It was discovered in 1986. But no source from history has so far proven the existence of a city in this location and it is deputed whether the Yonaguni monument is in fact nothing more than a bizarre fancy of nature.
