Underwater Japanese Pyramids

In September 1997, Dr Robert M. Schoch, a professor from Boston University, went to Japan to examine an enigmatic structure that had been discovered in 1985 off the coast of the southernmost Japanese island of Yonaguni Jima. He had been invited by the writer, Graham Hancock, to give his opinion as to whether or not the structure was 'natural' in origin or 'man-made'. The expedition was to be filmed for a series of three television documentaries Based on his research, Dr. Kimura has espoused the view that the Yonaguni Monument is, on the whole, an artificial structure.
If this is the case, then the Yonaguni monument appears to bear testimony to a previously unknown, yet very early and highly sophisticated civilization (possibly linked to the Angkor Wat temples in Cambodia? JM).
