8000-year-old Yonaguni-Jima (Japan)

Situated 68 miles beyond the east coast of Taiwan, Yonaguni Islands are a remarkable place for its rugged and mountainous coastlines. The special attraction is the submerged ruins located in the southern coast of Yonaguni: a superb 100×50x25 meters man-made artifact out of solid rock slabs stands erect at right angles. Its is estimated to be around 8000 years old, which is remarkably early for the kind of technology that has been used for carving it. Different theories exist about the possible identities of this structure.

While some say these ruins are the remnants of the missing Continent of Mu, other archeologists attribute them to be the outcome of unexplained geological processes, although, when you see the finely designed hallways and staircases, this ‘natural phenomenon' idea will appear sheer out of place.

The megalith was discovered quite accidentally by a sport diver in 1995 when he had strayed beyond the permissible limit off the Okinawa shore. The interesting thing about this massive stone building is that it had arches made of beautifully fitted stone blocks bearing resemblance with the building architectural style of the Inca civilization. Debates were rife about the ruins being associated with the prehistoric Motherland of Civilization. Surveying the ruins minutely takes time and skill because of the rough oceanic currents.
