One of the greatest mysteries in Japan is the origin and nature of underwater stone structures lying underwater off Yonaguni Island.
Japanese marine biologist Masaaki Kimura has identified ten structures off Yonaguni and a further five related structures off the main island of Okinawa.The structures include the ruins of a castle, a triumphal arch, five temples, and at least one large stadium, all of which are connected by roads and water channels and are partly shielded by what could be huge retaining walls.
In total the ruins cover an area spanning 984 feet by 492 feet (300 meters by 150 meters). Also found were a triangular bath-pool structure, two post-holes, structure similar to a dance platform inscription, castle entrance gate, ditches, staircases, a turtle-shaped relief rock, terraces and a rock inscription that appears to belong to the ancient Kaida script that was a writing system in use in the Yaeyama Islands and on Yonaguni Island before the introduction of the nation’s education system in Japan.
According to Kimura, the ruins date back to at least 5,000 years, based on the dates of stalactites found inside underwater caves that he says sank with the city.
