Offshore structure near Japan's coastline: Is it a product of nature or human engineering?
The Yonaguni Monument, a large underwater rock formation located off Japan's westernmost island, has been a subject of fascination and debate since its discovery in 1986. This mysterious structure, approximately 150 meters in length and 40 meters in width, has sparked intrigue with its stepped, terrace-like features and straight edges that some interpret as signs of an ancient stepped pyramid[1].
The monument, which sits in open water and can only be reached by dive, has been a captivating enigma for many. Its unusual shape, coupled with its setting and silence, has held a grip on the imagination[7]. Divers often find the formation disorienting due to its regular lines and geometric shapes[8].
However, the consensus among many geologists and archaeologists leans towards the Yonaguni Monument being a natural geological formation shaped by underwater currents and natural fracturing, rather than a submerged ancient structure[1][3]. The rock formation is composed of solid bedrock rather than worked blocks, and the straight lines and terraces could result from natural tectonic and erosional processes[1].
Proponents of the man-made theory suggest that the structure could be 5,000 to 10,000 years old, potentially linked to lost civilizations or early advanced cultures. However, no concrete archaeological artifacts or unequivocal signs of tool use have been found to support it being man-made[3].
The lack of artifacts matters significantly in the assessment of human occupation at Yonaguni. Isolated monoliths rise from the seabed like carved sentinels within the Yonaguni Monument, but no such evidence has surfaced to confirm human intervention[6].
One side of the Yonaguni Monument features a long trench running parallel to a clean rock face, which some interpret as evidence of human carving. However, many geologists believe that this feature is entirely natural, formed by tectonic uplift and erosion[5].
Despite the lack of definitive evidence, the debate surrounding the Yonaguni Monument continues. Marine geologist Masaaki Kimura is a proponent of the theory that the underwater formation may have been modified by human hands. On the other hand, most professional archaeologists have kept their distance from the site, viewing it as a modern invention used to dramatize the mystery[2].
While the Yonaguni Monument remains a captivating mystery, it is essential to approach it with a critical eye. Until definitive proof of human origin is found, it is more likely that the Yonaguni Monument is a natural geological formation shaped by underwater currents and natural fracturing, rather than a submerged ancient structure[1][3].
