Mystery underwater formation near Japan's shore: Is it a product of nature or human design?
The Yonaguni Monument, an intriguing underwater rock formation discovered off the coast of Yonaguni Island, Japan, has been a subject of debate among marine geologists and fringe theorists since its discovery in the mid-1980s. This mysterious structure, stretching over 165 feet in length and 65 feet in width, has sparked speculation about its origin, with some arguing it is a natural geological formation, while others believe it could be the remains of an ancient, submerged civilization.
Discovered by local dive tour operator Kihachiro Aratake, the Yonaguni Monument has shapes with many straight lines and apparently carved features, which have led some to interpret as evidence of human construction. Masaaki Kimura, a marine geologist, is a proponent of this theory, suggesting the structure might be the remnants of a sunken city, potentially dating back 5,000 years. Some even speculate it might be connected to mythical civilizations like Mu or Lemuria.
However, many researchers maintain that the formation's features can be explained by natural fracturing of solid rock and erosion. They argue that the monument appears to be a single rock mass rather than assembled blocks, which weighs against the idea of human construction. The most widely accepted view among geologists is that the Yonaguni Monument is entirely natural, formed by tectonic uplift and erosion.
The structure of the Yonaguni Monument includes massive ledges, flat platforms, and vertical faces that appear artificial. Some edges even seem machined. However, critics of Kimura's work argue that his interpretations rely too heavily on visual suggestion, with what appears to be a carving potentially being the result of rock weathering.
Despite the intriguing shapes and features, the lack of artifacts matters, as people tend to leave things behind when they build something. Local oral traditions in the Ryukyus do not mention a sunken city off Yonaguni, further adding to the mystery.
The site may be a case of pareidolia, where people naturally spot patterns, even when they aren't intentional. Other submerged sites, such as those off the coast of India and Greece, have revealed ancient ruins buried beneath the sea, adding fuel to the debate.
However, the Yonaguni Monument is not recognized as a cultural heritage location by the Japanese government, and no formal excavation has ever taken place. The isolated monoliths that rise from the seabed like carved sentinels remain a captivating enigma, inviting further exploration and research to unravel the truth about this mysterious underwater formation.

[1] The Yonaguni Monument, a subject of debate, has been studied by scholars in archaeology, marine geology, environmental science, and technology, as exemplified in the works of Kimura (2007) and Zhang (2015).
[2] Some archaeologists and scientists question the assumption that the Yonaguni Monument is an artifact of ancient civilizations, suggesting it could be a natural formation or the result of environmental-science processes like climate-change and erosion.
[3] The absence of artifacts or evidence of human habitation, together with the lack of historical records from local oral traditions, creates a challenging scenario for those advocating for the monument as the remains of a lost civilization.
[4] Data-and-cloud-computing and advanced scientific techniques in underwater exploration and imaging might help delve deeper into better understanding the Yonaguni Monument's origins, potentially providing new insights for solving the mystery that lies beneath the waves in the midst of environmental changes.
