This discovery has sparked significant controversy for over 30 years.
In 1985, while working in the waters near Yonaguni Jima, a Japanese diver accidentally discovered a massive ancient stone structure. This stepped construction, with carefully chiseled edges, resembles pyramids. It was subsequently named the Yonaguni Architectural Complex.
Scientists have yet to determine how the pyramids and steps at the Yonaguni Monument, which is located off the coast of Yonaguni, Japan, were formed.
The origins of the Yonaguni Monument, an underwater architectural complex that includes stone steps and pyramids, located off the coast of Yonaguni, Ryukyu Islands, Japan, have been a subject of debate for many years.
The pyramids here rise to a height of 27 meters, composed of sandstone and mudstone. They are believed to have formed at the end of the Ice Age, about 10,000 years ago, when the area was still above sea level.

The structures here are made from intact hard rock.
Scientists have been unable to explain how this city came to be beneath the Pacific Ocean. Many believe that the pyramids are products of extraterrestrial beings, while others assert that they are man-made structures. Masaaki Kimura, a professor at the University of Ryukyus in Okinawa, Japan, claims that the Yonaguni Monument is a product of ancient civilizations, as there are many artificial structures along with pottery, stone tools, and hearths found in the area.
However, geologist Robert Schoch argues that the structure formed naturally. “I do not believe that any of the large structures or formations there are artificial steps; they are all natural. They are simply layers of sandstone, the tendency of fracturing on a long plane, creating very straight edges, especially in a region with many faults and seismic activity,” he stated.
Some experts believe that this underwater structure could be remnants of Mu, a legendary Pacific civilization rumored to have been submerged by ocean waves.
Subsequently, divers discovered long roads, large boulevards, massive stair structures, archway structures, and gigantic stones that were precisely and meticulously carved. Ten additional structures were found at Yonaguni, including a castle, five temple-like structures, and something resembling a gigantic stadium. Interestingly, all of these constructions are connected by waterways and roads.
Scientists have yet to explain how this site formed beneath the Pacific Ocean. How did this architectural complex disappear, and what happened to all the people who lived here? This site remains a topic of controversy for over 30 years.
