The Secrets Of The Prehistoric Yonaguni Monument In Japan

The "Yonaguni Monument" or also known as the "Yonaguni Submarine Ruins" is a prehistoric submerged rock formation that is formed in weird large clusters up to 5 floors high and it is believed to be a completely man-made artificial structure.

The terraced formations were discovered off the coast of Yonaguni Island in Japan by the divers in 1986 since it's a popular diving location during the winter months because of its large population of hammerhead sharks.

Apart from its strange appearance, there were found some artefacts that prove the existence of people in those places. Marine geologist Masaaki Kimura from the University of the Ryūkyūs, whose group was the first to visit the formations claims that the formations are man-made complicated monoliths that are actually the ruins of a Japanese Atlantis—an ancient city sunk by an earthquake about 2,000 years ago. Whereas some even strongly believe these rock formations were man-made from the prehistoric era. If we suppose this claim, the monument structure belongs to the preglacial civilizations.

The seabed formations resembling architectural structures consist of medium to very fine sandstones and mudstones of the Early Miocene Yaeyama Group believed to have been deposited about 20 million years ago.

The most attractive and strange feature is a rectangularly shaped formation measuring about 150 by 40 metres and about 27 metres tall and the top is about 5 metres below the sea level. This is the largest structure which looks like a complicated, monolithic, stepped pyramid.

Some of its details are said to be:

• Two closely spaced pillars which rise to within 2.4 metres of the surface
• A 5 metres wide ledge that encircles the base of the formation on three sides
• A stone column about 7 metres tall
• A straight wall 10 metres long
• An isolated boulder resting on a low platform
• A low star-shaped platform
• A triangular depression with two large holes at its edge
• An L-shaped rock

On the other hand, some of those who have studied the formation, such as geologist Robert Schoch from the Boston University, Oceanic Geoscience Professor Patrick D. Nunn from the University of the South Pacific, suggest that it is either a completely natural formation or it was a natural rock structure that was later possibly used and modified by humans in the past.

Therefore there is a great debate about whether the "Yonaguni Submarine Ruins" is completely natural, a natural site that has been modified, or a man-made artefact. However, neither the Japanese Agency for Cultural Affairs nor the government of Okinawa Prefecture recognises the features as important cultural artefact and neither government agency has carried out research or preservation work on the site.

Actually, the Yonaguni Monument reminds us of another mysterious and more sensational undersea structure, The Baltic Sea Anomalywhich is believed to be a wreck of ancient alien-ship. You could read the story of this strange undersea mega-structure here.

However, if you are so fascinated with the lost undersea cities or the strange ancient structures, you could visit the Yonaguni Island. No doubt the island is bound with a lot of beautiful sea scenes, quiet nature and the historical mysteries. This 28 sq. km island is also known as Dounan in the local language, it's located 125 km from Taiwan and 127 km from the Ishigaki Island and it is the westernmost point of Japan.
