Underwater City Baffles Archeologists

An ancient, lost underwater city mysteriously lies off the coast of Japan.

Just whom built an underwater city off the coast of Japan?

The nation state of Japan is an archipelago composed of almost 7000 islands, forming a crescent shaped string pointing towards Taiwan. Yonaguni Island represents the tip of the island chain, and this southernmost boundary marker was it’s primary claim to fame, up until 1986.

That’s when Kihachiro Aratake, a local scuba diver offering Swim-With-The-Sharks tours, accidentally discovered the sunken ruins of one of humanity’s oldest structures, a 100 foot tall pyramid shaped complex, quite a bit larger than a football stadium, just 20 feet below the ocean’s surface, off the southernmost tip of this southernmost island.

The monument appears to be carved out of natural rock formations, facing south, and features several megalithic square blocks arranged in perfect parallel format ions, with post holes and drill marks, arranged in archways, corridors, stairs, terraces, a triangular pool with drainage channels, and several unusual carvings that can be easily interpreted as a turtle, and a dragon’s head beside a human face.



It could date as far back as the last ice age 10,000 years ago, when water levels were much lower than they are today.

Who would have built such a structure or city that far back into the past?…
