The Yonaguni Monuments in Okinawa, Japan, also known as 'Japan's Atlantis', are a collection of underwater monoliths 85 ft below the Philippine Sea some researchers date back 10,000 years old to the lost
continent of Mu.
While others argue they're just natural rock formations many of the structures resemble statues, animals, as well as rock carvings.
Another theory is that these are remnants of a civilization of the Jōmon people who occupied Japan up to 300 bc and are the earliest ancestors of the Japanese.
