Japan's Mysterious Underwater Pyramids
One of the greatest mysteries of Japan is located on the island called Yonaguni and was discovered by the Japanese diver named Kihachiko Aratake in 1995, where researchers claim that the pyramids could be over 11,000 years old.

In the bottom of the sea of the island of Yonaguni hides a set of megalithic ruins covering a total of 28 square kilometers. One of the monuments is 600 feet wide and 90 feet high, totaling over 27 meters high and 182 meters wide.
Some claim these pyramids are from a civilization as old as Sumer, Egypt, India or China. Some have found similarities to Mesopotamian ziggurats, others even claim to be Atlantis, Lemuria or Mu. What do you think of this mystery from Japan?
The Devil's Sea - Dragon's Triangle
But no Umi [魔の海] is a Japanese version of the Bermuda triangle, a mysterious area in the Sea of Japan where several boats and planes have disappeared, numbers even higher than the Bermuda triangle.
In addition to the missing boats, you can find ghost ships and unmarked boats. This area is just 100km south of Tokyo around Miyake Island. The region spans Guam and the Marina Islands totaling over one million square meters.

Between 1952 and 1954 Japan lost five military vessels with a total of 700 people in the Devil's Sea, soon after it lost another 100 scientists who were sent for an investigation.
Interestingly, the Devil's Sea is at the same latitude as the Bermuda Triangle, leading researchers to believe that there is some connection or even a wormhole at the site.
The Japanese do not believe that the Devil's Sea is the most dangerous water in Japan, crediting these tragedies to natural disasters, volcanoes and other non-paranormal things. Is that you? What do you think of the devil's sea? Is it a big mystery of Japan?
The Mystery Behind the Honno-ji Incident
The famous Honno-ji incident in the Sengoku period, responsible for delaying the unification of Japan by 20 years. This is one of the most popular stories in Japan, but it also generates discussions and mysteries to this day.
People are left trying to understand the motivation behind the murder of the great Oda Nobunaga that took place in 1582. The assassin Akechi Mitsuhide was one of Oda Nobunaga's trusted and esteemed generals, and the place of betrayal was full of friends and allies and emitted security.

It is not known for sure why Mitsuhide betrayed Nobunaga. Some believe the cause was a personal grudge, fear of revolution, ambition to conquer Japan, or just wanted to protect the Imperial Court of Japan. However, the reason is a mystery, as he was killed 13 days later by Oda Nobunaga's allies.
