The Devil's Sea

The Devil's Sea

Miyake Island, Japan

The Devil's Sea, also called the Formosa Triangle, is located off the coast of Japan in a region of the Pacific around Miyake Island, about 110 miles south of Tokyo.Like the Bermuda Triangle, the Devil's Sea doesn't appear on any official maps, but the name is used by Japanese fishermen. The area is known for strange disappearances of ships and planes-at least by those in the United States.

Another myth is that, like the Bermuda Triangle, the Devil's Sea is the only other area where a compass points to true north rather than magnetic north.
One popular theory is that volcanic activity around the area, particularly an underwater volcano, could be responsible for the disappearances.
