It is located near the Japanese coast in the Pacific Ocean and also known as Dragon’s Triangle. The Dragon’s Triangle extends as a triangle between Japan and the Islands of Bonin, including a major portion of the Philippine Sea.

The area has also been called the Pacific Bermuda Triangle, denoting its position that is precisely opposite to the Bermuda Triangle and the similarities in the “paranormal phenomena” of the area with that of the Bermuda Triangle. Such an infamous reputation for this oceanic area has been not gained contemporarily but exists for decades and even centuries if some records are to be believed. 

• To begin with, the term dragon in the other name of Devil Sea originates from the centuries-old Chinese myth about dragons existing below the water surface. According to these, the dragons under the sea attack vessels passing by to satiate their hunger, and their movement can suddenly churn up waves, whirlpools, thick fog, and sudden storms. With their emphasis on the presence of mythical creatures like dragons, these fables have made a huge impact on the legends and mysterious stories created in the years to come.
• Similarly, the Japanese name “Ma-No Umi,” which means the Sea of the Devil, was originally coined by the Japanese countrymen years ago when the stories of paranormal phenomena in the sea were popularised. The superstitions associated with the Devil’s Sea always haunted the Japanese from venturing into this part of the ocean right from centuries past.
• In the later century, especially in the 1940s and 1950s, a number of fishing vessels and over five military vessels were disappeared in the sea, in an area that lies between Miyake Island and Iwo Jima. As a result, Japan sent a research ship named Kaio Maru No.5 in 1952 to investigate the previously missing vessels that had been reported to have gone missing in the Dragon’s Triangle without any trace. However, the research vessels with 31 crew members abroad also met the destiny of previous vessels which went to the Devil’s sea. Following this incident, the Japanese government reportedly declared this area dangerous for marine voyaging and transporting goods. 
• When Ivan T. Sanderson appeared on The Dick Cavett Show to discuss his theories, expecting to go head to head with the very vocal critic, Arthur Godfrey, he was astonished to find that Godfrey had his own tales of strange occurrences to share, beginning with a report of his radio and other instruments going off while flying over the Devil’s Sea. 
• Like the Bermuda Triangle, the Devil’s Triangle area may be volatile, subject to sudden weather changes and ocean swells not yet understood. None of the incidents have been explained with sufficient proof and naturally, the legend has grown stronger with each following incident.
