In August 1945, a Japanese fighter pilot’s final radio transmission crackled out over the Pacific south of Tokyo: the sky is opening up. Then dead air, and the plane supposedly vanished without a trace. It is the ultimate locked-room mystery set against the largest ocean on Earth.

This episode takes a deep dive into the Devil’s Sea, also called the Dragon’s Triangle, examining the anatomy of a myth: how it was born, fed by a global media machine, and ultimately dissected by cold reality. We trace the fabrications and reveal the genuinely terrifying natural forces capable of swallowing a ship whole. It matters because it shows how easily a sensational narrative can overwrite boring, nuanced facts.

• The 1955 panic began when the ship Shin’yo Maru No. 10 lost radio contact, yet it was found safe 11 days later, after which a newspaper drew an arbitrary danger zone on a map.
• Author Charles Berlitz escalated the myth across books, retroactively adding modern ships and even five 1942 military vessels to the casualty list.
• Researcher Larry Kusche proved the missing ships were small wooden fishing boats lost in violent storms, not modern ships in perfect weather.
• The research vessel Kaiyo Maru No. 5 sank in 1952, three years before the panic, killing 31 crew when an undersea volcano erupted, not vanishing into a void.
• The phrase ma no umi simply means dangerous sea and was used for waters worldwide, while real hazards like destabilized methane hydrates can sink ships in seconds without debris.
