The Devil’s Sea: Japan’s Bermuda Triangle and the Ships Said to Vanish There
In September 1952, a Japanese survey vessel sailed from Tokyo toward an active submarine volcano south of the Izu Islands. Kaiyo Maru No. 5 carried twenty-two crew members and nine scientific personnel. Its assignment was not to investigate a paranormal triangle or a series of vanished ships. It was sent to study Myojinsho, a newly erupting volcanic feature that had briefly formed an island above the sea before sinking beneath it again. The ship made its last reported voyage contact on the evening of September 23. By the following day, it had disappeared. Searchers later found floating wreckage, but no survivors. Subsequent scientific studies examined tsunami gauge records, underwater acoustic evidence, eruption observations, and volcanic material associated with debris. Together, those records strongly support a catastrophic submarine eruption as the cause. Yet the final minutes remain unwitnessed. No surviving crew member described the ship’s position, its damage, or whether blast effects, tsunami waves, or both caused its destruction. Years later, a separate vessel briefly lost radio contact in the same broad region and was found safe. Newspaper coverage, then popular books by Charles Berlitz, helped turn separate incidents into the story of Japan’s Bermuda Triangle. This episode follows the documented timeline, the evidence behind the volcanic explanation, and the narrow uncertainty that remains after a real maritime disaster became part of a much larger legend.
