About this episode

The episode explores Japan's oldest UFO mystery involving the Utsuro-bune and its implications on folklore and cultural perceptions of outsiders.

n 1803, a strange round vessel washed ashore on Japan’s Pacific coast. Inside was a woman no one could understand, covered in unfamiliar symbols and clutching a mysterious box she refused to release. Known as the Utsuro-bune, this story is often described as Japan’s oldest UFO mystery. But is it evidence of an alien encounter—or a perfect example of how folklore, fear of outsiders, and imagination collide? Join Shea and Jason as they unravel the history, sources, and skepticism behind one of Japan’s most enduring mysteries.
