Folklore rarely recounts anything that really happened, but when a story is told through three different texts, it's hard to dispute some fantastical, mysterious events. Such is the case with the "Utsuro-bune" that showed up in Japan in 1803. The tale provides more questions than answers.
According to the legend, a hollow ship reached the shores in the Hitatchi province with a beautiful young woman inside, along with many texts written in an unknown language. The woman had red hair and eyebrows and was elongated by artificial white extensions, which could have been made by white fur or white-powdered textile streaks. The mentioned hairstyle could never be found in any literature.
The woman was friendly, though off, and held onto a quadratic box made of a pale material that nobody was allowed to touch. She didn't speak a lick of Japanese and couldn't communicate with the fishermen that found her. Eventually the fishermen returned her to the Utsuro-bune and sent it back into the sea, since they believed it was her predetermined destiny.
Ufologists claim that this story represents solid evidence for an alien visit to the small Japanese town. Drawings depicting the woman and Utsuro-bune even have a very saucer-like appearance.
