Among these stories is the account of a wrecked ship with a very mysterious appearance.
Aboard the drifting vessel was a finely dressed young woman with a pale face and red eyebrows and hair. She was estimated to be between 18 and 20 years old. Because she spoke an unfamiliar tongue, those that encountered her were unable to determine from whence she came. In her arms she clutched a plain wooden box that appeared to be of great value to her, as she would allow nobody to approach it.
Other Edo-period documents describe variations of this mysterious encounter. Toen Shousetsu (1825), a book by Kyokutei Bakin (who is most famous for his 106-volume samurai epic Nansou Satomi Hakkenden) tells the story of the same encounter, referring to the strange vessel as the utsuro-fune ("hollow ship"). Another variation of this tale appears in Ume no Chiri (1844), penned by a relatively unknown author named Nagahashi Matajirou. A thorough analysis of these two variations of the story can be found in a translated article by Kazuo Tanaka titled "Did a Close Encounter of the Third Kind Occur on a Japanese Beach in 1803?"
Contemporary fans of the paranormal know this ship as the Edo-period UFO.
