Near Tokyo, Japan being encounter — February 22, 1803

The utsurobune, or hollow-ship, story concerns a strange vessel said to have reached the Hitachi coast in 1803. Edo-period manuscripts describe villagers finding a young foreign woman inside a rounded boat with unusual windows and markings. She reportedly had pale skin and reddish hair and eyebrows, spoke an unfamiliar language, and guarded a wooden box. Versions give different details of her clothing and the boat’s construction. The familiar saucer-like image comes from illustrated historical texts, including collections of unusual stories assembled after the supposed encounter. These are not photographs or a contemporary investigation of a flying machine. The vessel drifts ashore in the story; it is not described making an aerial landing. Its strange passenger is a woman, not a separately reported alien creature. Researcher Kazuo Tanaka has compared the surviving versions, their drawings, and possible locations in modern Ibaraki. He distinguishes uncertain folklore from the possibility of an embellished maritime incident. Other scholars have treated the narrative as fiction. Neither interpretation establishes an extraterrestrial craft, and the precise beach and chronology remain debated. The plate therefore presents an Edo-period coastal legend, with a wooden, metal-banded vessel and its passenger, rather than a confirmed spacecraft encounter.
