In 1803, during Japan's Edo period, a UFO-like disc-shaped vessel allegedly washed ashore on the coast of Ibaraki, and a foreign woman emerged from inside. This incident, recorded in official Edo-period documents, has now been turned into official merchandise by Japan's National Archives, an unexpected turn for one of the country's most serious historical institutions.

Japan's National Archives Launches Mystery Merchandise

The National Archives of Japan is the guardian of the nation's historical memory, housing approximately 1.7 million records including the original Japanese Constitution and vital government documents dating back to the Meiji era. Yet among their official merchandise offerings lies one product that stands dramatically apart from the rest.

"Double Pocket File: The Barbarian Woman of Utsuro-bune (A5)" – 400 yen.

This clear file features an actual illustration from "Kōken Zuihitsu" (Hirokata's Essays), a document compiled by the scholar Yashiro Hirokata, depicting a bizarre vessel that washed ashore in Hitachi Province (modern-day Ibaraki Prefecture) in 1803, carrying a woman who spoke an unknown language.

What is the Utsuro-bune Legend?

The Utsuro-bune (literally "hollow ship" or "empty vessel") legend describes an incident said to have occurred on February 22, 1803, at a beach called "Harayadori" in Hitachi Province. Fishermen spotted a strange object drifting offshore and pulled it to shore, discovering a disc-shaped craft resembling a kōgō (an incense container with a lid).

According to "Kōken Zuihitsu," the vessel had the following characteristics:

  • Approximately 5.5 meters in diameter (about 18 feet)
  • Glass panels on top allowing visibility inside
  • Iron plates covering the bottom
  • Mysterious characters inscribed within

Inside sat a beautiful woman in unfamiliar clothing. Her hair and eyebrows were red, her face was pink, and she wore white artificial hair that hung long down her back. She clutched a 60-centimeter square box that she refused to release. Unable to communicate, the woman simply smiled at those who approached.

A village elder speculated she was "the daughter of a foreign king, exiled for the crime of adultery, and the box surely contains the severed head of her lover." Fearing the complications of reporting to authorities, the villagers eventually placed the woman back in the vessel and pushed it out to sea, a haunting conclusion to this mysterious encounter.

Why Is It Called "Edo-Period UFO"?

This legend has garnered worldwide attention because its description bears striking similarities to modern UFO reports.

More than 140 years before the 1947 "Arnold Incident" that introduced the concept of flying saucers to public consciousness, Japan had recorded this disc-shaped vessel. UFO researchers and mystery enthusiasts have dubbed this "Japan's Roswell Incident." Professor Emeritus Kazuo Tanaka of Gifu University has dedicated over 20 years to researching this legend, identifying the actual location "Hitachi Harashari-hama" (now Sharihama in Kamisu City) from multiple historical documents, evidence that this may be more than mere fiction.

To date, references to this incident have been confirmed in 11 types and 14 editions of historical documents, including "Toen Shōsetsu" (Rabbit Garden Tales) by the famous author Kyokutei Bakin, "Ume no Chiri" (Dust of Plum Blossoms), and "Hyōryūki-shū" (Collection of Drift Records).

The Unexpected Turn for Official Government Merchandise

The National Archives of Japan has traditionally offered historically orthodox merchandise: clear files featuring the "Heisei Declaration" and "Reiwa Declaration," Meiji-era railway maps, and botanical illustrations. The sudden appearance of a product themed around "Edo-period UFO suspicions" represents a surprising new direction for this prestigious institution.

Importantly, "Kōken Zuihitsu" is housed in the National Archives' Cabinet Library collection, and this institution is reportedly the only place in Japan where the original document can be viewed. This means the organization that holds the sole original manuscript has commercialized its own material, making this the genuine "official" Utsuro-bune merchandise.

The Fusion of Japanese Historical Mystery and Pop Culture

Utsuro-bune has been incorporated into various forms of pop culture over the years. In 2016, reproductions of the historical documents were displayed at the Mori Art Museum's "Universe and Art" exhibition, where novelty items like the "Utsuro-bune Rice Bowl" became popular. In 2023, the Jōyō Historical Museum in Mito City, Ibaraki Prefecture, hosted the "Mysterious World: Utsuro-bune" exhibition, featuring works by local artists alongside historical documents.

A monument and playground equipment shaped like the Utsuro-bune was once installed at Ōtake Beach in Hokota City, Ibaraki Prefecture. In Ibaraki, the "homeland" of this legend, the Utsuro-bune is increasingly recognized as a regional historical and cultural resource.

The decision by a public institution like the National Archives to commercialize this legend represents an attempt to balance the scholarly value of historical documents with entertainment appeal, creating new pathways for public engagement with history.
