Aburasumashi is a yokai said to appear at a mountain pass in Higo Amakusa. Although often depicted as a small figure wearing a straw raincoat (mino) with a potato-like head and large eyes, the original folklore describes it as a phenomenon without a definite form, appearing merely as a voice or a presence. It is known from a tale set in Kusazumigoe—a pass lying between Kawachi in Sumoto-machi and Shimoura in Hondo—which was recorded by folklorist Ryuichi Hamada in his *Amakusa-to Minzokushi* (Folklore of Amakusa Island) (1932)[1]. The "sumashi" in its name is said to mean "to squeeze" or "press" (oil) in the Amakusa dialect, suggesting the yokai has its roots in the local practice of pressing precious oil from the seeds of camellias and sasanquas.
Folklore & Legends
The tale conveyed in *Amakusa-to Minzokushi* is very brief. An old woman, taking her grandchild across the Kusazumigoe pass, reminisced about the past, saying, "Long ago around here, they say a thing carrying an oil bottle used to appear." Immediately, a voice replied, "It sti—ll appea—rs n—ow"[1]. The eeriness of this yokai lies in its formless nature, manifesting by seizing upon the words of anyone who utters its rumor.
This simple, local Amakusa lore became nationally known when Kunio Yanagita recorded it in his "Yokai Meii" (Glossary of Yokai Names) serialized in the magazine *Minkan Densho* (Folk Lore)[2]. Furthermore, Shigeru Mizuki introduced it in *GeGeGe no Kitaro* wearing a straw hat and raincoat, establishing today's image of the potato-headed, large-eyed creature. On the Kusazumigoe pass trail, a stone statue resembling a headless Jizo remains as the "Grave of Aburasumashi," with nearby gravestones bearing era names from Tenmei and Bunsei. It was rediscovered around 2004 during a yokai boom and is now maintained as a historical site by Amakusa City[3].
The core of the aburasumashi is not its "appearance" but its "response." The moment someone mentions a rumor about it at the pass, it replies, "I still appear now" ── the very act of speaking becomes a summoning. It is a yokai that possesses words. The imagery of the straw raincoat, hat, and potato head was a later creation popularized by Shigeru Mizuki; the original Amakusa lore was purely about a voice and a presence.
The backdrop to this legend is the local lifestyle of pressing "katashi oil" from the seeds of camellias and sasanquas in Amakusa. A leading theory suggests that the warning against those who stole or wasted the scarce oil crystallized into the shadow of a figure carrying an oil bottle in the darkness of the pass, sharing a lineage with oil-related apparitions like Aburabo and Aburabozu across Japan. While linking the nameless stone statue at Kusazumigoe in Sumoto to its "grave" is a modern reinterpretation, it serves as an excellent example of local memory coming to inhabit a physical object.
Character Profile
This section is our own creative profile for storytelling. It is not historical fact or scholarship.
A creature of few words, it seizes upon human carelessness and rumors to respond unexpectedly. Rather than causing direct harm, it possesses a quiet, cynical disposition, preferring to send a chill down one's spine to assert its existence.
Word Possession ── Seizing the ending of a rumor spoken about itself, it responds instantly without showing a physical formManifestation as Presence ── Lacking a definite body, it manifests only as a voice, the smell of oil, or an eerie presenceDominion Over the Pass ── It claims the Kusazumigoe pass as its territory, lying in wait for travelers to let their guard down
Weaknesses
It rarely appears to silent travelers who do not speak rumors. Because it has no concrete form, if the belief or the telling of its story ceases, its existence fades.
Habitat
The mountain pass (Kusazumigoe) in Sumoto, Amakusa Shimoshima. The darkness of the evergreen broadleaf forest where camellias and sasanquas grow thick.
