Kuchisake-onna (口裂け女)

§Appearance

Kuchisake-onna (口裂け女, くちさけおんな) appears as a tall woman whose face is partially covered by a surgical mask, cloth, fan, or handkerchief. At first she can pass in the modern streetscape as merely unusual. The revelation comes when she removes the covering and shows a mouth slit from ear to ear. In some tellings the wound is surgical, in others bloody and raw, and in some it is lined with too many teeth.

Her image is unusually modern for a yōkai. The mask, the city street, and the direct approach to schoolchildren or solitary pedestrians place her in everyday contemporary space. Even so, the underlying structure is older. The ordinary female figure becomes terrifying at the instant the face ceases to guarantee humanity.

§Interactions

Kuchisake-onna approaches a victim and asks a deceptively simple question, usually Watashi, kirei?, 'Am I beautiful?' A wrong answer kills immediately. A flattering answer only advances the trap, because she then reveals the slit mouth and asks again. Depending on the version, the victim is murdered, mutilated to resemble her, or stalked home and attacked later.

The folklore also preserves escape strategies. A person may answer that she looks average, claim to be in a hurry, repeat confusing phrases, or distract her with money or hard candy such as bekkō ame. These evasions matter because they make the legend interactive. Kuchisake-onna is not just seen. She forces her victims into a conversation in which every answer risks becoming the wrong one.

The modern legend is most securely tied to the rumor wave that spread through Japan in 1978 and 1979, especially after reports in Gifu-area newspapers and national weeklies. Children were escorted home, schools circulated warnings, and the slit-mouthed woman moved from rumor into national monster status. Scholars nevertheless note older precedents in Edo-period grotesque female imagery and roadside spirit lore, which helps explain why the modern figure was so readily absorbed into the yōkai field.

Later commentators, including Shigeru Mizuki and writers on contemporary folklore, treat Kuchisake-onna as a modern yōkai or urban-legend onryō. She sits at the hinge between ghost story, media panic, and traditional supernatural logic. The persistence of the legend shows how quickly modern rumor can harden into canon when it matches older narrative patterns of beauty, injury, and night-road danger.

The standard encounter is simple and relentless. A masked woman stops a passerby at night and asks if she is beautiful. If the answer fails, she kills. If the answer succeeds, she exposes the wound and asks again. Variants differ over whether the victim dies on the spot or later, but they keep the same structure of forced evaluation followed by punishment.

Origin stories also vary. In one she was a samurai's adulterous wife whose husband cut her mouth open in rage. In others she is the victim of surgery, jealousy, wartime violence, or simple rumor detached from biography. Those backstories matter less than the repeatable encounter itself. Kuchisake-onna survives because the question can always be asked again on another road.
