Kuchisake-onna (口裂け女, "slit-mouthed woman") is one of the most recognisable Japanese urban legends. Surgical mask, long hair, scissors in hand, she asks her victims a simple question: "Am I beautiful?" The trap is right there: no simple answer saves you. The name itself is clinical, three kanji for three facts, a mouth, slit, on a woman, which makes it impossible to forget.

The legend's origin
The traditional telling ties her to a woman of great beauty, the wife of a jealous samurai. Suspecting her of infidelity, he is said to have slit her mouth from ear to ear, asking who would find her beautiful now. Turned into an onryō, a vengeful spirit, she returns to inflict on others the mutilation she suffered. Like the Hannya (the woman turned demon by jealousy) or the Jorōgumo, Kuchisake-onna belongs to that recurring folklore theme: female beauty both worshipped and punished. She isn't a monster who kills for pleasure, she's a victim turned predator.
The trick question
In modern versions the scene almost always runs the same way. The masked woman approaches and asks "Am I beautiful?" If you answer no, she kills on the spot. If you answer yes, she pulls off her mask, reveals her slit mouth, and asks "Even like this?" Again, yes and no both lead to the worst. It's not an official rule, more a pattern repeated from telling to telling.
Modern folklore invented ways out. The most cited is the neutral answer, "Maa maa desu" ("you're average"), which throws her into confusion. You can also turn the question back on her, throw her hard candies (bekko-ame) that she stops to pick up, or shout "Pomade!" three times, a reference to the surgeon's smell in some variants. Running is uncertain: depending on the version, she tires over distance or runs at superhuman speed.
The 1979 panic
What makes Kuchisake-onna unique among the world's urban legends is that she caused a documented mass panic. In the spring of 1979, the rumour started in Gifu prefecture, was picked up by local then national press, and spread across the country. Children refused to go out alone, schools organised group walks home, parents formed escort patrols, and police stepped up rounds in several prefectures. According to folklorist Iikura Yoshiyuki, the legend likely served as a parental bogeyman at a time when children came home late from cram schools (juku). It spread like a virus, schoolyard to schoolyard, amplified by newspapers. It's the first purely Japanese urban legend to have a measurable public impact.
Its power rests on one detail: the surgical mask. In a country where wearing one is perfectly ordinary, any masked woman in a dark alley can become suspect. The legend turns an everyday gesture into a source of terror.
FAQ

In 1979 the legend caused a mass panic in Japan.
How do you escape Kuchisake-onna?

Did the 1979 panic really happen?
Yes. Starting in Gifu prefecture in spring 1979, the rumour triggered school escorts and parent patrols, and police stepped up rounds. It's the first Japanese urban legend with a documented public impact.
