Imagine you’re walking down a quiet street in Japan at dusk. A lone woman approaches, her face obscured by a surgical mask—a common sight. She stops you and asks a seemingly innocent question in a soft voice: “Watashi, kirei?” (“Am I pretty?”).

This is no friendly inquiry. It is the beginning of a terrifying encounter with the Kuchisake-onna, the Slit-Mouthed Woman, one of Japan’s most infamous and enduring urban legends. Your answer will determine your fate, but be warned: in this deadly game, there is no right choice. This is the definitive story of the ghostly figure who sparked a nationwide panic, whose roots stretch back centuries, and who continues to haunt the global imagination.

The Legend: A Question with No Safe Answer

The classic tale of the Kuchisake-onna is a masterclass in psychological horror, a deadly conversational trap.

・If you answer “No” to her question, she immediately produces a weapon—often a pair of giant scissors, a knife, or a sickle—and kills you on the spot in a fit of rage.

・If you answer “Yes,” she leans in closer, her eyes glinting, and peels away her mask to reveal a grotesque, bloody gash where her mouth has been slit from ear to ear. “Kore demo kirei?” (“Am I still pretty now?”), she hisses.

Now, you are faced with an even more impossible choice. If you scream or falter and say “No,” she will cut you in half. If you manage to force out another “Yes,” your fate is just as grim. She will take her blade and slice your own mouth open, mutilating you to look just like her.

This core legend, which first terrorized Japan in the late 1970s, is just the beginning. The Kuchisake-onna is often described as a tall woman with long, black hair, wearing a trench coat to conceal her weapon. But as the story spread, she took on countless local forms: in some towns, she wore a blood-red coat; in others, a pristine white one. One disturbing variation from western Japan claimed she was one of three sisters—each with a different degree of mutilation—who would corner victims and demand they choose the prettiest among them, a fatal choice no matter the answer.

The 1979 Panic: When a Ghost Story Brought a Nation to its Knees

What began as a schoolyard rumor in Gifu Prefecture in late 1978 exploded into a genuine social panic by the spring of 1979. The legend of the Slit-Mouthed Woman spread like wildfire through the incredibly efficient network of Japanese schoolchildren, and soon, children from Hokkaido to Kyushu were terrified of walking home alone.

The hysteria was not just child’s play; it had real-world consequences.

・Police departments in Fukushima and Kanagawa were flooded with calls reporting “sightings,” prompting patrols to search for the phantom woman.

・Schools in multiple cities, fearing for their students’ safety, organized mandatory group walk-homes.

・Parent-teacher associations formed vigilante patrols to protect their neighborhoods.

The media fanned the flames with sensationalized articles, turning a ghost story into a tangible threat. The panic only subsided in August 1979, when summer vacation broke the chain of rumor transmission among schoolchildren. But by then, the Kuchisake-onna had cemented her place as Japan’s premier modern monster, a case study in how urban legends can spark real-world fear.

The Origins: From Ancient Folklore to Modern Anxiety

While the 1970s panic was a modern phenomenon, the motif of a slit-mouthed female specter has deep roots in Japanese folklore. Edo-period (1603-1868) texts contain chillingly similar tales of shape-shifting fox spirits and demonic courtesans who revealed grotesquely wide mouths to terrify unsuspecting men. These ancient stories provided the cultural DNA for the modern legend.

Folklorists suggest that the 1970s version of the Kuchisake-onna was a manifestation of contemporary anxieties. It was an era of rapid urbanization and the rise of juku (cram schools), which meant more children were out alone after dark in unfamiliar neighborhoods. The Kuchisake-onna became the ultimate embodiment of “stranger danger”—a terrifying warning to children in a changing society.

Over the years, numerous origin stories have emerged to explain who she was before becoming a vengeful spirit (onryō).

・The Samurai’s Wife: The most popular version, especially in the West, tells of a beautiful but unfaithful wife of a samurai. In a fit of jealous rage, her husband sliced her mouth open, screaming, “Who will think you’re beautiful now?”

・A Botched Surgery: A more modern take, gaining popularity in the 1990s, claims she was the victim of a cosmetic surgery gone horribly wrong, her face permanently disfigured by a surgeon’s slip of the scalpel.

・An Escaped Patient: The earliest rumors in Gifu described her not as a ghost, but as a deranged patient who had escaped from a nearby mental hospital, her smeared red lipstick mistaken for a bloody gash.

Surviving the Slit-Mouthed Woman: The Bizarre Rules of the Game

Is there any hope if you encounter the Kuchisake-onna? Over time, a fascinating and often contradictory set of “rules” and escape strategies developed within the folklore.

・The Pomade Trick: Shouting “Pomade, pomade, pomade!” is said to repel her, as one origin story claims her mutilator wore heavily scented hair gel.

・The Candy Ploy: Tossing her bekkō-ame (a type of hard candy) can distract her, as she will stop to greedily eat them, giving you a chance to flee.

・The Ambiguous Answer: Responding to her question with a non-committal answer like, “You look average,” or “So-so,” can confuse her long enough for you to escape.

・The Money Distraction: A particularly creative rumor from the 1970s claimed she was obsessed with the arcade game Space Invaders, so throwing a handful of 100-yen coins would cause her to stop and collect them.

These bizarre countermeasures are a testament to the legend’s grassroots nature, as communities creatively devised their own ways to fight back against the spectral threat.

An Enduring Icon of Global Horror

Decades after the panic of 1979, the Kuchisake-onna remains a dominant figure in Japanese horror and a global pop culture icon. She has starred in numerous films, most notably the 2007 J-horror hit Carved: The Slit-Mouthed Woman, and has been featured in manga, anime (from a cameo in Studio Ghibli’s Pom Poko to inspirations in Jujutsu Kaisen), and video games like Ghostwire: Tokyo and World of Horror.

The legend endures because it preys on a simple, universal fear: a seemingly normal encounter that suddenly turns deadly. The surgical mask, once a symbol of illness or politeness, becomes a veil for unimaginable horror. The Kuchisake-onna is a chilling reminder that behind the most ordinary façade, a monster could be waiting, ready to ask you that one terrible question.
