Kuchisake onna (Japanese Slit-Mouthed Woman)

Kuchisake onna is a well-known creature in Japanese urban legends, known for her distinctive facial disfigurement and regular behavior. Stories about her became especially common in the late 1970s, sparking fear throughout Japan.

People usually claim to see her on empty roads or near schools, where she starts a particular conversation with those she meets. This encounter often ends violently, which is why she is considered one of the most frightening figures in modern Asian folklore.

Description

Kuchisake onna is a vengeful spirit, known in Japanese folklore as an onryō, whose anger comes from how she died. She is mostly known for appearing in modern cities and often targets children and young adults. Unlike traditional ghosts that stay in one haunted house, she moves along certain outdoor paths.

She is known for a ritual-like encounter. She hides her face as she approaches and asks people if they think she is pretty. How someone answers decides how badly she will attack. People believe there is no safe answer, as both yes and no can lead to harm.

Her story connects old Japanese tales about yokai with today’s internet horror stories, known as creepypasta. She reflects modern fears about strangers and safety in cities.

Etymology

The name “Kuchisake onna” comes directly from Japanese words. “Kuchi” means “mouth,” “sake” comes from a word meaning “to be torn” or “split,” and “onna” means “woman.”

Together, the name means “Slit-Mouthed Woman,” describing her main physical feature. In the Edo period, it referred to different scary women with large mouths. Still, today it specifically means the urban legend about a woman whose mouth was cut from ear to ear.

How to Pronounce “Kuchisake onna” in English

In English, you say her name as koo-chee-sah-keh ohn-nah. “Ku” sounds like the “oo” in “boot,” “chi” like in “cheese,” “sa” with a short “ah” as in “father,” and “ke” like the “e” in “get.” “Onna” uses a short “o” as in “on,” followed by “nah.”

Appearance

Kuchisake onna looks like a young woman with long, straight black hair that sometimes covers her face. Today, people often describe her wearing a long tan or beige trench coat. Since she appears in cities, she usually wears a surgical mask, which is common in Japan, so she can blend in until she picks someone to approach.

Under her mask, her face is badly scarred. Her mouth is cut from ear to ear, making a wide, uneven grin that shows her teeth and muscles. Some stories say her eyes look wild or very wide. She is almost always carrying something sharp, such as large scissors, a kitchen knife, or a straight razor.

Powers & Weaknesses

Powers

Kuchisake onna has abilities far beyond what people can do. Her most famous power is her incredible speed—stories say she can run 100 meters in just three to six seconds, so no one can outrun her. She can also suddenly appear in front of someone, no matter which way they try to escape.

As an onryō, she can appear and disappear whenever she wants, vanishing after her ritual is over. She is also extremely strong, especially in her hands, so she can hold victims still while using her blades.

Her main weapon, the scissors, is said to be so sharp that they can cut through flesh and bone instantly, leaving scars like her own.

Weaknesses

Even though she is dangerous, Kuchisake onna follows certain rules and has some weaknesses. One main weakness is her love for a hard amber candy called bekkoame. If someone gives her this candy, she gets distracted by eating or looking at it, giving the person a chance to escape.

She is also scared of the word “pomade.” Many stories say that if you say “pomade” three times or write it on your hand and show it to her, she will back away in fear or disgust.

She can also be temporarily stopped by confusing answers. If someone tells her, “You look average” or “So-so,” she gets lost in thought, which gives the person enough time to get away.

Myths, Legends & Stories

The story of Kuchisake onna is special because it has both old and new parts. Her modern version dates to the late 1900s, but the idea of a slit-mouthed woman dates back to stories from the Edo period (1603–1867).

The Jealous Samurai

The most popular origin story says she was once a beautiful woman who lived long ago. She was married to or involved with a powerful samurai. She was very vain and often tried to get attention from other men.

When her husband found out she was unfaithful, he became extremely jealous and angry. He attacked her with a sword, cutting her mouth from ear to ear to destroy her beauty.

As he did this, he supposedly said, “Who will think you are beautiful now?” After she died from her injuries, her spirit came back as a vengeful ghost, wanting to make others feel the pain she suffered.

The 1979 Panic

In late 1978 and through 1979, the legend shifted from a mere ghost story to a genuine social scare. It started in Gifu Prefecture, where people said an old woman with a slit mouth was chasing children.

By spring 1979, the story had spread all over Japan. The tale grew to include the surgical mask and trench coat, in keeping with the fashion of the time.

The panic got so bad that schools closed and police started patrolling more often. In some places, children had to walk home in big groups with teachers or parents. This time set the pattern for the legend: she walks up to a child and asks, “Am I beautiful?” (Watashi kirei?).

If the child says “No,” she kills them with her scissors. If the child says “Yes,” she takes off her mask to show her scars and asks, “Even now?” (Kore demo?). If the answer is “No,” she kills them; if it’s “Yes,” she cuts their mouth to look like hers.

The Failed Surgery

Another version of her story, often told in recent years, says she was hurt during a failed medical procedure. In this version, she was having plastic surgery. The surgeon used a lot of pomade in his hair during the operation.

The strong smell made the woman move or caused the surgeon to slip, which led to her face being accidentally and permanently scarred. This story explains why she reacts so strongly to the word “pomade.”

The Three Sisters

In some local stories, Kuchisake onna is actually one of three sisters. In this version, all three sisters had plastic surgery at the same time.

The first sister’s surgery failed, leaving her with a slit mouth. The second sister died during the operation. The third sister lost her mind from grief and seeing what happened to her siblings.

In this story, the Kuchisake onna people meet is the oldest sister, seeking new family members or seeking revenge on doctors.

The South Korean Migration

In the early 2000s, the legend spread to South Korea, where she is known as “Kkang-kkang-i” or simply the Red Mask woman.

In the South Korean version, she usually wears a red mask instead of a white one. These stories also say she might ask about blood types or be linked to certain red clothes. This shows how the legend adapts to different cultures while retaining its main ideas.

Symbolism

Kuchisake onna is a strong symbol of the fear of strangers that is common in crowded cities.

She stands for the fear of people who seem normal but are hiding something dangerous or strange. The surgical mask is important because it shows how Japanese culture values hiding things and keeping the peace. Still, she twists this by hiding something terrible under a polite look.

She also shows how beauty can be fragile and how vanity and jealousy can be harmful. Her appearances near schools reflect parents’ worries about keeping their children safe when they leave home for school.

Can Kuchisake onna Be Defeated?

Unlike many Western monsters that can be killed with weapons, Kuchisake onna cannot be truly defeated because she is a spirit created from shared pain and anger. She does not have a body that can be destroyed. Instead, people protect themselves from her using tricks and traditional protective items.

People who think they might meet her often carry bekkoame (hard amber candy) or gold-colored things, since some believe spirits are distracted by gold. Another way to stay safe is to use strong-smelling hair products, which are said to keep her away because of the surgery story.

Some stories say that if you write the kanji for “dog” on your palm and lick it before she comes, you will be safe, since dogs are seen as enemies of evil spirits in Japanese tradition.

In the end, the best way to escape her is to confuse or distract her long enough to get into a safe, brightly lit place or a crowd. She stays away from groups where many people could see who she really is.
