The Japanese urban legend of Kuchisake-onna (the Slit-Mouth Woman) was believed to be very real in Japan’s Nagasaki Prefecture in 1979. In fact, reports back then were given such merit, the police stepped up patrols in the area and parents were warned not to let their children walk the streets unaccompanied by an adult.
Details of Kuchisake-onna’s legend vary from source to source but the prevailing tale is that she was the very beautiful wife of a Samurai warrior during Japan’s Heian Period (794-1185). When her husband discovered she had been unfaithful to him, he became outraged and slashed her mouth from ear to ear, leaving her horribly disfigured, wearing a permanent gaping and grotesque, evil smile. He then asked her “Who will think you’re beautiful now?”
