There was a Woman named 'Kuchisake Onna'
Her name means 'Woman with a split mouth'. If you are going somewhere by yourself during late night, she might jump in front of you and You can't run away from her because she can teleport herself in front of you.
The story goes that Kuchisake-Onna was a woman who had been badly mutilated by her husband (he sliced her mouth open on both sides) after cheating on him. Kuchisake-Onna died from the attack, but soon returned from the grave to wander the city streets dressed in a surgical mask asking one simple question-
"Am I pretty?"
If you answer 'no' she will cut off your head with a big pair of scissors, If you answer 'yes' then she will take off her mask, Revealing that her mouth is slit from ear to ear.
Then she will ask again, "How about now?" If you say 'no' she will cut you into halves, if you say yes, then she'll slit your mouth like hers.
To escape the Kuchisake-onna, you can answer her second question with "You're average" or "So-so", which will confuse her so that you can escape.
Alternatively, you can throw fruit or sweets at her feet, which she will pick up, thus giving the victim a chance to run.
One other option is to ask her if you are pretty: She will also get confused and leave.
And a fourth possibility is to say you have to meet up with your husband/your wife and she will excuse herself and leave.
