Hanako-san or Toire no Hanako-san ("Hanako of the toilet") is a Japanese urban legend about the spirit of a young World War II era girl who haunts school bathrooms. She allegedly appears when one shouts her name. According to the legend, a person who goes to the third stall in the girls' bathroom on the third floor and knocks three times before asking, "Are you there, Hanako-san," will hear a voice answer, "I'm here." If the person chooses to enter the stall, there will be a small girl in a red skirt. Hanako-san is a popular and widespread urban legend, often played by school children as a rite of courage, or a method of hazing for new students, similar to the Bloody Mary urban legend in Western schools.
