To start off with the spooky and creepiness of the world let’s begin with an urban legend from Japan (because you know that it’s going to be scary if it’s coming from there let me tell you that right now). This urban legend stems from a school setting some twenty or more years ago during a wave of ghost stories and sightings. There are different versions of this ghost depending on the school as do most sightings go, but this is the version I have read up on.
This version is that a little girl’s ghost haunts the school bathrooms, opening and closing doors to scare people who enter alone and who knock on a stall and call her name. Many dread going to the bathroom alone in case they run into her. I mean, who would want to go to the bathroom knowing a ghost girl is there to scare you?
This legend is very similar to the legend of Kashima Reiko, who is a female ghost with no legs that resides in school bathrooms as well who calls out to you. There are various ways as to answer her.
Another one is a male ghost who goes by many names (Aoi Manto/Aka Manto and others) who lives in the last stall in the girls’ bathroom. He asks those who enter, “Which do you prefer, the red paper or the blue paper?” If the person answers red, he will kill them by slashing them on the back or neck repeatedly to make it look like the person was wearing a red cape. If the person picks blue, he will kill them by hanging them.
So in conclusion, be careful when going to the bathroom in a Japanese school, just in case you end up running into any of these “friendly” ghosts.
