Originally based on didactic Buddhist tales, kaidan often involve elements of
karma, and especially ghostly vengeance for misdeeds. Japanese
vengeful ghosts (
Onryō) are far more powerful after death than they were in life, and are often people who were particularly powerless in life, such as women and servants. This vengeance is usually specifically targeted against the tormentor, but can sometimes be a general hatred toward all living humans. This untargeted wrath can be seen in
Furisode, a story in Hearn's book
In Ghostly Japan about a cursed
kimono that kills everyone who wears it. This motif is repeated in the film
Ring with a videotape that kills all who watch it, and the film franchise
Ju-on with a house that kills all who enter it. Kaidan also frequently involve water as a ghostly element. In Japanese religion, water is a pathway to the
underworld as can be seen in the festival of
Obon. ==See also==
