In foreign countries "Dracula", "Werewolf" and "Frankenstein" are well-known to people through horror stories. The word ghost reminds Japanese people of characters such as Oiwa (upon whom the story "Yotsuya Kaidan"is based), Otsuyu (upon whom the story "Botan Doro" is based), and Okiku (upon whom the story "Sarayashiki"is based). They are characters who appear in these famous ghost stories. ● Yurei --- When people die with unfinished business, they appear as a ghost in human form. ● Yokai --- People and animals appear in other forms.
