Kaidan
Kaidan (怪談; sometimes transliterated kwaidan) is a Japanese word consisting of two kanji: 怪 (kai) meaning 'strange, mysterious, rare, or bewitching apparition' and 談 (dan) meaning 'talk' or 'recited narrative'. In its broadest sense, kaidan refers to any ghost story or horror story, but it has an old-fashioned ring to it that carries the connotation of Edo period Japanese folktales.
