Yotsuya Kai Dan (四谷怪談), the story of Oiwa and Tamiya Iemon, is a tale of betrayal, murder and ghostly revenge. Arguably the most famous Japanese ghost story of all time, it has been adapted for film over 30 times, and continues to be an influence on Japanese horror today. Written in 1825 by Tsuruya Nanboku IV as a kabuki play, the original title was Tōkaidō Yotsuya Kaidan (東海道四谷怪談). It is now generally shortened,and loosely translates as Ghost Story of Yotsuya.
