Japanese horror is Japanese horror fiction in popular culture, noted for its unique thematic and conventional treatment of the horror genre in light of western treatments. Japanese horror tends to focus on psychological horror and tension building (suspense), particularly involving ghosts and poltergeists, while many contain themes of folk religion such as: possession, exorcism, shamanism, precognition, and yōkai.
The origins of Japanese horror can be traced to horror and ghost story classics of the Edo period and the Meiji period, which were known as kaidan. Elements of several of these popular folktales have been worked into the stories of modern films, especially in the traditional nature of the Japanese ghost.
Ghost stories have an even older history in Japanese literature, dating back to at least the Heian period (794–1185). Konjaku Monogatarishū written during that time featured a number of ghost stories from India, China and Japan. Kabuki and noh, forms of traditional Japanese theater, often depict horror tales of revenge and ghastly appearances, many of which have been used as source material for films.
Certain popular Japanese horror films are based on manga, including Tomie, Uzumaki, and Yogen.
