Ju-On

Ju-On (呪怨, Juon; lit. 'Curse Grudge', also known as The Grudge) is a Japanese horror franchise created by Takashi Shimizu. The franchise began in 1998 with the release of the short films Katasumi and 4444444444. Shimizu attended the Film School of Tokyo, where he studied under Kiyoshi Kurosawa. Kurosawa helped Shimizu shepherd the Ju-On projects to fruition. The Ju-On films generally revolve around a curse created in a house in Nerima, Tokyo, when Takeo Saeki, convinced that his wife, Kayako, is having an affair with another man, murders her, their son, Toshio, and Toshio's pet cat in a jealous fit of rage. According to Ju-On, when a person dies with a deep and powerful rage, a curse is born. The curse gathers in the place where that person has died or which they frequented, and repeats itself there. The spirits of the deceased haunt the location, potentially killing anyone who encounters the curse by any means, such as entering a cursed house or being in contact with somebody who was already cursed after entering it. The curse's manifestation is mainly death, where the victims' bodies may or may not disappear. The following deaths may create more curses and spread them to other locations. The franchise consists of thirteen films, including four American-produced films and one streaming television series, alongside various additional media and merchandise products.
