GeGeGe no Kitaro (ゲゲゲの鬼太郎, GeGeGe no Kitarō?) is a manga series created in 1959 by manga artist Shigeru Mizuki. It is best known for its popularization of the folklore creatures known as yōkai, a class of spirit-monster to which all of the main characters belong. It has been adapted for the screen several times, as anime, live-action, and video games.
It must be noted that the actual title of the original manga is Hakaba Kitarō (墓場鬼太郎, Hakaba Kitarō?), literally meaning "Graveyard Kitaro". "Ge Ge Ge..." only applies to the anime. However, the manga was later republished under the anime title. In January, 2008, the original manga was finally adapted into an anime, running in Fuji TV's Noitamina slot.
