Kitarō

Kitarō (鬼太郎, Kitarō), also known as GeGeGe no Kitarō(ゲゲゲの鬼太郎), is a yōkai boy born in a cemetery

after the death of his parents. Aside from his mostly-decayed father, Medama-Oyaji, he is the last surviving member of the Ghost Tribe. He fights for peace between humans and yōkai, which generally involves protecting the former from the wiles of the latter.

His name comes from a pre-war era picture story showentitled Hakaba Kitarō, featuring a character with a similar backstory. Shigeru Mizuki gives credit to author Masami Itōfor inspiring the character of Kitarō.

His father is Medama-Oyaji, and his mother is Iwako.

His birth year is 1954 in the first anime adaptation, but his birth day is unknown (he claims it to be February 30th in the 1968 anime). His exact age is unclear in the 2007 anime, however he saved a boy from Mōryō and Shibito-tsuki 50 years ago with the unchanged appearance, and he and others have battled against a group of Western Yōkai on multiple occasions for several decades or more to protect Amami Tribe and other inhabitants on Kikaiga Island. In the live-action film series, he is 350 years old.
