Jiraiya

His name came from old Japanese story(Jiraiya Goketsu Monogatari). This story was published over 30 years! The origin of this Jiraiya was actually named (Garaiya, meaning I came) in an old story in China called (Kaishi). Even name, Jirayia has a few different ways to write in Kanji.
This story is now played in (Kabuki). The way Jiraiya looks in Naruto is similar to what he looks like in the Kabuki play. They way he talks is also from Kabuki.
