Seinen manga (青年漫画) is an editorial category of Japanese comics marketed toward young adult men.
Seinen manga can focus on action, politics, science fiction, fantasy, relationships, sports, or comedy.
Then, in 1967, the first magazine aimed at seinen appeared: Weekly Manga Action, which scored big hits with Lupin III, Lone Wolf and Cub, and later Crayon Shin-chan.
Many Young Jump series have been adapted into anime or live-action TV programs, such as Elfen Lied, Gantz, Hen, Kirara, Liar Game, Oku-sama wa Joshi Kōsei, and Dragon Ball.
