Seinen manga (青年漫画) is an editorial category of Japanese comics marketed toward young adult men.[1] In Japanese, the word seinen means "youth", but the term "seinen manga" is also used to describe the target audience of magazines like Weekly Manga Times and Weekly Manga Goraku, which write on topics of interest to male university students and workingmen. Seinen manga is distinguished from shōnen manga, which is for young boys, and seijin-muke manga (成人向け漫画), which are intended for adult audiences and often contain explicit content. Some seinen manga like xxxHolic share similarities with shōnen manga. Seinen manga can focus on action, politics, science fiction, fantasy, relationships, sports, or comedy. The female equivalent to seinen manga is josei manga.
A common way to tell if a manga is seinen is by looking at whether furigana is used over the original kanji text: if there is furigana on all kanji, the title is generally aimed at a younger audience. The title of the magazine in which it was published is also an important indicator. Usually, Japanese manga magazines with the word "young" in the title (Weekly Young Jump, for instance) are seinen. There are also mixed shōnen/seinen magazines such as Gangan Powered and Comp Ace. Other popular seinen manga magazines include Weekly Young Magazine, Weekly Young Sunday, Big Comic Spirits, Business Jump, Ultra Jump, and Afternoon.
