Seinen Manga

Seinen manga (青年漫画?) is a subset of manga that is generally targeted at a 18–30 year old male audience, but the audience can be older with some manga aimed at businessmen well into their 40s. In Japanese, the word Seinen means "young man" or "young men" and is not suggestive of sexual matters. (The female equivalent to seinen manga is josei manga.)

It has a wide variety of art styles and more variation in subject matter, ranging from the avant-garde to the mundane and to the pornographic. Because of the emphasis on storyline and character development instead of action, some seinen series are often confused with shōjo, or girls' manga. This is especially true of seinen comedy series such as Chobits, and Chi's Sweet Home, or seinen drama such as Twin Spica. Other examples of seinen manga include: Akira, Monster, Gantz, 20th Century Boys, Berserk, Battle Royale, Blame!, Vagabond, Ghost in the Shell, Hellsing, Black Lagoon, Ikigami, Elfen Lied, Another, Battle Angel Alita, Zetman and Drifters. Rumiko Takahashi's Maison Ikkoku is sometimes classified as seinen, although this is disputed by some fans.

A common way to tell if a manga is seinen is by looking at whether or not furigana is used over the original kanji text: if there are furigana on all kanji, the title is generally aimed at a younger audience. The title of the magazine it was published in is also an important indicator. Usually Japanese manga magazines with the word "young" in the title (Weekly Young Jump for instance) are seinen. Other popular seinen manga magazines include Ultra Jump, Afternoon, and Big Comic.
