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 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". 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".
