Shueisha

Shueisha Inc. (Japanese: 株式会社集英社, Hepburn: "Kabushiki-gaisha Shūeisha") is a Japanese company headquartered in Chiyoda, Tokyo, Japan. The company was established in 1925 as the entertainment-related publishing division of Japanese publisher Shogakukan. The following year, Shueisha became a separate, independent company.
Manga magazines published by Shueisha include the "Jump" magazine line, which includes shonen magazines "Weekly Shōnen Jump", "Jump SQ", and "V Jump", and seinen magazines "Weekly Young Jump", "Grand Jump" and "Ultra Jump". They also publish other magazines, including "Non-no". Shueisha, along with Shogakukan, owns Viz Media, which publishes manga from all three companies in North America.
