was a monthly manga magazine published by Gakudà Âsha between December 1947 and October 1955. The magazine was important in forming and promoting shà Ânen manga in post-war Japan.
The magazine was first published on 20 December 1947.
The magazine under the editorship of Kenichi Katà  motivated its readers in its unique "readers section" to send in their own comics to the magazine for competitions. Many new artists emerged due to this; for example Yoshihiro Tatsumi and Hideko Mizuno at a young age sent in manga to competitions of the magazine. Young artists published in the magazine were often contacted by other publishers for commissions. Shotaro Ishinomori, Fujiko Fujio, Jirà  Tsunoda and Leiji Matsumoto started their professional careers in the magazine. Tezuka founded his magazine COM in 1967 with the intention to give space for new manga artists to experiment, like Manga Shà Ânen had been during its existence.
The magazine managed to capture the new graphic developments of story manga, as it was popular in the Osaka-based akahon market and gained a big readership. Kenichi Katà  had previously been the editor of the popular boys magazine Shà Ânen Club at Kodansha and had good connections to some of the most popular artists at the time. Kimba the White Lion by Osamu Tezuka was the most popular series from the magazine.
Among the series featured in the magazine were:
