CoroCoro Comic

Gekkan CoroCoro Comic (月刊コロコロコミック) is a Japanese monthly manga magazine published by Shogakukan, starting on May 15, 1977 as a magazine for Doraemon. Its main target is elementary school aged boys, younger than the readers of shōnen manga. The name comes from a phenomime korokoro (ころころ) which means "rolling" and also represents something spherical, fat, or small, because children supposedly like such things. The magazine is A5-sized, about 6 cm (2¼ in) thick, and often more than 800 pages in length.

The magazine also has other side publications:
 * Bessatsu CoroCoro Comic (別冊コロコロコミック), a bi-monthly magazine that began in 1981.
 * CoroCoro Ichiban! (コロコロイチバン!), first published in 2005.
 * CoroCoro G (コロコロG) from 2010.
 * CoroCoro Aniki (コロコロアニキ), which began with an irregular publication date in 2014 until it became a quarterly publication in 2017, being released on March, June, September, and December.

Tie-ins
CoroCoro regularly promotes toys and video games related to their manga franchises, releasing stories and articles featuring them. Pokémon's big success in Japan owes to this in a way; the Game Boy game Pocket Monsters: Blue was sold exclusively through the magazine at first, which helped CoroCoro's sales as well. CoroCoro is also often a source of information about upcoming Pokémon games and movies. CoroCoro also had tie-ins with Capcom, including the Mega Man franchise in the 2000s.
