CoroCoro

CoroCoro Comic (コロコロコミック KoroKoro Komikku) is a Japanese monthly manga magazine published by Shogakukan, established on May 15, 1977. Its main demograph is geared torwards elementary school aged boys, younger than the readers of shōnen manga. Several of its properties, like Doraemon and the Pokémon series of games, have gone on to be cultural phenomena in Japan.

The name comes from the 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 each issue is 750 pages long. CoroCoro Comic is released monthly with new issues on the 15th of each month (or earlier if the 15th falls on a weekend).

Currently the magazine has three active sister magazines: Bessatsu CoroCoro, CoroCoro Ichiban! and CoroCoro Aniki. Bessetsu was published bi-monthly, while Ichiban and Aniki were published monthly (formerly bi-monthly) and quarterly respectively. While Bessatsu and Ichiban! are kodomo/shonen manga magazines just like CoroCoro Comic was, CoroCoro Aniki is a only seinen manga magazine in the lineup.

Anime

To celebrate it's 40th anniversary, the anime special were produced. Takeshi Gouda sings to celebrate it, but Doraemon shrinks them with Small Light. After some talk with Doraemon charaters, Doraemon sings at the same way as he did in the first cover of the CoroCoro Comic. This anime special features many animes such of Yo-kai Watch! and a new magazine cover.

Trivia

There is a parody of CoroCoro Comic in the Doraemon anime called GoroGoro (ゴロゴロ) Comic. Nobita owns many GoroGoro issues and they are usually read by him or Doraemon. GoroGoro issues are always just background props in the anime.
