The Heisei era Osomatsu-kun is the 2nd TV anime adaptation of Fujio Akatsuka's gag manga, and it originally ran for 88 episodes on Fuji TV from 1988 - 1989. The Heisei era Osomatsu-kun is directed by Akira Shigino and features animation from Studio Pierrot.
The re-broadcast of Osomatsu-kun begins on Chiba TV on November 17, 2015, at 5:30 PM JST, and will it continue every Tuesday at the same time on a weekly schedule thereafter. Please note: Although the series originally ran for 88 episodes, only 86 episodes are listed for the re-broadcast.
