Osomatsu-kun (1988)

The first anime adaptation of Osomatsu-kun aired from February 5, 1966 to March 25, 1967 on NET (now TV Asahi). It was produced by Mainichi Broadcasting System, with Childrens Corner handling animation for the first 25 episodes and Studio Zero for the rest.

This marked Osomatsu-kun as the first Akatsuka work to be adapted into animated format.


The series more closely adapts from the Shonen Sunday manga that was running at the time in comparison to the second TV adaptation, however, there were some adjustments made to the adaptations of stories. Iyami and Chibita were written into earlier stories, taking the places of random guest characters, along with others like Hatabō being added into plots.

Most episodes were divided into two unrelated shorts, although there were cases where two-part stories would be featured. Some later episodes would also contain only one new short, opting to rebroadcast an earlier story along with it. Towards the end of the run, perhaps due to budget or other reasons in wrapping it up, some airing slots (including the final three) entirely consisted of rerun segments.

Fujio Akatsuka is said to have not liked the early episodes produced by Childrens Corner, due to the inexperienced animators that resulted in a lot of off-model moments. Studio Zero took control for the later half of the series, along with Akatsuka giving the proposal for "Chibita the Safe-Cracker" to be adapted as a two-parter. Besides the Osomatsu-kun manga serialized in the Shogakukan magazines, some chapters of the manga Kantaro (serialized in Shueisha's Shonen Book) were adapted and rewritten to be episodes about Chibita, as both characters were identical and Chibita was becoming popular. In some cases, the segments would wind up having the other -kun characters incorporated as well. The story of "Great Car Race of the Century", which appeared as an extra feature in Weekly Shonen Sunday, was also adapted into an episode ("The Grand Prix Annihilation Race").

After the series was rebroadcast on Tokyo Channel 12 (now TV Tokyo) in the early 1970s, the film masters went missing and were believed lost or destroyed. The reels to the series were found in a MBS Senrioka warehouse in 1990, and it has seen home video release on VHS and DVD since.

The sextuplets' actors were not consistent through the full series run, save for those of Osomatsu and Jyushimatsu (see "Trivia" for more).

Hatabo's actress was incorrectly believed to be Takako Sasuga due to the book "TV Anime Memories of 25 Years" claiming such, however the book was later found to have many unsourced claims or mistakes with credits. The character was never credited in the series, with the exception of episode 21.

  • The segments of "First-Class Car Race Jo~", "Chibita the Zookeeper", "Fighting Robot Rampage", "Dekapan Olympics", "I Do Not Need the Magic Lamp Anymore", "Keke, I'm a Detective!", "My Head's Shine is the Best in the World", "Go to Chibita's Jungle", and "Chibitaro Came from a Peach" were all originally chapters of the aforementioned Kantaro series, which either already had other Akatsuka characters guest-starring or were reworked to include them (such as in the Olympics skit and car race). There is little conflict with this, due to Kantaro having the same basic type of personality as well as loving oden and having other familiar characteristics.
  • The sextuplets' voices sometimes change over the run of the series, depending on the availability of the actresses for a given episode. Fuyumi Shiraishi is shown to have occasionally understudied for Karamatsu and in turn, Keiko Yamamoto and Mari Kitagawa had also covered the dual roles of Ichimatsu and Todomatsu.
    • In some early stages, Keiko Yamamoto was left absent from the credits while she was actually present, with the alias "Emiko Suzuki" appearing instead and attributed to Karamatsu (while she voiced both him and Choromatsu). Her usage of the alias came about due to already being cast for the lead of Fight! Osper and not being able to be credited as another lead role at the time[2]
