Osomatsu-kun (1988)

Osomatsu-san (おそ松さん) is the 2015-2018 re-imagining of Osomatsu-kun, in time for Fujio Akatsuka's 80th birthday, by Studio Pierrot and the Osomatsu-san Production Committee. It is distinguished from its predecessors with its honorific -san instead of -kun (the former is a general honorific whereas the latter is normally used for young boys).

Crunchyroll picked the series up for online streaming worldwide except for Asia, streaming it under the English localized title of Mr. Osomatsu. It began broadcast on TV Tokyo on October 5, 2015 and completed its first season on March 29, 2016.

On April 6, 2017, a sequel series was announced at a theatrical screening event for selected skits of the show, and started broadcast October 2, 2017, wrapping up March 26, 2018. Both seasons are 25 episodes long, although controversies with the first season's first episode resulted in it being banned.

The anime has spawned a large media-mix directive; a parallel work manga, several collaborations, merchandise, and specific tie-ins such as drama CDs and light novels.


After Pierrot's adaptation of Shirokuma Cafe wrapped up, the screenwriter Toru Hosokawa expressed interest in doing another project with the same voice cast and had wished to helm an adaptation of Fujio Akatsuka's The Genius Bakabon next.

However, this would not be his next project, as the request from Fujio Pro was for a new Osomatsu-kun anime for the modern decade. Hosokawa quickly became resistant to the idea of producing a late-night gag anime for mature audiences that involved child characters (and this too was complicated by how there were no available daytime slots for -kun). Because of this, he proposed to Pierrot that the title be changed to "Osomatsu-san" and the characters aged up to be adults. Furthermore, in tweaking that setting, the sextuplets could also be made more individual and take back their protagonist status from Iyami.

In the pitch he put together for "Osomatsu-san" (with plans to write and direct), it was more of a direct sequel to -kun and took place 20 years later; the sextuplets would be 30-year old salarymen and dealing with adult issues, as well as their supporting cast still being involved in antics.

Hosokawa had written the settings for a 24-episode series and had finished 8 of the scripts when disagreements with higher-ups happened over his concept and he left the project. As a result, Hosokawa's version of "Osomatsu-san" was thrown out, but he was asked permission for the next showrunner in mind to use the "-san" title and idea of adult sextuplets.

A modified pitch, now helmed by Yoichi Fujita as director and Shu Matsubara as head writer, was subsequently approved by Pierrot and production committee parties, although more elements of the characters changed as the production went on; the sextuplets initially all appeared identical as they had when younger, but were given such distinguishing features and expressions to tell them apart (along with their modified personalities). In this version, the sextuplets' ages were set as a vague "20s" and they would be jobless NEETs along with being desperate virgins. The loose concepts of Hosokawa's episodes 1 and 2 were repurposed and rewritten by Matsubara into the first two episodes, while the other 6 scripts remained unused.

The series engages in a lot of meta-comedy and breaking of the fourth wall, having the characters know that they're fictional and acknowledging it on occasions. Much like the manga and previous incarnations, there are no permanent settings other than the brothers having to remain NEETs and virgins and to fail at their attempts at breaking out. Characters are often killed only to appear alive later, as with Akatsuka's original works.

The humor in the series is considerably more adult than the original -kun incarnation, and the sextuplets are back to being the protagonists while characters such as Iyami and Chibita are relegated to being the supporting cast.

Season 1 was initially considered to be 12 episodes in its earlier stages of development, but an extension to a second cour (13-25) was quickly decided with anticipation of the series' popularity. This second cour was withheld from being announced until a few episodes into the series' run, as assurance that the series would have more for the fans to look forward to. This pattern repeated with the second season as well.


Sealed episodes

On November 5, 2015, a month after the series' debut, the Osomatsu-san Production Committee announced that the first episode "Osomatsu-kun Returns" would be taken off streaming sites and withheld from release in the home video version, only citing "various circumstances". The episode is now considered a sealed work, a term for content that has been banned and taken out of circulation.

It is figured that the various parodies and crude content in the first episode may have caused the threat of legal action from other rightsholders, as there are strict policies about copyrights where parodies are technically not protected. Reruns and the home video releases now start at episode 2 instead.

This type of incident would repeat with the third episode, due to the parody of Anpanman in "Dekapanman" which prompted an official apology from TV Tokyo for the "shameful act" against the series. The skit was edited for reruns on satellite TV, and it was then decided to remove it from further broadcasts and streaming.

The home video version of the episode entirely lacks the "Dekapanman" skit, and instead has a post-episode live-action sequence titled "Real Matsu" that features a group of men going around Tokyo wearing masks of the sextuplets' faces.

The deletion of episode 1 and this other incident quickly caused the order of the series to be rethought, resulting in the re-arrangement of some skits and the creation of the recap episode. Two skits that were withheld from broadcast were later included on the first home video release and reruns as an "Episode 3.5", with a disclaimer beforehand telling viewers to mentally place it between episodes 4 and 5.

In Viz Media's streaming and releases, they have attempted to fix this anomaly with the episode ordering by labeling Episode 2 as "Episode 1", while 3.5 becomes "Episode 3" (although the disclaimer still remains).

Hosokawa's confession

Prior to July 4, 2018, the circumstances that involved the change in direction for the "Osomatsu-san" project were never really detailed, along with the specifics of who was involved.

However, in the lead-up to the airing of Pierrot+'s Late Night! The Genius Bakabon, Toru Hosokawa shared the anecdote of how he had waited to write and direct such a series for years, and had detailed his history with the "Osomatsu-san" project.

This generated some tweet controversy among fans of -san, as they took Hosokawa's words as bashing the version that made it to air and drawing unnecessary comparisons between -san and Bakabon. Though Hosokawa apologized and attempted to clear up such misunderstandings, the tweets were later deleted.

Lyrics- Yoshinori Sugimoto/ Composers- Tatsuro Araki, Yoshinori Sugimoto/ Singers- AOP

Used for the second cour from 13 to 25. The "Batankyu" (バタンキュー) in the title was chosen as a callback to the Showa era, as it is a sound effect used for someone collapsing from exhaustion.

Season 2

"Approaching Cautiously" (君氏危うくも近うよれ Kunshi Ayauku mo Chikau Yore)

Lyrics- Asaki/ Composer- Mafumafu /Singers- AOP

Used for episodes 1 to 13. In episode 13, the ending image is changed to have Todomatsu removed as part of the episode's gag.

"Illusionary Wink" (まぼろしウインク Maboroshi Winku)

Season 1

"SIX SAME FACES ~Tonight's the Best!~" (SIX SAME FACES~今夜は最高!!!!!!~)

Lyrics, Composition- TECHNOBOYS PULCRAFT GREEN FUND/Singers- Kenichi Suzumura, Takahiro Sakurai, Yuuichi Nakamura, Hiroshi Kamiya, Jun Fukuyama, Daisuke Ono, and Miyu Irino

The ending theme used for the first cour. Alternative versions are used depending on the episode, with a"Type A" and "Type B" version used for each brother; the select sextuplet narrates about themselves to the viewer, who is part of a group of sextuplet sisters in the song.

The choral parts are sung by Kenichi Suzumura as Iyami, ranting about the brothers' popularity even though they look the same, and how he is ignored.

"SIX SHAME FACES ~Tonight's also the Best!~" (SIX SHAME FACES~今夜も最高!!!!!!~)

Lyrics, Composition- TECHNOBOYS PULCRAFT GREEN FUND/Singers- Aya Endo, Takahiro Sakurai, Yuuichi Nakamura, Hiroshi Kamiya, Jun Fukuyama, Daisuke Ono, and Miyu Irino

This ending theme features each brother trying to flirt with the viewer, who turns out to be Totoko rejecting them and refusing to get with them as they don't fit her dream of "hot guys". The "Type M" versions have the lyrics of the average Matsunos, while the "Type F" lyrics relate to their F6 fantasy selves who Totoko feels she's unworthy of.

This theme is used from episodes 13 to 24, with episode 25 having a different special ending:

"SIX SAME FACES ~Tonight's the Best!~ (TYPE: FINAL)" (SIX SAME FACES~今夜も最高!!!!!!!!!!!!!!~ -type FINAL-)

Lyrics, Composition- TECHNOBOYS PULCRAFT GREEN FUND/Singers- The Osomatsu-san All Stars (Takahiro Sakurai, Yuuichi Nakamura, Hiroshi Kamiya, Daisuke Ono, Miyu Irino, Kenichi Suzumura, Aya Endo, Sachi Kokuryu, Momoko Saito, Kujira, Kazuhiko Inoue, Yōji Ueda, Nobuo Tobita)

The ending theme for episode 25. It is mostly the first ending, with some lyrics of the second mashed up into it, and featuring all the voice cast singing and speaking as their characters.

Lyrics- Shu Matsubara/ Composition- Yukari Hashimoto/ Singer- Kenichi Suzumura

A special summer-themed ending for episode 5, loosely referencing the original Osomatsu-kun Ondo.

"Adults÷6×Kids×6" (大人÷6×子供×6)

Lyrics- /Composition- /Singers- The Osomatsu-sans with Matsuno Family Sextuplets (Takahiro Sakurai, Yuuichi Nakamura, Hiroshi Kamiya, Jun Fukuyama, Daisuke Ono, Miyu Irino)

Overseas Broadcast and Adaptations

South Korea

Starting May 28, 2016, a Korean dub was broadcast on the channels AniBox, Anione, and CHAMP TV, under the title of 오소마츠 6쌍둥이 (The Osomatsu Sextuplets). Unlike the dub of the 1988 series, the characters' names are retained.

There is still some editing and censorship in the dub, to conform to Korean TV broadcast standards as well as to remove any content deemed to be too nationalistic. A Korean-subtitled version of the original series was also aired.


The licensor Mighty Media announced its acquisition of the series on December 22, 2016, and started to roll out merchandise for the series in January 2017.

A television broadcast is planned.

Light Novels:

Osomatsu-san the Novel: Beforematsu and Aftermatsu

(小説おそ松さん 前松, 小説おそ松さん 後松)

Two light novels meant to showcase extra adventures of the brothers happening at points before and after the anime run, although with the intentional lack of continuity in such a gag show, both can stand well enough on their own and should not be considered prequels nor sequels. Both are written by the novelist Sora Ishihara, and contain illustrations by Naoyuki Asano.

The first novel focuses more on the older trio (Osomatsu, Karamatsu, and Ichimatsu) while the second focuses more on the younger trio (Ichimatsu, Jyushimatsu, Todomatsu). Each have 10 chapters.

Beforematsu was released by JUMP J BOOKS on July 29, 2016, with Aftermatsu later following on November 29, 2016.

Osomatsu-san Extra Edition

(おそ松さん ~番外編~)

An extra light novel marketed along with Beforematsu and Aftermatsu, and written by Ogura Oshima. It contains four short stories of the brothers' adventures. It was released through Shueisha's Future Paperback on July 22, 2016.

VS. Kochikame


A crossover light novel produced as part of the collaboration for Kochikame's 40th anniversary and final manga serialization. It is written by Sora Ishihara, and features the sextuplets meeting the protagonist Kankichi Ryotsu.

It was released by JUMP J BOOKS on September 17, 2016.

The Calming Detective Osomatsu Returns


A short story by the author Otsu Ichi in the May 2016 issue of The Da Vinci. It is an alternate retelling of the Calming Detective skit, focusing on Totoko recounting the events of Karamatsu's death. The twist ending of the killer is ultimately very different.

The story has not been reprinted since its original publication.


From the House of the Six Matsuno Brothers!


An official fanbook published by PASH in April 30, 2016, to commemorate the series. It features interviews, setting art, and information on the characters and episodes.

Sextuplet Guides

Margaret Comics released six individual guides to each brother, chronicling their roles in the anime and including recaps of information and images on them.

These can be seen as scaled-down versions of the PASH fanbook in content.

The Oso-Das: Osomatsu-san Discussion Guide


A book supervised by the Osomatsu-san Production Committee, only crediting the anonymous "Sheeh-eisha Institute" as the editor.

It discusses theories on the series, and purports to give answers to "67 Mysteries" of it, outlining questions raised in episodes and providing analysis and possibilities.


Osomatsu-san Hesokuri Wars: Battle of the NEET


A smartphone app released by Avex Pictures and DLE, for iOS and Android. The player can control various versions of the brothers, who battle against other characters to defend their house.



A puzzle app for smartphones distributed by D-Techno. The player can unlock various super-deformed versions of the brothers through playing the game, and level them up to unlock further bonuses.

Osomatsu-san: Hachamecha Party!

Browser Games: Pleasing Totoko-chan/Osomatsu-san's Black Factory/Quiz Battle


Three games available through Yahoo, and produced by DLE. In Pleasing Totoko-chan, the sextuplets must give Totoko the proper gift or risk a severe beating.

Osomatsu-san's Black Factory involves the sextuplets having to construct items at the factory, as they did in "Let's Get a Job". The Quiz Battle game involves the player having to answer trivia questions about the show correctly.

Osomatsu-san's NEET Sugoroku Cross-Trip


AKA "Tabimatsu" (from 旅 tabi, trip/journey). In this app by GOODROID and Avex Pictures, the sextuplets go traveling throughout Japan to collect all the money they can in hopes of achieving specific goals (which wind up backfiring on them).

The game includes many skits at each location, as well as a feature where the user can buy furniture and items for a room to attract different versions of the sextuplets (who will steal money if left to idle too long).

Osomatsu-san Matsuri

(おそ松さん 松まつり!)

A selection of mini-games released by Bandai Namco for the Nintendo 3DS on December 22, 2016.

A visual novel released by Otomate for the Playstation Vita on March 23, 2017. The player acts as a job advisor for the sextuplets, and must rehabilitate the NEETs to become working men. Of course, this will always be futile, considering the characters involved.

Theatrical Screening Event 2017: "Spring Nationwide Invitational Screening Festival"

(おそ松さん 春の全国大センバツ上映祭」)

On April 6, 2017, a nationwide screening event launched at movie theaters. Six rooms were set aside in each for each sextuplet, and would play selected shorts of the anime related to them.

A new "Bathhouse Quiz short" appeared as extra content, being a rejected skit from the Christmas episode, along with a short that announced the sequel. In the short, the Matsunos are called by Osomatsu to the fishing hole for the surprise announcement but are left in suspense. Suddenly, the "spiritually unavailable" (due to absence of the overseas Miyu Irino) Todomatsu temporarily rouses to announce the greenlighting of the sequel, and then goes back to his unconscious state.

An announcement trailer was also broadcast after the event, confirming the next run.
