Mr Osomatsu Season 5: Few anime comedies lean into chaos quite like Mr Osomatsu (Osomatsu-san). The long-running gag series has survived cancellations, controversies, anniversary specials, and shifting formats—yet the Matsuno sextuplets remain as shamelessly lazy and unhinged as ever. After Season 4 wrapped in late 2025, fans are once again asking whether the brothers will return for another round of absurd adulthood.
Here’s where things stand, and why the franchise still feels far from finished.
Series Recap: How the Sextuplets Stayed Relevant
Studio Pierrot revived Fujio Akatsuka’s classic manga with a modern twist in 2015, reintroducing Osomatsu and his five identical brothers as unemployed adults rather than mischievous kids.
- Season 1 (2015–2016) delivered 25 episodes and instantly went viral for its fearless parody style. The now-infamous first episode was pulled for copyright violations, but the controversy only boosted attention.
- Season 2 (2017–2018) doubled down on meta humor, internet culture jokes, and exaggerated personality clashes.
- Season 3 (2020–2021) leaned into character-centric episodes while keeping the gag-heavy format intact.
- Season 4 (2025) shortened the episode count to 12 but sharpened its focus, blending anniversary energy with updated pop-culture satire.
Across four seasons, the anime has reached 87 episodes, all built around episodic sketches rather than long story arcs.
Why Mr Osomatsu Still Works
Osomatsu leads his identical brothers—Karamatsu, Choromatsu, Ichimatsu, Jyushimatsu, and Todomatsu—through aimless lives in modern Japan. As grown-up versions of the classic Osomatsu-kun kids, they chase get-rich-quick schemes, flirt disastrously, and clash in over-the-top scenarios. Supporting characters like greedy Iyami and food-obsessed Chibita add to the frenzy.
Season 1 sets the tone with parody-heavy sketches, though the debut episode faced a ban for infringing copyrights on famous anime and films. Creators pulled it from streams and home releases, replacing it with milder content. Later seasons ramp up the absurdity: brothers tackle job hunts, festivals, and supernatural mishaps. Fans cherish the rapid-fire jokes, character quirks—like Jyushimatsu’s boundless energy—and themes of family ties amid failure. The show rewards repeat viewings with hidden references, making it endlessly rewatchable for comedy enthusiasts.
Mr Osomatsu Season 5: Is It Happening?
As of January 2026, Mr Osomatsu Season 5 has not been officially announced. Season 4 concluded in October 2025, and Studio Pierrot has remained quiet about a follow-up. Historically, the series has taken multi-year breaks between seasons, often filling the gaps with films, specials, or collaborations.
Given that pattern, a 2027 return feels more realistic than anything sooner—assuming the production committee moves forward.
What Mr Osomatsu Season 5 Could Explore
If the anime returns, Osomatsu-san Season 5 is unlikely to change its formula—but that’s exactly the point.
Possible directions include:
- New parody targets tied to current anime trends and social media culture
- Workplace disasters and short-lived “career arcs” for the brothers
- Expanded focus on supporting characters like Iyami and Chibita
- Anniversary-style callbacks to classic Osomatsu-kun material
The series works best when it reacts to the moment, and that flexibility keeps Season 5 wide open creatively.
Ratings Snapshot
Despite its polarizing humor, the series has held steady popularity:
- IMDb: 7.5/10
- MyAnimeList: 6.17/10
The numbers reflect a loyal fanbase that understands exactly what kind of comedy it’s signing up for.
Cast for the New Season
One constant across every season has been the cast. The six-lead setup only works because each brother feels distinct, and the veteran voice actors bring sharp timing and improvisational energy. Any future season would almost certainly keep the full original cast intact, as their performances are inseparable from the show’s identity.
Where to Watch
All seasons of Mr Osomatsu are currently available on Crunchyroll, with both subtitled and dubbed options. Depending on the region, episodes may also stream on Prime Video, Tubi, or Peacock.
Final Thoughts
Mr Osomatsu doesn’t chase trends—it mocks them. That’s why the series keeps surviving long after similar gag shows fade out. While Season 5 hasn’t been confirmed yet, the franchise’s history suggests the Matsuno brothers are never truly gone—just temporarily unemployed. If and when the anime returns, it will likely do what it does best: say absolutely nothing meaningful, in the loudest way possible.
