About Mr. Osomatsu 4th season

Meet Mr. Osomatsu 4th season (おそ松さん 第4期), a comedy, sci-fi and slice of life anime by PIERROT FILMS and Studio Pierrot (2025). Here is the premise in a nutshell. At its core: The sextuplets run amok for a fourth time! Now adults in their 20s, they are still unemployed, undertrained, and single…but there’s something lovable about Japan’s most famous sextuplets.

From there, as a new chaotic adventure begins, what’s next? New companions? New trouble? Perhaps a new side to the sextuplets? Let’s all laugh together with these brothers who are beyond any hope.

With comedy at the core, timing, character chemistry and running gags decide whether it lands. Narrator (Hiroshi Kamiya) and Jyushimatsu Matsuno (Daisuke Ono) are two of the characters you will meet early. If you count yourself among viewers who want something light between heavier series, put it on your list. With 13 episodes in total, there is enough room for the story to develop.
