Mr. Osomatsu Season 4: Production Confirmed, New PV Out!


The production of the fourth season of the TV anime “Mr. Osomatsu” has been confirmed. Along with this announcement, the key visual and promotional video (PV) for the fourth season have been released, and comments from the six voice actors celebrating the fourth season have also arrived. Additionally, a special live radio program, “Six Kids Radio,” commemorating the fourth season’s production decision, has been scheduled.

The TV anime “Mr. Osomatsu” is based on Fujio Akatsuka’s classic gag manga “Osomatsu-kun.” It depicts the main characters, the six brothers, as adults who have turned into lazy, jobless ne’er-do-wells. The first season aired from October 2015 to March 2016, the second season from October 2017 to March 2018, and the movie “Mr. Osomatsu the Movie” was released on March 15, 2019. The third TV series season was broadcast from October 2020 to March 2021 on TV Tokyo and other channels. Additionally, to commemorate the sixth anniversary of “Mr. Osomatsu,” two special movies were released nationwide: “Mr. Osomatsu: Hipipo Tribe and the Shining Fruit” in July 2022 and “Mr. Osomatsu: Soul’s Takoyaki Party and the Legendary Sleepover” in July last year.

The visual released along with the fourth season’s announcement is an intriguing piece drawn by Eiji Abiko, who has been in charge of character design since the third season. The visual does not depict the six brothers but instead shows their usual hoodies neatly folded. This peculiar situation raises anticipation about what the fourth season of “Mr. Osomatsu” will entail.

Additionally, a PV celebrating the fourth season’s production has been released, where the six brothers express various emotions such as anticipation, joy, and even resentment while repeatedly shouting “Season 4!” Be sure to pay attention to the voices of the six brothers.

Jun Fukuyama, who voices Ichimatsu, humorously remarked, “You’re planning to do weird things again in Season 4, aren’t you?” and Miyu Irino, who voices Todomatsu, added a thought-provoking comment, “It feels like it’s going to be something completely different from what we’ve had before.” These comments reflect the unique and playful spirit of “Mr. Osomatsu” and build anticipation for the upcoming fourth season.

Full Cast Comments

Takashi Sakurai (Voice of Osomatsu)

“Mr. Osomatsu” Season 4 is happening.

It’s a bit ticklish to divide this series by “seasons,” but I’m very happy to keep adding more, so I want to do my best for the next one.

It seems like there are some plans in the works. Stay tuned.

Yuichi Nakamura (Voice of Karamatsu)

Season 4… Season 4!? I can’t believe it’s Season 4.

Are we planning to go up to Season 6 with this enthusiasm?

I’m not sure, but in any case, we’ll be causing a ruckus with all our might.

What kind of commotion awaits us this time… Stay tuned!!!

Hiroshi Kamiya (Voice of Choromatsu)

It seems “Mr. Osomatsu” is getting a fourth season. “What happens twice will happen thrice” is not usually a positive saying, but what happens after the third time…?

Maybe it will become an annual tradition? We might even start calling it essential.

I hope this once-in-a-lifetime celebration becomes a regular event…

We are going all out for “Mr. Osomatsu” Season 4.

Jun Fukuyama (Voice of Ichimatsu)

“Mr. Osomatsu” is finally getting a fourth season.

I initially declared that I wanted to go up to Season 6, and it might not be just a dream anymore.

But, you’re planning to do weird things again in Season 4, right?

If that’s the case, I don’t know what the future holds.

It’s a matter of life or death. I will approach it with caution. Yes.

Daisuke Ono (Voice of Jyushimatsu)

Season 4 is confirmed! A huge thank you with a grand slam goodbye! Let’s go, muscle muscle!

Hustle hustle! Boweh! Bowehver!

Well, now that it’s Season 4, I can’t think of any witty comments!

Just watch it, you’ll see! Let’s go! 1, 2, 3, 4 Seasons!

Miyu Irino (Voice of Todomatsu)

Season 4! Finally! Yay! However, it seems like it will be something completely different from what we’ve had before.

According to rumors. But really, it’s just at the rumor level, so I don’t know for sure.

Anyway, I’m looking forward to it. Enjoy the inappropriate “Mr. Osomatsu” that defies the times.

Maybe it will turn out to be a super proper “Mr. Osomatsu.”

Well. Whatever it is! It’s a festival, a festival.
