May 24 brought a special celebration for fans of Osomatsu-san as the franchise marked the birthday of its famous sextuplets with an unprecedented cross-media collaboration.

The TV anime, the film "Osomatsu-san: Humanity Degradation Plan!!!?" (releasing June 12), and the stage production "Osomatsu-san on STAGE ~SIX MEN'S SHOW TIME~ 2nd SEASON 2" (also launching June 12) all participated in the birthday tribute. A collaborative visual was unveiled featuring an impressive lineup: the live-action film's cast—Seiya Suezawa, Yoshinori Syoumon, Akiyoshi Sano, Takeshi Kojima, Richardo Keita Kusama, and Takuya Nishimura—alongside stage performers Tomoya Nakanishi, Hiroyuki Ohno, Masahiro Sugisaki, Junpei Mitsui, Aokito Nakamura, and Kazuki Homma, plus the animated characters themselves. All 18 representatives struck the series' signature "shee" pose in what organizers called a "luxurious" visual.

The collaboration extended beyond the static image. On May 24 exclusively, the official X accounts for the anime, film, and stage versions were taken over by the sextuplets themselves in a special commemorative campaign, giving followers a peek at how each adaptation was portraying the characters.

The timing of these releases creates an exciting convergence for the franchise. The film adaptation brings the beloved characters to live action while maintaining the comedy that defines the series, while the stage production continues with its second season, keeping theatrical fans engaged. The anime remains a constant presence across the franchise's various iterations.

Osomatsu-san has proven remarkably adaptable across different media formats since its original manga debut. This birthday celebration demonstrates the franchise's sustained popularity and the dedication of production teams across anime, film, and theater to honor the characters' significance to fans. The coordinated effort shows how multi-platform properties can create unified fan moments even while maintaining distinct interpretations of the source material.
