On May 30, it was officially announced that DA PUMP, the renowned Japanese dance and vocal group, will perform the opening theme for Season 4 of the anime Mr. Osomatsu (Osomatsu-san). The theme song, titled “Osomatsu-san no Bombashe!”, is a Japanese-language cover of a foreign track with lyrics written by longtime DA PUMP collaborator m.c.A·T. The group also revealed a new key visual of all six members dressed as the iconic character Iyami, striking his signature “Sheh!” pose alongside him.

A Dynamic Cover Blending Comedy and Pop

“Osomatsu-san no Bombashe!” is a reimagining of an overseas song with all-new Japanese lyrics. Lyricist m.c.A·T, who played a central role in DA PUMP’s early success, infuses the track with playful energy that reflects the comedic chaos of the series. The title’s use of “Sheh!” is a direct reference to the classic gag by Iyami, a recurring character in Mr. Osomatsu, further tying the song into the anime’s unique world.

Celebrating the Power of “6”

The number six is deeply symbolic in Mr. Osomatsu, which features six main characters, the mischievous Matsuno sextuplets. In a nod to this connection, a preview of the song will be released on June 6, reinforcing the show’s numerical motif.
