Viz Media announced the English dub cast for the six Matsuno brothers from the Mr. Osomatsu anime at its Anime Weekend Atlanta panel on Saturday. The cast includes:

All the cast members except Mittleman are appearing at the panel for the announcement and an autograph session.

The Mr. Osomatsu television anime is inspired by Fujio Akatsuka 's original Osomatsu-kun manga and "high tension comedy" TV anime, which centered on the Matsuno household with six naughty and mischievous sons (who are sextuplets). All of the sextuplets, including the eldest Osomatsu, are all in love with the same girl, Totoko. The original Osomatsu-kun series followed the family when the sons were 10 years old. Mr. Osomatsu re-imagines the original manga and TV anime with the sextuplets as adults.

The first Mr. Osomatsu anime season premiered in October 2015, and Crunchyroll streamed the series as it aired in Japan. The second Mr. Osomatsu anime season premiered in Japan on TV Tokyo and TV Aichi last October. An anime film is in the works for next spring.

Viz Media acquired the digital streaming, electronic sell-through, home video, and merchandise rights for the Mr. Osomatsu anime, including the second season.
