Character designer Naoyuki Asano drew the following "ultra teaser visual" for the new movie:

The first batch of advance paper tickets for the movie went on sale on Sunday, and each comes with one of six diferent clear file folders. The same bundle with a MoviTicke card instead of the paper ticket will go on sale on September 16. The ticket and MoviTicke card both feature the visual above.

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.

The Osomatsu-san Ouma de Kobanashi special aired in Japan in December 2016, and Crunchyroll streamed the anime under the title "Mr. Osomatsu JRA Special 2016." The 24-minute special is part of the "Hashire! Oumatsu-san" collaboration between Mr. Osomatsu and the Japan Racing Association. The collaboration also includes a series of six new anime shorts titled "Mutsugo to Ouma no Monogatari" (The Story of the Sextuplets and a Horse). dMatsu-san , the 12-episode short anime spinoff series of the main Mr. Osomatsu anime, premiered on dTV service in January.

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