We break the details down below.

Mr. Osomatsu is based on the late Fujio Akatsuka’s manga of the same name. The first season hit Japanese TV on October 5, 2015. Yoichi Fujita directed the project at Studio Pierrot. Naoyuki Asano provided character designs, while Shu Matsubara handled series composition.

The series ran into a degree of controversy over two episodes that aired early in the season, resulting in the show’s first episode being pulled entirely and episode 3 being heavily altered to avoid specific parodic references.

Mr. Osomatsu 2nd Season aired in the Fall 2017 broadcast season. Yoichi Fujita directed the new season, with Shū Matsubara reprising his role on series composition.

Crunchyroll streamed Mr. Osomatsu and its second season as a simulcast. They describe the series as:

Mr. Osomatsu is based off of the gag manga series Osomatsu-kun by Fujio Akatsuka, and ran from 1962 to 1969. The series features a set of sextuplets, the Matsuno brothers, with Osomatsu being the oldest brother and leader of the group.

Viz Media currently holds the rights to the Mr. Osomatsu anime series.
