What is Osomatsu-san? Birth and Background

"Osomatsu-san" is a TV anime that began broadcasting in 2015, and is based on the masterpiece "Osomatsu-kun" by Fujio Akatsuka, a gag manga artist representing the Showa era. The sextuplets, who were once elementary school students, are revived in the present day with the shocking setting that they remain NEETs even as adults.

This anime is not just a remake, but a bold reconstruction as a slapstick comedy about trashy adults living in modern society. Characters from previous works are also arranged in a modern style, providing new appeal to fans of the old works.

Since the beginning of the broadcast, its outrageous development and strong parody sense have become a hot topic, and it has gained explosive popularity mainly on SNS. It has gained many fans, especially among young people, and movements such as "Oshimatsu culture" and "○○Matsu girls" have been born.

The series has aired up to the third season so far, and has been a rich media mix, including a movie version, merchandise development, and a live-action film. Further new developments are expected in 2025, and the series continues to evolve.

Relationship with the original work "Osomatsu-kun"

The basis of "Osomatsu-san" is the classic gag manga "Osomatsu-kun" created by Fujio Akatsuka in the 1960s. "Osomatsu-kun" gained immense popularity, especially among elementary and junior high school students, as a comedy about the daily lives of the Matsuno sextuplets.

At the time, the sextuplets were all drawn with almost the same faces and personalities, and the characters around them, such as Iyami, Chibita, and Dekapan, were more distinctive and stood out.

On the other hand, in "Mr. Osomatsu," the sextuplets are given individuality, and each character's depth and differences are clearly defined. For example, the eldest brother, Osomatsu, is a gambling-loving, irresponsible leader, Jyushimatsu is a high-tension baseball fanatic, and Todomatsu is a cunning younger brother who tries to impress the girls. The characters are so distinct that you can choose your favorite.

In addition, the supporting characters that appeared in the previous work have been remade in a modern style and are making a comeback. Iyami's "Shee!" has been recognized as a famous gag that is still popular with the Reiwa generation, and is loved by many fans. In other words, "Osomatsu-san" is an evolved form that has been boldly updated while firmly inheriting the world view and characters of the original. The exquisite blend of nostalgia and newness is one of the reasons why it is loved by generations.
