Radio Calisthenics with Mini Corps Characters

The main attraction of the campaign is Demon Slayer: Radio Calisthenics, a video series in which miniature versions of Demon Slayer characters—referred to as "mini Corps"—perform daily calisthenics. Supported by Japan Post Insurance, the videos are designed to promote healthy daily habits among viewers.

Each video features a different routine and will be released weekly, with a total of five videos scheduled for the campaign. Participants are encouraged to exercise along with the characters each morning and collect virtual stamps as part of the interactive element. The first video will be available on August 1 at 7:00 a.m.

Interactive Videos Include Quizzes and Games

In addition to the calisthenics series, the campaign includes several interactive videos featuring familiar characters from the anime. The Demon Slayer: Silhouette Quiz presents a new character silhouette daily for viewers to identify. Another segment, titled Look This Way! with the Demon Slayer Corps, allows viewers to play the traditional Japanese game “Acchi Muite Hoi” against the mini Corps characters.

These additional video contents aim to provide daily entertainment for fans during the summer season. The campaign is structured to engage audiences through daily activities that blend fun with movement and recognition exercises.

Health and Cultural Roots of Radio Calisthenics

The campaign highlights the long-standing cultural and health tradition of radio calisthenics in Japan. First introduced in 1928 by the Postal Insurance Bureau of the Ministry of Communications as “National Health Exercises,” the routines gained widespread popularity through radio broadcasts by NHK.

In 1951–1952, the calisthenics were restructured into two sets, “Radio Calisthenics No.1” and “No.2,” which continue to be widely practiced across Japan today. Japan Post Insurance, as the successor to the original organization, stated that it remains committed to promoting these exercises as part of efforts to support healthy lifestyles, extend healthy lifespans, and contribute to broader SDGs (Sustainable Development Goals).

In a comment, the company noted: “We will continue to actively promote radio calisthenics to help realize a society where people can lead physically and mentally healthy lives with a high quality of well-being.”
