The history of Radio Taiso
From a 1928 radio experiment to a daily ritual for millions — and the summer stamp cards every Japanese child remembers.
When did Radio Taiso begin?
Radio Taiso first aired on Japanese radio on November 1, 1928, launched to commemorate the enthronement of Emperor Hirohito and inspired by radio exercise programs broadcast in the United States in the 1920s.
The idea traveled: employees of Japan's postal life-insurance bureau had seen Metropolitan Life Insurance sponsor morning exercise broadcasts in American cities, and proposed the same for Japan — a national health habit delivered through the era's newest mass medium. NHK carried it, the postal insurance system promoted it, and within a few years morning calisthenics by radio had become a nationwide routine.
Why was Radio Taiso banned and then reborn?
After World War II, occupation authorities suspended the broadcast in 1946, wary of its use for regimented mass drills. It returned in its modern form in May 1951 with new, gentler music and movements designed purely for health.
The reborn Radio Taiso No. 1 — with music by composer Tadashi Hattori — was deliberately re-designed around individual well-being: a slower, friendlier march that ordinary bodies of every age could follow. That 1951 routine is essentially unchanged more than seventy years later, one of the longest-running daily broadcasts in the world. Radio Taiso No. 2, a brisker version for workplaces, followed in 1952.
What is the Radio Taiso stamp card?
Every summer vacation, Japanese children gather in neighborhood parks at 6:30 a.m., do the routine together, and receive a stamp on an attendance card (shusseki card) for each morning attended — a tradition running since the 1950s.
A full card often earned a small prize — a pencil, a notebook — but the real prize was the habit and the neighborhood itself: sleepy kids, grandparents, and the one adult with the boom box, all bowing to each other as the music ends. The stamp card on this site is a digital tribute to that ritual. Do the routine, collect the day's stamp, keep the streak.
Is Radio Taiso still practiced today?
Yes — NHK still broadcasts it every morning, an estimated tens of millions of people in Japan do it at least sometimes, and companies, schools, and municipalities keep it as a shared daily ritual.
You'll find it opening factory shifts, punctuating school sports days, and gathering retirees in parks in every prefecture. It has also quietly gone global, carried by curiosity, nostalgia, and the growing science on brief, regular movement. This site exists to hand the tradition to the rest of the world's mornings — in any language, any time zone, any pace.
