Your attendance card

How does the Radio Taiso stamp card work?

Finish the full three-minute routine on the home page and you earn that day's stamp — one per day, saved privately in your browser. Consecutive days build your streak, just like the summer-vacation attendance cards Japanese children have carried since the 1950s.

Nothing leaves your device: no account, no cookies, no tracking — the card lives in your browser's local storage. Share your card as an image whenever you're proud of the streak. If you clear your browser data, the card resets — the old cards were paper, after all, and paper was never backed up either.
