Foreigner Radio Taisou Fun
A friend of mine had the pretty rare experience of working in a company that still does the Radio Exercises (ラジオ体操) before starting work each morning.
The video says it all.
Japan is a quirky place.
I once worked in a company which still had the ラジオ体操 music play over the loud speakers each morning and after lunch, but no one actually got up and did anything.
It was weird. Could set your watch to it.
