If there is a Japanese heaven somewhere, I'm sure that at the gate there stands an angel who checks to see if would-be entrants can do the "radio exercise" routine or not.
This must be the only country in the whole world where every single individual, regardless of age or place of origin, knows how to do this one single routine.
デインが笑って Never thought of that.というのですが、まさにそのとおり。
でも、最近の子供はできないかも?
なので、あと10年もすれば、 the only country in the whole world ではなくなるかも。
