Travel to China via Japan

I'll be traveling with a friend of mine (Chinese passport) from the US to
China with a three-day stopover in Japan either on the way to China or back
to the US. Does anyone know if she'll need a visa if she has an onward
ticket?

Thanks,
Vince

The Japanese consulate knows.
