This comes up again and again. I lived in Japan for over three years and go back and visit yearly. In that time only once did I see a sign like that, and it was on the door of a pink salon ("massage" parlor).

For an essentially homogenous society, in my experience the Japanese people I dealt with were very open and open-minded. I see a LOT more racism in the US than I ever experienced in Japan.
