This is very UNcommon to see in Japan.

There was a famous lawsuit in Hokkaido about a public bath that started banning foreigners because the local Russians kept coming to the bath drunk and drinking vodka, when it was against the rules.

The ONLY places I have seen this are at cabarets, strip joints and pink salons. The reason usually is that the Japanese customer doesn't want the girls at the club to be tempted or fraternizing with foreigners. It's not racism as much as inferiority complex.

Also those kinds of places are stupidly expensive, and you don't know the price until you leave. Japanese people usually won't make a scene when they get the bill, but foreigners have been known to when they are presented with a, for example, 500 dollar bill, per person, after an hour of drinking.
