I was just in Kyoto for two weeks, and spent more time walking, probably, than doing anything else. I never once saw a sign of that kind.

I will say this however, about the Pontocho, which is a particular tourist-infested area of Kyoto because there are lots of geisha [geiko] there: there is some distrust of foreigners, possibly because of a significant amount of rudeness by foreign, as well as Japanese, tourists. As a result, when I walked down the street which contained almost nothing but restaurants and tea houses, a number of the proprietors called out that they had "English menus."

I took this as code for the fact that they admitted foreigners, whereas places without such menus probably either did not admit or at least did not welcome foreigners.

Other than that, in Kyoto, I never saw anything like what you were talking about. Neither did I see it in Osaka, though I spent considerably less time there.

One other thing, and I certainly do not want to preach: in order to increase the welcome of foreigners, I think it would be great if visitors could do everything they could to be aware of the basics of Japanese manners and etiquette. They are very important to the Japanese. One great way to find out about this is on TheJapanChannel.com's "how to" playlist, on youtube. He really has some great tips, and it's worth watching all of the videos.
