The other day in Ikebukuro, near by the 7-11 on the North Exit is a fashion health place called Tomato Navi. I passed by the entrance and the front door says in English "Japanese Only." Below that, it is written in Japanese that the message is endorsed by the Tokyo Crime Prevention Watch. I don't know if this organization is a volunteer non-profit group or a local government sanctioned watch but it does give me a more direct look at these practices. In most instances from what I have experienced, this mostly due to language issues and in some other instances, fearing that foreigners have diseases. Even if some of the places management allow foreigners on whether or not they understand Japanese, the individual girls still refuse the right to provide services to them. But I am guessing in the past, some foreigners may have caused trouble to the point that they can exclude foreigners under the recognition of such a group. Practicing such exclusion in this industry is one thing and I don't have that much of an issue with it. I don't equate this anywhere near Jim Crow as practiced between post-slavery and civil rights movement in the southern US. I would only have a major issue with it if I go to a local Gusto or use transportation and they do this.
