This is true and false. Through one Chinese friend I have been made aware of a Japanese only culture here in the tri-state area consisting of hostess clubs, escorts, and spas. According to my friend such places are even restricted against other Asians gaining entry. They truly keep to themselves, and this was also confirmed by a friend of mine who works for a Jap corporation in Jersey City. Flop, the place you reviewed was primarily catering to Japs, and because of economic slowdown he is expanding to non-Japs. This is a big risk, because most Japs will not follow, they will feel the waters are polluted. Besides they feel if the girl remains within the fold she is most likely safer for BBFS, etc. Furthermore, if you are fortunate enough to have a Jap, or Asian, friend willing to get you into such a spot, it will be very apparent that you cannot spill the beans otherwise you lose your ability to gain access.
It is far easier to get a Japanese girl dressed as a twenty-something afro-am hip-hop youth than getting into any Jap only illicit sex establishment. Also, note that they tend to be very expensive places to play. My buddy said each guy in his party of five blew between 500 to 1000 each at the Jap hostess bar, and the girls were available for outcall for another 300 and above.
Best,
