Some good advice; I, too, would make referrals to Hawaiian Girl, Angel Massage, and Happy Girl. I have not seen, but heard good things about Ayumi (supposedly Japanese) at Hawaiian Girl; have made many visits with Ruby (Korean) and some with Connie (also Korean) at Angel Massage; and have seen Ruby (again, Korean) and Nana (real Japanese) at Happy Girl. I am of Japanese descent, and speak the language, so I can vouch for the authenticity of Nana, she is from Sendai (north of Tokyo), if I remember correctly. Would suggest trying Hawaiian Girl or Angel Massage, as they are in close proximity to each other; so whichever you should visit first, if there is not a good lineup at the time, you could easily just go down the street to the other establishment to see theirs.
