I didn't even find a really good Japanese massage parlor in San Francisco, although guys who live there must know of some--there are so many Japanese residents there. When I did go there to an Asian place, the girls I saw were mostly Chinese and Korean. I once got the best Shiatsu massage of my life at a Japanese massage place in Los Angeles--by a beautiful young female--but it was a legitimate place whose door was in a bank lobby. There was a dressing room to strip down to supplied boxer shorts, and then the floor pads were side by side (a few feet a part) in a row of about 10 - 15 in one long room. Each pad had its own female masseuse with hand bars above for walking. She even did a strong foot and ankle massage using her own feet--and I was thinking that if she didn't know exactly what she was doing, she would have broken my ankles. Instead, it felt good. I've been to China, but never to Japan. Based on the JAV film industry of Japanese soap girls and other themes, I'm sure that I would love being in Japan. The sexiest AMP experience I ever had in Houston was with a Japanese beauty, but she left to go back to Japan.
I've looked for Japanese massage parlors in New York--once I found a good one in the Japanese neighborhood around 32nd street, but I have subsequently only been able to find Korean and Chinese places there--I would expect New Yorkers to know of some good Japanese places. Of course, I also like Korean places, but there are too few in Houston.
