I've lived in Tokyo for 20 years and have used most of the agencies and their girls at one time or another. I am more than happy to answer individual questions but I would say without a doubt the two best/most reliable agencies are Nasty Dolls and Asian Mystique. If you are a Japanese speaker, there are some other options as well
A6steve, he participates on quite a few threads on that board and always provides excellent info..
Here's a thread from earlier this year with some solid advice and specific recommendations. I found it by searching that forum for the last two years using "Tokyo." I got several more hits tho wasn't able to look at them.
You might also PM a6Steve, who posted in that thread, he has a lot of first-hand experience throughout the Far East.
Good luck, I hope this helps get you started.
