Sorry, may be to late to the party here. I am not sure Tokyo is GFE central since lots of the reviews indicate ok but rather indifferent service. Now, bearing in mind that I have not been, hentaitokyo.com looks very promising. They cater to westerners and have branches in both Shibuya and Shinjuku. Both Incall at nearby love hotel or outcall. Looks very promising.  

I am headed to Tokyo in two weeks-- so please post your experiences here!

Thanks!

So this whole Asia group is pretty dead, but on the off chance someone is looking, Tokyo Hentai Club rocks. Many fine choices (I did Rina, Honey, and Rika) but get Rika in Shinjuku if u want the real deal Japanese GFE.
