I have used Moemoehime (www.moe-hime.com) in Nippori a few times recently, which could be an alternative to Genkai Lovers. Mama-san says they are fine with gaijin customers as long as a they speak enough Japanese. I usually go for the 60 minutes course for 8,000 yen, and I let the Mama-san book the rental room for me. Last couple of times they booked Sweet Memories (http://lovehotel-navi.jp/tt/sweet/hotel_coupon_list/) for me, and last time I remember paying 1,500 yen for 60 minutes. The website pictures are photoshopped pictures of the actual girls, mainly Chinese girl and some Thai. Last time I picked Risa. She is Chinese and speaks good Japanese and English. She is a smoker, C cup, not as slim as in the pictures but not fat. Nice girl, even talks a little dirty in English during the act which I like. Started with CBJ (BBBJ is OK she said) Did mish, doggy, standing and finished off with mish. Play was all good, the only downside is that she is not a good kisser and her CBJ skills could be better. After the deed was done she gave me a decent massage, asked if she could have a smoke (I don't mind) and talked for a bit. All in all a good experience and good value for money.
