Where I got success in Tokyo
Speaking no Japanese put me a a huge disadvantage in Japan. So many touts that must be avoided at all costs. Massage parlours have a high chance of delivering HR but that wasn't what I was after. Figuring that the Kabukicho area would be the best area, I entered some of the brightly lit "entertainment" shops but got nowhere due to language barrier and a feeling that I might get ripped off.
So I started visiting massage shops, being very upfront about what I wanted. Obviously I avoided them if they looked legit. It didn't take me long to strike gold in a wide short alley off Hanamichi-dori street. Sorry I can't remember the name. 2 flights up some outside steps. Open 24 hours.
The madam spoke very little English but was very friendly and clearly wanted my business. There was an English menu with varying levels of massage starting at 50,000 Yen (£25) which was likely a basic massage. The top level was 150,000 Yen which was sex. Not on the menu (but available) was BBFS with CIP for 200,000 Yen. I've been a few times and always had a great service from either Chinese or Thai girls, always pretty and thin in their 20's. The "rooms" are separated by thin wood and the doors are a curtain, with a mattress on the floor.
It starts with being showered by the girl and then mind-blowing sex with DFK, BBBJ, BBFS and CIP over the next hour. Then a final shower with the girl.
The place isn't busy with customers at all and I suspect that the girls are genuinely happy to earning some cash. More than they would get back home. They come to Japan for a few weeks at time.
Not cheap but knowing that I'm going to get great service means a lot to me.
