Guys,
I was in Tokyo Jan 2012 & did experience the soapland at Yoshiwara. The place is called Land Mark (

took the subway to Minowa station and walked to the place on a weekday afternoon.
there was a bouncer outside, you just have to walk right up to him and say Gaijin ok? they are usually friendly and will lead you into the lobby.
there are usually only a few girls that will serve foreigners so the picture book you see will not be like the ones on website. I was only given 3 choices and I chose her (

the only disadvantage is the language barrier... its like chicken & duck talk.
I got 2 shots... one on the slippery mattress while doing the nuru massage
i paid Y75,000 yen, which include the gaijin fee.
I will never do it again cos its F***ing expensive but at least I did the "been there done that" thing.
let me know if you have any questions.
I also know Kings club accepts gaijins.
