I would recommend that you go all the way or try your skill in picking up chicks when it comes to sex in the south.
The cheaper soaplands are quite disappointing, more so than the tokyo ones, like Ariel where you can really get a shite girl.
If anyone is keen, this place below accepts foreigners but YMMV as I can speak Japanese (although a local can tell I am a gaijin)
