I KNOW I have a clip from a Japanese TV show of this somewhere. It's crazy what they get away with airing over there. Anyway you don't see too much, it's very clinical. It's 2 guys, the tv host plus the guy explaining whats what, and the massage girl, but you get a pretty good idea what the service entails... I remember the end of the clip made me want to book the next flight to Japan, Then I remembered I was broke. So I calmed down...

I'll see if I can find it...
