"Warabi fuzoku jobs, private standby rooms" — some people hear that phrase and instantly get it, and some don't.
I'm 42 and still working the floor of this world, so I'll lay it out from a real-world point of view.
Why this topic matters
A surprising amount of the information out there on fuzoku (Japan's licensed adult-entertainment business) is poorly organized. Beginners especially tend to end up not even knowing where to start digging.
What this actually means
In a word: knowing or not knowing changes the quality of the whole experience.
What I've written here is the distilled essence of 20 years of accumulated knowledge.
