"Saitama City fuzoku job listings" — some people hear that phrase and instantly get it, others don't. (Fuzoku = Japan's licensed adult-entertainment business.)
I'm 42 and still working the floor of this world, so I'll lay it out from a real, on-the-ground perspective.
Why this topic matters
Information about fuzoku is surprisingly poorly organized. Beginners especially tend to end up not even knowing where to start looking.
What this means in concrete terms
In a word: "whether you know it or not changes the quality of the experience."
What I'm writing here is the essence of the knowledge I've built up over 20 years.
