"Fuzoku, Kawasaki, play" — some people hear that and instantly get it, and some don't.
I'm 42 and still out in the field of this world, so I'll lay it out from a real, on-the-ground point of view.
Why this topic matters
Information about fuzoku (Japan's licensed adult-entertainment business) is surprisingly disorganized. 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 or you don't know changes the quality of the experience.
What I'm writing here is the essence of the knowledge I've built up over 20 years.
