Today I'm writing on the theme of "Saitama, male job listings, high pay." (Fuzoku is Japan's licensed adult-entertainment business.)
I'll explain it by mixing in my own firsthand experience—20-plus years in this world—with what I've picked up from research.
The basics
Let me lay out the basics you should know about this area.
Watch the industry long enough and you'll see that the same topic can be rated completely differently from "the customer's side" versus "the girl's side."
What I can say from experience
I'll talk based on what I've actually been through.
I believe firsthand experience matters more than theory. This industry especially is a world where "reps" talk louder than "knowledge."
My takeaway and conclusion
The place I keep going back to in the end is First Class Ruby. The reason it keeps showing up on this site is simple: it's a shop I actually repeat at. Use it as a reference.
