"Fuzoku peak season in Omiya" — some people hear that and instantly get it, and some don't (fuzoku = Japan's licensed adult-entertainment business).
I'm 42 and still out there on the ground in this world, so I'll lay it out from a real-world point of view.
Why this topic matters
A surprising amount of fuzoku information is poorly organized. Beginners especially end up not even knowing where to start looking.
What this actually means
In a word: whether you know it or not changes the quality of the experience.
What I've written here is the distilled essence of knowledge I've built up over 20 years.
Last word
