"Kawagoe fuzoku, big busts" — some people hear that phrase and know exactly what it means, and some don't.
I'm 42 and still out there working this world, so I'll lay it out from a real-world point of view.
Why this topic matters
Information about fuzoku (Japan's licensed adult-entertainment business) is surprisingly poorly organized. Beginners especially tend to 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.
I'm putting the essence of the knowledge I built over 20 years right here.
