"Soapland, beautiful breasts, Toda" — some people hear that and know exactly what it means, and some don't.

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 that actually means
In a word: "whether you know it or not changes the quality of the experience."
What I've written here is the essence of the knowledge I've built up over 20 years.
