"Fuzoku, open scheduling (jiyu shukkin), Omiya" — some people hear that and know exactly what it means, and some don't.
I'm 42 and still working the floor 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 poorly organized. Beginners especially tend to end up not even knowing where to start looking.
What this actually means
In one line: whether you know it or not changes the quality of the experience.
I'm putting the essence of the knowledge I've built up over 20 years right here.
In closing
