"What is a free information center (muryo annaijo, a storefront that steers customers to fuzoku shops for a referral fee)? A thorough breakdown of how it works, the perks, the job, and the pay!" — some people hear that and it clicks instantly, others not so much.
I'm 42 and still working the floor of this world, so I'll sum it up from a real, on-the-ground point of view.
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 this means in concrete terms
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 the knowledge I've built over 20 years.
