"Saitama fuzoku, bloomers" — some people hear that and instantly get it, others don't. I figure both crowds are reading this. (Buruma — old-school gym bloomers, a staple costume fetish; fuzoku — Japan's licensed adult-entertainment business.)
I'm 42 and still out in the field 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 is surprisingly disorganized. Beginners especially end up not even knowing where to start looking.

What I've written here is the distilled essence of the knowledge I've built up over 20 years.
