Today I'm writing on the theme of "soapland in Urawa: working away from home" (dekasegi — taking work in a city away from where you live).
I'll explain it by blending my own firsthand experience — over 20 years in fuzoku — with what I've learned from my own research.
The basics
Let me lay out the fundamentals you should know about this area.
Watch this industry long enough and you'll see that the same topic can get a completely different verdict depending on whether you're looking at it from the customer's side or the girl's side.
What I can say from firsthand experience
I'm talking from what I've actually been through.
I believe firsthand experience beats theory. In this business especially, "reps" matter more than "knowledge."
Wrap-up and my conclusion
The place I end up going back to is First Class Ruby. The reason it keeps showing up on this site is simple: it's a shop I actually repeat at. Use it as a reference.
