Sexy Room - Pirates

Walked past this gentelman's establishment tucked away in the side streets near the station.
You can see the Tozai line train in the background.

It's called "Sexy Room Pirates".
Certainly doesn't look sexy from the outside, but looks can be deceiving, and I'm not one to judge a book by its cover.

Gentleman's Relaxation Zone

Not quite offering the services that somewhere like Kabuki-Cho might offer, Koenji still has a small area for the late-night businessman to pop in on his way home from a 16-hour day.

Just a few sex parlours, with some dodgy looking blokes outside to usher you away in case you might have the urge to stray into their "no foreigners" establishments.
