>>714396967100% sure, that's shot at Okubo Park in Shinjuku.
There's pretty much two groups of tachinbo (street girls) standing at these streets.
The girls that are mentally ill and do it for the sex/love and to "feel" desired and whatever, and the ones doing it casually here and there a couple times to earn some cash on the side for something they really want.
"Career prostitutes" that really want to make a living and earn big bucks would never fly solo like that. It's simply far too risky in so many ways, much easier to just sign up to a delivery health service and get regular high paying customers while having people look out for you that will step in if a client makes problems.
