Annoying girl bar ppl

I'm assuming these "girls bar" places are strip clubs or secret sex homes but they are annoying because they would approach me every night. What is their deal? Tokyo and cities beyond each night I'm out 1-2 of these weird looking ladies would come out of a tiny alley or the steps and say stuff to me in Japanese. I give them an awkward glare and keep walking. Some grab my shoulder it's getting weird. Thing is I'm obviously white, I'm not attractive, I'm dressed poorly/looks like a hobo so got no money, not drunk. At least the maid cafe maids you can avoid. One of these places it happened right across the street from koban I mean wth.

does that only happen in the red districts or late night in japan? *total weeb only knows what happens in manga* i mean, i think most are strip clubs, but Japanese strip clubs are pretty nice no way to avoid those seedy people, and the less well dressed you look the more they probz think your into hookers

風俗店ですか？ Usually their owners will hire strong black men to threaten customers who don't want to be ripped off.Those foreigners aren't that smart,they enter those bars... Japanese girl/guy bars: drinking and talking to pretty Japanese women/ikemen Ignoring them is okay.They try to "invite" all foreigners to their bars...

Nothing like that happens to me in USA so I'm not really prepared for it other than ignore and keep walking. I've gone 4 times now and it happens each trip but this is first time actually saying something about it. 8-9pm isn't that late and it's not always red light district. They are so tiny so it'll be a basement or floor up mixed in with random restaurants or a hotel.
