Paying to get slapped by a girl is not unique

Paying 1,000 yen to get slapped by a girl (both ways) is apparently not as uncommon as previously thought as Japanese blog Coffee Writer writes. This place called Akiba Hizamakura Nurse Station which specializes in head massages while you lie on a girl’s lap is also already offering the slapping service, at the same price of 1,000 yen for both ways too.
Maybe we just didn’t know about it, but it might already be normal in that industry to slap both ways at the standard price of 1,000 yen!
But there are apparently other more wonderful places in Akiba under the same company that owns Nurse Station:

At Akiba Fumikko Gakuen, which basically means Akiba Academy of girls that step (on you), you can get girls in school uniforms to step on you. It’s technically supposed to be a massage, but it’s done by having the girl step on parts of the body.
The girl can change her socks for 1,000 yen too, as an option.

Akiba Girls’ Dormitory is where it simulates you going into a girl’s room in a girl’s dormitory to play with her. She’ll be in her pajamas of course. And when it says “play with the girl” the site doesn’t say what customers would be doing, in what would be a minimum of 30 minutes that would be spent with the girl.
It lists a whole lot of optional activities though, all of which must be paid for on top of the fee to “play with the girl”.
They list activities such as (not a complete list):
…?
Get slapped by every single girl in the girls’ dormitory (3,000 yen)
