When I called for a reservation, the help desk lady told me they run three businesses currently. I asked the details.
1. Erotic Massage Club, they have more than 20 branches in Japan.
2. Fetish Femdom Girls Club, I think this is a kind of "image club" stuff. You are molested by a female musher
3. And they opened health in Tokyo and Osaka. Only 2 branches for a trial, I guess. Japan Escort Girls Club. No, Japanese Escort Girls Club. Not sure.
Personally, I found most services in this health are ready in other two stores except kiss, BJ, anal licking and sumata. So maybe many users want those additional play? Maybe I will try one of the girls in new Tokyo escort girls club sometime.
