Been to all three places.Its hard but you can find ladies there.Do some reseach on the web before you go.It will cost you big bucks so keep it mind.Depends where you are staying in Osaka I can tell you some great bars and easy to pick up some ladies in the bar.Most clubs the offer extras wont let you in. The door man will turn his back to you you just need to walk away and try to get in.If you know someone there you may get in.I always stayed at the Ritz.So things do around there.
