I agree with most of the list. Tokyo is the first city that comes to mind. I'm not sure about Seoul though, I've heard mixed things about Korean women (sure they are beautiful to look at, but that might be all you'll get to do). I think Hong Kong is good though, and if you don't mind communist China, then Shanghai and Beijing are also good for meeting Chinese women.
In Europe, I think Munich is the best place I've been to (especially during Oktoberfest). German girls are friendly and down-to-earth. London or anywhere in the UK is good if you like British women. Scotland or Ireland are good too. Eastern Europe is really good if you don't mind the 3rd world conditions. Those women love American guys. I wouldn't recommend Italy, unless you're fluent in Italian (well Rome or Milan may not be bad, but I live in Sicily where women who speak English are few and far in between).
There's also Canada and Australia. I would say those are the best places because of the minimal language and culture difference (and UK for that reason).
