My opinion;

This is only reflecting the real world.
In the real world there are tons of guys who lust after Asian women and see them as nothing but sex objects. They see a visit to Japan (or another Asian country) as a chance to have sex with them.

And... Unfortunately, a lot of the time, they do just this. There are bars which cater to this - usually with a set of women hanging out in them who will screw any foreign guy who comes along (which is why they`re hanging out in the bar). This gives these guys a skewed perception of Japan, which they then pass on, leading to even more guys who think that they`ll be able to get lots of action.

It`s kind of sad how often that type of guy ends up staying longer in Japan, marrying a normal girl who actually fell in love with him through work or the like, and being unable to give up the "screw gaijin bar girls" lifestyle... leaving his wife (and often kid) to suffer. Or in even worse cases, marries her, takes her back to his country, and expects her to be his personal sex toy.

The real world is a pretty pathetic place.
