American Girls Or Japanese Girls?

Aesthetically and sexually, I often prefer Japanese girls. However, I would have no idea how to first start to get to know them unless they are very outgoing. I'm better at socializing with American women but am only interested in very few for an actual relationship because it seems hard to find someone I have much in common with.

Japanese girls are confusing and a little too direct/focused on their needs. That's not always a case but in general that's what I've discovered. NOTE: Not talking about jineko here. She's Asian.

People here might judge through anime/AV(Japanese porn) perspective so I'll say this now for everyone. Naturally, Japanese girls are shy and really hold back their feelings for their partner(straightforwardly, cold towards their lover, and the same thing goes for male Japanese) and most of them are really materialistic. In exchange, they're usually good submissive housewives. Not saying ALL of them are, just saying most of them are. That is if the question is with regards to choice of relationship, I think I'd have to go with the_ronery_anon's answer. But if it's with regards to fap material or fetish I guess to each his own.
