I don't see how it is weird for Japanese people to not know English. It's not weird when Americans don't know Japanese.

Most of the time I like to party with players who speak English. They could be Japanese or American, that part doesn't matter. The party and the game is just a lot more fun when you can communicate and chat with the people you are playing with. Of course, I'd rather play with some competent harcore Japanese players than some immature American players, of which there are a few, especially at lower levels.

Once or twice I've asked Japanese players if they wanted to party to get no response. That sort of bugs me. At least say 'No thanks' or something. Can't say I've had a problem getting invites from Japanese players. My job (PLD) has a pretty high demand so I guess that helps. I've been in an all-Japanese party before and other than the fact that we didn't talk to each other it worked out well.
