You'd be surprised. I'd say the vast majority of URLs I see around in Japan end in .jp. Hitting ctrl+enter after an URL will add www and .co.jp on most computers, not .com. Few people understand english sufficiently to browse the english-speaking internet; the best example is probably Facebook, which is rarely used here, while its local equivalent mixi.jp is extremely popular.

Also, the QWERTY keyboard is just not the standard worldwide...

That being said, I don't think people will start using japanese URLs much. The alphabet + .jp is already ingrained and more convenient. Also, most phones will refuse japanese characters in an email adress and perhaps in an URL, which is a game breaker here.

Facebook has extraordinarily good localizations, done primarily by their active users: http://www.facebook.com/translations/

Japaneses tastes are quite different when it comes to design, anonymity, and personal privacy -- and the divergent social network doesn't help anything.
