Playing SSF4 PC in Japan. (problems)

Hello,
I’m not sure if this is the right forum to post this in, but I need help with the matchmaking here in Japan. I recently just moved here and whenever I boot up AE and try to play online, it’s still matching me with US players. I’ve already set my region to Japan on Xbox.com, but that doesn’t seem to have helped. My Windows Live profile still says that my Country/Region is United States.

Can anyone help me with this?
