I just picked up a Wii Fit today. I have a modded American Wii, and I play both Japanese and American games on it. I decided to get the Wii Fit, as my wife really wanted it. Can't complain when SHE is the one that initiates a video game purchase. Anyways, my question is, should the Japanese Wii Fit work with my modded U.S. system? I don't see any reason why it wouldn't as all of my other Japanse accessories (Wii remote, GC wavebird, etc.) all work with my U.S. system. It would just be a shame if it didn't work, since there are no returns on opened stuff over here in Japan.
