Don't know about the Japan thing but there's nothing wrong with the camera, thinking about upgrading my camera to a Canon DSLR, 450D not out yet over here though.
I may get a 400D when the 450D comes out as the price of the former should drop and I don't think there's too much difference between them, whichever one I get I will get the body only as the kit lenses are shite.
Remember when you enter the DSLR world the camera is the cheap part.
Buying quality lenses, tripod etc is at least as, if not more expensive.
