The Wii was also released in America before Japan, so I guess it's becoming somewhat of a tradition. Plus, the Wii U's launch lineup has more Western-developed games/Western-oriented games, so it make sense for it to launch in that territory first. If the Wii U's lineup was chockful of Japanese RPGs and pervy anime games, it probably would've come out in Japan first, but as you can see, that's not the case.
