Any NA members gunning for such a bizarre goal? No clue how costly that effort could be. As I understand it Nintendo has localized around a dozen retail titles to the language. Like Wario Land 4, New Super Mario Bros, etc. And brought several hardware models there (GBA / SP / micro / DS / DS lite / DSi). Making for a tiny boxed library. Not sure if 3DS is really out yet as western news sites suggest, I didn't see mention on the iQue homepage.
I've used google translate to make sense of this page with a few good pics.
