Wow, the Japanese must be stepping it up a notch. There is another educational game for the Nintendo DS: Minna no DS Seminar: Kanji Power! Now, this teaches the use of the Kanji characters properly from writing it to learning the Kanji counterpart of a particular Japanese word. Like English Power!, this game saves your learning progress throughout the game and also the release date is the same (July 6). This is really good practice to those studying Japanese so when this game is released, it's time to talk to your nearest importer.
