Well, 7th Dragon, Maestro! Jump in Music and Nora to Koku no Koubou: Kiri no Mori no Majo (aka Noora and the Time Studio: The Witch of the Misty Forest) aren't the only such titles that are on my radar right now.
In fact, here are four more:
Catch! Touch! Yoshi!--I know I could pick up the North American version of this game--known here as Yoshi Touch & Go--on the cheap, but I really like the Japanese box art so I'm planning to buy that iteration instead. Regardless, I have a feeling I'll like its gameplay, too, once I get my hands on a copy.
Nanashi no Game--Now that this spooky title, published by Square Enix in 2008, has a fan translation, I desperately want to put it through its paces. And who knows, maybe by the time I've finally acquired and finished it, a fan translation will be released for its 2009 sequel (also a Japan-only affair, of course), Nanashi no Game: Me.
Pac-Pix--An odd choice, I'm sure, but I've always been curious about this one--in part because of its extensive use of the DS's touch screen and in part because of its adorably cartoonish art style. The main reason I've yet to add it to my collection is that I have a feeling it isn't the deepest of experiences, but since copies can be picked up for less than $10 I probably shouldn't worry about it so much.
Tomodachi Collection--Another import-only DS game that now has a fan translation--or at least a partial one. Actually, I'd want a copy of Tomodachi Collection even if some of it hadn't been translated into English, as it might help me with my Japanese studies--you know, when I finally back to them.
