They have a chance with Europe, but Japan just ain't gonna crack.
They're not selling anything Japan wants, and Japan's shift toward handheld tendencies indicates that no home console touting traditional games is going to do well in the market.
I wouldn't be surprised if SSBB doesn't sell as much in Japan as it should. Then again, I've seen enough Japanese Brawl vids of crappy players that I could believe that causals are mistakenly buying the game...
"I mean, c'mon, Viva Pinata, a game with massive marketing, didn't sell worth a damn to the "sophisticated" 360 audience, despite near-universal praise--is that a sign that 360 owners are a bunch of casual ignoramuses that can't get their heads around a 'gardening' sim? Of course not. So let's please stop trying to micro-analyze one game out of hundreds and using it as the poster child for why good, non-1st party, games can't sell on Wii. (Everyone frequenting this site knows this is nonsense, and yet some of you just can't let it go because it's the only scab you have left to pick at after all your other "Wii will phail1!!1" straw men arguments have been put to the torch.)" - exindguy on Boom Blocks
