Smash Bros. Ultimate is an absolute beast in Japan. The game is doing phenomenally well, and it's already managed to squash a previous entry in the franchise. Smash Bros. 3DS has managed to move 2,558,302 units in Japan since launch, and all it took for Smash Bros. Ultimate to top that total was 5 weeks. Smash Bros. Ultimate currently sits at 2,628,087 units sold, and you can bet it'll hit 3 million very easily, and quite soon too. These figures don't include digital sales, but the story should stay the same even if that data was included.
