Nintendo's Super Smash Bros Ultimate sold more than 1.2 million units in three days in Japan, according to data from the Famitsu sales tracker.
Famitsu's data indicated that the latest first-party exclusive for the Nintendo Switch sold 1.24 million units between December 7 and 9. The figure is all the more impressive for not including digital copies of the game.
As Siliconera pointed out, this is the best opening week in Japan for any Switch title, and a record for the Super Smash Bros series as a whole. This mirrors the game's success in the UK, where Super Smash Bros Ultimate's also set records for both the Switch and the franchise.
Good software is absolutely central to Nintendo's chances of reaching its high hardware sales targets for this fiscal year, and in Japan at least, Super Smash Bros is having the desired impact.
Nintendo sold almost 280,000 units of the Switch in Japan in that week, up from 107,000 units the previous week. This surge pushed the console's total Japanese sales to 6.1 million.
