How Many Copies Have the Naruto Games Sold?
Bandai Namco has marked the milestones publicly. In January 2012 the company announced 10 million Naruto games sold worldwide, and unusually, it published the regional split: 4.3 million in North America, 3.8 million in Europe and 1.9 million in Asia. The numbers are a map of the franchise: the West, not Japan, was the Naruto games market.
By December 2019 the Ultimate Ninja series as a whole had passed 20 million copies. The Storm branch then outgrew the family name: in 2024 Bandai Namco announced that the Ultimate Ninja Storm series alone had surpassed 30 million units, and marked the occasion by publishing a celebration illustration drawn by Kishimoto himself, the manga's author publicly toasting his games' success.
For scale, that places Storm among the best-selling fighting game franchises ever made, in company with series that run far more entries. CyberConnect2 achieved it with a licensed anime property, in a genre, the arena fighter, that the Storm games more or less created for anime adaptations.
Reading the regional split
The 2012 regional split explains everything else on the Library's game shelf: why the West got exclusive Wii games built for it, why a Naruto game debuted in America before Japan in 2008, and why North America was nevertheless skipped for Ultimate Ninja 5 when the math stopped working. These games were a Western business run by Japanese companies, and the release map follows the money exactly.
A note on sources
Sales figures in this section come only from Bandai Namco announcements and the trade and fan press that relayed them: the 2012 ten million announcement, the 2019 twenty million series figure, and the 2024 thirty million Storm figure. Retail estimates from chart sites are not used, because a library that documents objects should be as careful with numbers as it is with colophons.
