The Legend of Zelda: Breath of the Wild is already the most successful Zelda game in Japan since Ocarina of Time.
The title has sold 957,752 units in Japan since its launch, and that does not include digital sales - so overall, the title may already be the best-selling Zelda release since the series began.
Ocarina of Time (N64 edition) sold 1.25 million units in Japan during its entire lifetime.
The data is courtesy of Media Create and collated on Game Design Gazette. The previous second-highest selling Zelda game was the DS title Phantom Hourglass, which managed 907,821 units, which is just slightly ahead of The Legend of Zelda: Majora's Mask.
In Japan, Zelda - alongside Mario, Mario Kart and Splatoon - remains one of the key selling points of the Switch, and it remains in the Top Ten sales charts every week.
