The game, released as a Nintendo Switch 2 exclusive and available at retail and digitally via the Nintendo eShop, hit that sales milestone within its initial four-day window, according to a company press release.
Nintendo characterized the performance as a record for its Switch 2 lineup, underlining the franchise's enduring commercial strength on Nintendo's next-generation hardware.
Industry data for the United Kingdom shows the title also delivered a notably strong physical debut.
In the UK, Ocarina of Time recorded the second-biggest launch in The Legend of Zelda series history, with its boxed sales outpacing several recent multi-platform releases, including Resident Evil Requiem, Call of Duty: Modern Warfare 4 and EA Sports FC 27.
Nintendo framed the results as part of a broader celebration for the series' milestone year.
The Ocarina of Time release is among activities marking The Legend of Zelda's 40th Anniversary, commemorating the original game's launch in Japan in 1986.
Nintendo has outlined additional anniversary initiatives, including a worldwide concert tour set to begin in 2027 and a live-action film scheduled to open in cinemas on 30 April 2027.
For retailers and digital storefronts, the Switch 2 exclusive arrived simultaneously at brick-and-mortar outlets and on the Nintendo eShop, giving consumers immediate access to both physical and digital purchasing paths.
Nintendo's announcement did not break down the mix of digital versus physical sales in the stated 5.2 million total.
The early sales figures underscore strong consumer demand for established Nintendo franchises on Nintendo Switch 2 and provide a benchmark for future first-party releases on the platform.
With Ocarina of Time now available worldwide on Nintendo Switch 2, Nintendo's first-party portfolio continues to drive hardware relevance and software sales performance in the current console cycle.
