Nintendo's first mobile app, Miitomo, has lifted off in Japan, pulling in over 1 million users in just three days.
The freemium social app, which lets friends interact with each other using Nintendo's iconic Mii characters, launched on both iOS and Android in Japan on March 17.
A tweet from the official Japanese Miitomo Twitter account on March 19 confirmed that the 1 million user milestone had been hit.
Miitomo is expected to launch globally later this month, with pre-registration already open in the U.S. and UK.
As reported by Bloomberg, the success of Miitomo's Japanese launch gave Nintendo a leg up on the stock market, with shares rising by 8.2 percent in Tokyo on Tuesday - the largest increase since February 2015.
Miitomo is only the first of five smartphone apps Nintendo has agreed to create alongside its mobile partner, DeNA. The rest are slated to release before the end of March 2017.
