Last month, the firm released “Miitomo” — a free-to-play and interactive game that allows users to create “Mii” avatars — as it tries to compete in an industry that has increasingly gone online.
Users can customize the avatars’ outfit through in-app purchases and interact with characters created by other people.
“Our first smart device app, Miitomo, was released globally in March and it started off well,” Nintendo said.
The robust start of the smartphone game is good news for the Japanese game maker — long reluctant to stray from its console-only policy — as it looks to turn around slowing demand for its Wii U console.
It did not give further details about new console, codenamed NX.
The announcement came as the Kyoto-based company posted a 16.5 billion yen ($148 million) net profit in the fiscal year through March, down 60 percent from a year earlier.
Revenue was down about eight percent to 504.5 billion yen, it added.
Japanese exporters such as Nintendo have seen their profits, which are calculated in yen, soar in recent years as the unit weakened sharply against the US dollar and other currencies.
The fall made them more competitive overseas and meant the profits earned abroad were worth more at home.
But Japan’s currency has reversed course as a plunge in equities and commodities fueled by fears about the world economy boosted buying of the yen, which is seen as a safe bet in times of turmoil.
