Nintendo’s Miitomo for iOS tops Japan’s App Store in fewer than two days

For years, industry watchers speculated that Nintendo could rule mobile if it would only make games for smartphones and tablets. And based on how well Miitomo has done in its first week in Japan, we now have proof that the storied Japanese gaming company is primed to succeed on mobile worldwide.

Miitomo hit No. 1 in all categories (not just games) for free iOS apps in Japan today, app marketing intelligence firm Sensor Tower told GamesBeat. It’s tracking Miitomo on its own platform, and the data comes from Japan’s Apple store. Mobile gaming is a $34.8 billion industry worldwide, and $6 billion of this comes from Japan. Nintendo has struggled with its Wii U home console, and sales of its aging 3DS handheld have been tailing off.
