On May 9, 2018, Nintendo discontinued service for its Miitomo smart device app. Miitomo was Nintendo's first smart device app, and we are glad we were able to deliver this unique and fun experience to users. The development and operational know-how we cultivated through the Miitomo app can be applied to the development and operation of future smart device apps and games. We sincerely thank our fans for their support of Miitomo and all our apps, and we look forward to bringing you new experiences in the future.

We see this app as accomplishing a portion of our goal of getting Nintendo IP (in this case, Mii characters) into the hands of consumers across a variety of environments worldwide. At the same time, we've seen the number of ongoing users for the app decrease.

We have decided to discontinue this service so that we can better optimize our operational resources across our entire smart device business.

May 9, 2018 at 12:00am PT. The app (including features such as Friend Suggestions and Miifoto image-sharing) cannot be used or downloaded after that date.

Yes. The service was discontinued simultaneously worldwide.

No refunds will be provided. We announced the discontinuation of service well in advance to give players time to use any remaining game tickets or Miitomo Coins.

At the end of May, users who don’t own a dedicated Nintendo console or have a Nintendo Network ID can create a Mii character through their Nintendo Account settings and/or the My Nintendo website via a web browser. My Nintendo can be accessed by visiting http://my.nintendo.com.

If you linked your Nintendo Account to Miitomo before May 9 you can still use your Miitomo Mii as your Nintendo Account Mii. Its personality and other information do not carry over.

The Mii character will be displayed as the user’s Nintendo Account avatar, as well as in related applications like the Nintendo Switch parental controls and Super Mario Run.

When this feature becomes available at the end of May 2018, users can create up to six Mii characters per each Nintendo Account. If Miitomo or a Nintendo Network ID is already linked to the Nintendo Account, the previously created Mii character will take up one of those slots.

Mii characters can be created, edited or deleted through the Nintendo Account settings.

This feature is compatible with web browsers on iOS, Android and PC.

As of 5/9/18, Miitomo Rewards are no longer available through My Nintendo.

The process would be the same for deleting any app from your particular device.
