Nintendo Account registrations are now open, marking the start of a new online approach for Nintendo.
Nintendo Account will unify corporate properties in a whole new way!
The new service will connect all Nintendo games and services to their consoles, PCs, smartphones and tablets. We don’t know how the new accounts will work, but the first time they’ll be used is in the next app, Miitomo.
Miitomo is a social networking app for Nintendo fans. He uses Miis to communicate and interact with others. It will also be Nintendo’s first foray into the mobile market. Miitomo registrations are also available, but you must first have a working Nintendo Account.

Can’t forget the classics!
In addition, incoming is the successor to Club Nintendo, My Nintendo Program. It will work in much the same way: players will collect points and redeem them for prizes and rewards.
Nintendo is updating its networking systems extensively. the mobile initiative will lead the charge, followed without doubt by the NX and its innovations. This will hopefully be a big improvement over the Nintendo Network which has been struggling for several years now. Gamers are clamoring for a better way to play games like Smash Bros., Mario Kart, and Splatter online, and I hope the Nintendo Account system fixes that.
The Nintendo Account will officially launch with Miitomo later this year, while the My Nintendo program is slated for release in March.
