Just NintenDO IT.
Miitomo pre-registration is now open as well at miitomo.com. Once you’ve registered your Nintendo Account, the Miitomo pre-registration is literally one click. By pre-registering you’ll receive My Nintendo Platinum Points when the app officially launches in March, which can be redeemed for rewards through My Nintendo.
Fans are now able to register their Nintendo Account right here by using their Nintendo Network ID, Facebook, Twitter, or Google+ login information. If by chance you don’t have any of those (or you just want to start from scratch), you can of course make an account using your e-mail address.
Nintendo Account will be a unified account where you can link your Wii U, 3DS, mobile device, and NX when it launches. Pre-registration for Miitomo is also scheduled to go live on Feb. 17, so keep your eyes out for that real soon. Nintendo’s first mobile game is set to launch next month alongside the brand new My Nintendo rewards program.
The registration process for this account is incredibly simple, and should take no more than a minute or two.
