Nintendo account was released officially today in Japan, for Japan gamers this means linking all of their devices, from Nintendo and not from Nintendo, together in one account system. This’ll be helpful later on when they release My Nintendo and Miitomo. My Nintendo will reward Gamers for not only buying Nintendo products, games and apps but also for playing & using all of them. This account system will most likely keep track of all the usage data to use with reward points in My Nintendo. Miitomo will be most likely one of the apps we’ll be rewarded when using, so the account system will link the phones with the consoles and collect usage data of all Nintendo products to reward the player. If you’re in Japan we hope you enjoy the new account system, if you’re anywhere else then we understand the pain of waiting for this new account system. Miitomo and My Nintendo will both be out in March 2015 here in the US.
