It's less than what I was expecting, but Nintendo has promoted the app, through its official Japanese website, Twitter account and the whole pre-registration, with the beginning of Nintendo Account, was, indeed, a marketing operation. Plus a (small, yeah) mention in the latest Direct. Still, I won't deny that I was expecting some commercials or other marketing initiative alongside what they did. However, what I want to know is how it compares to other apps that are similar in terms of function in Japan: do they get advertised more after launch , and how.
