Good start for Kirby. Great legs for Splatoon, Monster Hunter, Mario Kart and (to my surprise) Zelda. Zelda really seems to break one million in Japan.
Comparing the sales for Attack on Titan 2 it seems, that Switch can sell about two thirds of PS4 units in a head-on-head-start (was another game so far released at the same time amongst the platforms?). Seeing the respective userbases this looks not too bad for Switch.
And funny japanese game names:
