Here is an interview which specifically expresses that they were glad Smash could support other games and prove Japanese games could resonate with the rest of the world.
Also, at the very least, Nintendo's in probably the best position it has been since like, 2009? A new Pokemon, Animal Crossing, and more is coming out next year, so I think they'll exert more influence in the coming years. Plus Atlus has Persona to show that turn-based RPGs can be successful now, and Nier Automata did fantastically for Square, and was actually only made because they were tired of making Dragon Quest all the time - so maybe now niche Japanese games can rise back to prominence.
We're a long way off from the dark ages of the Wii/360/PS3 era.
