Well, about the infamous SMB2J/DokiDokiPanic/SMB2USA issue, Nintendo of America was the one that did that, remember that they had a lot on their hands back then trying not to repeat Atari's history... So they did a lot of decisions that affected them later...
The Zelda thing was Miyamoto showing the game to Nintendo HQ, and they being afraid that even in Japan the game wouldn't work...
