it's been five years since the passing of Satoru Iwata, so I thought I'd comb the @shmuplations archive for some highlights... first off, here's Iwata & co. talking about the making of Kirby's Adventure, complete with a drawing of "Iwata Twinkle" shmuplations.com/kirbysadventur… 
this 1999 interview with Satoru Iwata covers a lot of his work at HAL and his own philosophies about game development shmuplations.com/iwata/ his closing remarks remain as relevant as ever
there are also some translated features that include Iwata among many other devs—nothing particularly deep, but it's neat to see Iwata introduced as "the creator of Hole in One Golf (MSX)"

...and that's it for shmuplations, surprisingly, but Iwata's prominence & long association with Masahiro Sakurai and Shigesato Itoi means that the hardcore Smash & Mother communities have translated a ton of Iwata-paraphernalia themselves, should you choose to seek it out
