Kōichi Yamadera

I genuinely don't think the word "voice actor" is big enough for this guy. Kōichi Yamadera is the human Swiss Army knife of Japanese dubbing — he's the Japanese Donald Duck, the Genie in Aladdin, Stitch, Jim Carrey's go-to dub voice, and somehow none of those sound remotely like each other. They call him the "seven-colored voice," but honestly that undersells it; I've heard him flip from a cackling cartoon duck to a tender dramatic lead in the span of one scene. What gets me is the warmth underneath all that range. Pop on a morning kids' show and there he is, grinning like everyone's favorite big brother, that easygoing Shiogama-in-Miyagi friendliness just radiating off him. Making people laugh and cry with nothing but your voice? Almost nobody pulls that off. He's a national treasure and I'm only half joking.
