Kousei Yagi

Born in 1930 in Hyogo Prefecture and educated at Tokyo University of Education — there's a certain old-school gravitas to Kousei Yagi before you even get to the work. He straddled both live-action acting and voice work, which tells you something real about his range: you don't get handed voice roles just because you can stand on a stage, you have to own the sound itself. Coming up through the postwar Japanese entertainment scene means he was working when the whole industry was reinventing itself from scratch, which had to forge a particular kind of toughness and adaptability in a performer. I honestly feel like the depth of what he must have seen and done across those decades dwarfs whatever the data here can capture.
