Masao Maruyama

Masao Maruyama is the kind of person anime fans should know by name but rarely do — a behind-the-scenes producer who joined Mushi Production in 1965, co-founded Madhouse in 1972 and shaped some of the most ambitious animation in Japan over the following decades, then did the whole thing again by launching MAPPA in his seventies, which honestly is one of the most quietly audacious career moves in entertainment history. Born in Shiogama, Miyagi — a coastal fishing town — and educated at Hosei University, he came up in an era when Japanese animation was still figuring out what it wanted to be, and he helped it grow into something the whole world eventually took seriously. He's not the director, not the voice actor, not the face on the poster; he's the person who looks at a pitch and bets on it, who finds the talent and gives them room to work. The fact that he started over at an age when most people are long retired, and that MAPPA went on to produce some of the most talked-about titles of the 2020s, tells you everything about the kind of stubborn, genuine love for the craft this man carries.
