Trained in Berlin, he was a pioneer in introducing the theatre of Bertolt Brecht to Japan, translating and directing seminal works such as *Life of Galileo* and *The Threepenny Opera*, and profoundly shaping the country's modern theatre scene. His career also included acting, with roles in notable films such as Akira Kurosawa's *The Bad Sleep Well*. For his outstanding contribution to the Japanese performing arts, he was awarded major honors, including the Asahi Prize in 1965 and the title of Person of Cultural Merit in 1984, accolades that attest to his lasting impact on the nation's culture.
