隠し砦の三悪人
was a Japanese writer who wrote over 100 screenplays. He is best known for co-writing screenplays for a number of films directed by Akira Kurosawa, including "Ikiru", "The Seven Samurai", "Throne of Blood" and "The Hidden Fortress". His first film with Kurosawa was "Ikiru", and according to film professor Catherine Russell, it was Oguni who devised that film's two-part structure. Film critic Donald Richie regarded him as the "humanist" among Kurosawa's writers. In 2013, Oguni and frequent screenwriting collaborators Kurosawa, Shinobu Hashimoto and Ryūzō Kikushima were awarded the Jean Renoir Award by the Writers Guild of America West.
