One Wonderful Sunday (Japanese: 素晴らしき日曜日, Hepburn: Subarashiki Nichiyōbi) is a 1947 Japanese film co-written and directed by Akira Kurosawa. It was made during the allied occupation of Japan and shows some of the challenges of life in early post-war Tokyo. The film is notable in the Kurosawa canon as the director's only shomin-geki, and because of a fourth wall-breaking scene at the climax. It is in black-and-white and runs 108 minutes.
