'Yasujiro Ozu' and his longtime collaborator 'Kogo Noda' spent 103 days at a country inn in Chigasaka working on the screenplay. After that, shooting and editing advanced extremely quickly, meaning the film was in production for a total of four months.
Although made in the early 50s alongside many other Japanese films now considered classics - Rashômon (1950), Ugetsu (1953) and Gate of Hell (1953) - this didn't receive US release until 1964, by which time 'Yasujiro Ozu' was already dead.
Yasujirô Ozu: [movie posters] Ozu pays tribute to his cinematic influences by putting all kinds of film posters all over the wall in his films. In this movie, there are posters in Noriko's workplace (around 36:42 minutes in), Shige's hairdressing salon (57:00) and finally in the bar (1:12:00). Sadly, these films are hard to identify because the posters are obscured by the parts of the background.
