The 1953 Japanese film directed by Yasujirō Ozu that explores generational conflict in post-war Japan is Tokyo Story.
The film follows Shūkichi and Tomi Hirayama, an aging couple who travel from their rural home to Tokyo to visit their grown children. Their children are busy with work and family responsibilities, and the visit gradually reveals how modern urban life has weakened traditional expectations of filial duty.
Ozu sets this intimate family drama in post-war Japan, when rapid economic change and Western-influenced social ideals were reshaping family life. The story's conflict is quiet rather than melodramatic: the parents are not openly rejected, but they are repeatedly postponed, redirected, and treated as an inconvenience.
Tokyo Story is known for Ozu's restrained visual style, including low camera positions, still-life transitions, and long pauses in conversation. It is sometimes mixed up with Late Spring or Early Summer, other Ozu films about family and change. Tokyo Story was released in Japan on November 3, 1953, and later became Ozu's most internationally celebrated film.
