The upper-class Toda family gathers to celebrate the 69th birthday of their father, Shintarō Toda Hideo Fujino with an outdoor photoshoot that feels as polished as their carefully curated lives. Soon after the session, tragedy strikes: the father dies of a heart attack, a blow that unsettles the family’s stability and reveals the fragility behind their refined facade. In the wake of this loss, the eldest son Shin'ichirō Tatsuo Saitō announces a harsh truth: their father had acted as a guarantor for a company now bankrupt, and the burden of debts falls squarely on the family. The news triggers a drastic reorganization of fortunes; they sell off almost everything of value, and what remains is a solitary, weathered house by the sea, a constant reminder of what their status once was and what it might become.
Meanwhile, Mrs. Toda Fumiko Katsuragi and her youngest daughter Setsuko Mieko Takamine relocate to live with Shin'ichirō and his wife, while the unmarried second brother, Shōjirō Shin Saburi, seizes an opportunity to move away from Japan to Tianjin, a city tied to Japan’s wartime footprint. The shift in residence deepens the strain and rearranges loyalties within the family, as earlier social norms and expectations begin to feel more constraining than ever.
Tensions mount at the heart of the house. The mother and Setsuko do not gel with Shin'ichirō’s wife, a resistance that becomes sharper as the question of what it means to belong to an elevated social class resurfaces. Chizuru, the married eldest sister Mitsuko Yoshikawa, views these frictions with a wary eye, and clashes arise not only over daily dispenses of generosity but over how a proper woman should behave in a life shaped by privilege. The debate intensifies when the family’s options narrow: Ayako Yoshiko Tsubouchi and her husband offer a possible refuge, but the elder generation’s reluctance and insistence on propriety cause Mrs. Toda and Setsuko to retreat to the dilapidated, unsold house by the sea, a decision that avoids burdening the others while sealing their own precarious future.
As the first anniversary of the father’s death approaches, the family gathers for a ceremonial dinner, a moment that tests loyalties and exposes rifts. Shōjirō returns just in time for the meal and is stunned to find that his mother and Setsuko are living apart from the main group, still by the sea. His rebuke of his siblings—chiding them for not pulling their weight as children and for failing to shoulder their responsibilities—pushes everyone toward a moment of compelled honesty. After the dinner, Shōjirō extends an invitation to his mother and Setsuko to join him in Tianjin, a plan they accept with a quiet sense of relief that they might find a renewed sense of purpose far from the family’s old expectations.
In a final attempt to secure a new future, Setsuko enlists her unmarried friend Tokiko Michiko Kuwano in a matchmaking effort with Shōjirō, hoping love might soften the hard edges of their inheritance and duty. Yet the moment is interrupted when Shōjirō, not fully ready to embrace a new alliance, heads to the beach, leaving the hopeful plan unrealized for the time being. The film lingers on the weight of inheritance, pride, and the choices that define a family’s path, showing how the past continues to press on the present even as individuals seek a different kind of life.
