Toru Okada and Kumiko marry

Toru Okada and Kumiko marry after Okada approaches her brother, Noboru Wataya, hoping to gain support before seeking her father’s approval. Okada presents marriage as a bond in which the couple can give each other strength and comfort; the novel’s later revelations place that promise against Kumiko’s estrangement from her family and her decision to confront her brother at the cost of her freedom.

The Family Behind the Marriage

Kumiko’s connection to Noboru is a blood tie without a corresponding sense of closeness. He is nine years older, and she spent several years living with her paternal grandmother in Niigata after being sent away from Tokyo at the age of three. Her parents explained the separation as a response to her supposedly delicate health, but Kumiko doubted that account. She had no memory of being seriously ill and suspected that her parents had sent her to her grandmother as part of a family accommodation: a way to ease a feud between her mother and grandmother. In her account, she had been treated like a hostage in that settlement.

After Kumiko returned to her parents’ home, she struggled to feel at home there. Her older sister was the one family member who patiently reached out to her, sharing her room, reading and talking with her, walking her to school, helping with lessons, and comforting her when she cried. The sister died of food poisoning the year after Kumiko’s return. Kumiko later connected that loss to her sense of guilt and isolation, while her parents’ repeated praise of the dead girl—and their decision to put Kumiko into piano lessons after the sister’s death—deepened her feeling of being measured against someone she could not replace.

Choosing a Shared Life

Before the marriage, Kumiko tells Okada that she had wanted a cat but that her mother would not allow one. She describes a life in which she had not been able to obtain what she wanted, until she no longer knew what she wanted at all. Okada answers by telling her that, as an adult, she can choose her own life and begin again. Her agreement is followed, some months later, by their conversation about marriage. The exchange makes their choice more than a change in household status: it frames marriage as an opportunity for Kumiko to claim preferences and possibilities she felt had been denied her.

Okada first meets Noboru when he decides to marry Kumiko. He seeks the brother out before approaching her father, reasoning that a man closer to his own age might help smooth the way. Kumiko cautions him that Noboru is unlikely to help. Noboru agrees to meet only briefly, at a coffeehouse near Ochanomizu Station. At the time he is a college instructor, years before publishing his book or changing his public image.

Okada tells Noboru that he works at a law firm but does not believe the job suits him, and that he is still trying to understand what he should do with his life. He nonetheless says he loves Kumiko and believes the two of them can make each other happy by offering mutual strength and comfort. Noboru listens without responding in any apparent engagement. The encounter gives Okada no sign of the support he had hoped for; instead, it leaves him with an unsettling distrust of Noboru that he cannot explain by any particular remark or action.

Estrangement and Consequences

The marriage does not bring the siblings closer. Okada’s hostility toward Noboru is clear, and Kumiko considers it reasonable; she herself is not fond of her brother. Their blood relationship complicates an otherwise distant connection, while Okada’s later, violent break with Kumiko’s father further separates the couple from her family. Okada tells Kumiko she may visit her parents without him, but she makes no attempt to do so.

The marriage’s significance is ultimately sharpened by Kumiko’s final message to Okada. She admits that she should have told him the truth earlier, but says she lacked the courage and had continued to hope their circumstances would not become so bad. She then explains that she intends to go to the hospital room where Noboru is receiving life support, disconnect the system, wait until he is dead, and surrender to the police. She plans to plead no explanation or defense. Her message transforms the family estrangement that shadowed the marriage into an irrevocable act: the sister who had once seemed distant from her brother now intends to end his life and accept the consequences herself.

Significance

The marriage begins with an ideal of mutual care, but the family histories that surround it resist any simple idea of marriage as a route to belonging. Kumiko’s childhood separation and bereavement help explain why choosing a life with Okada matters to her, while her continued distance from Noboru shows that kinship alone does not guarantee intimacy. The novel returns to the marriage through later disclosures rather than a simple account of its ceremony, setting Okada’s early promise of shared strength beside Kumiko’s final decision to act alone.
