Kizuki’s suicide

Kizuki’s suicide is the novel’s initiating loss and a lasting force in the lives of Toru Watanabe and Naoko. Its stark contrast between an ordinary afternoon and a death no one can explain unsettles Watanabe’s understanding of life, while the absence of a note or discernible motive leaves both the characters and the narrative without a final account of why Kizuki died. The loss returns in Watanabe’s grief, in Naoko’s memories of the person he did not know, and in the novel’s continuing recognition that understanding death does not make bereavement curable.

The Last Afternoon

The day of Kizuki’s death began with an unremarkable decision to skip classes. On a pleasant afternoon in May, he and Watanabe left school, walked down to a pool hall by the harbor, and played four games. Watanabe won the first, but Kizuki grew serious and took the next three. By their custom, the loser paid. Kizuki made no jokes during the games, a departure from his usual manner. When Watanabe asked why he was so serious, Kizuki said he had not wanted to lose that day, smiling with satisfaction.

That exchange gives their final meeting an ordinary closeness, but not an explanation. Nothing Watanabe observed in the afternoon prepared him for what happened later. The disjunction between the familiar friend at the pool table and the death that night becomes central to Watanabe’s retrospective account: the last encounter is vivid, yet it offers no key that would make Kizuki’s decision intelligible.

The Death and Its Immediate Aftermath

Kizuki died by suicide in his garage that night, at seventeen. His parents had been away visiting a sick relative. When they returned to put their car away, they found him dead. The account includes a radio still playing and a petrol-station receipt beneath a windscreen wiper, details of an ordinary setting that do not clarify his motive.

He left no suicide note, and nobody could identify a reason. Because Watanabe had been the last person to see him, police questioned him. He told the investigating officer that Kizuki had shown no sign of what he was about to do and had seemed exactly as usual. The officer appeared to judge both boys through the fact that they had skipped classes to play pool, as though that behavior made suicide seem natural. A brief newspaper item brought the public account to a close; Kizuki’s parents disposed of his red N-360, while a white flower marked his desk at school for a time. The official and visible aftermath ended, but the questions did not.

What Watanabe Could Not Forget

In the ten months between Kizuki’s death and his examinations, Watanabe could not find a place for himself in the world around him. He began a relationship with a girl at school, but it lasted less than six months and did not draw him out of his detachment. He applied to a private university in Tokyo, passed its entrance examination without exhilaration, and left Kobe because he wanted to begin somewhere he knew no one. After moving into a dormitory, he tried to keep a proper distance from everything and to forget the pool tables, Kizuki’s car, and the flower on the school desk. The effort seemed to work at first, but an indistinct knot remained inside him.

As Watanabe recalls it, that knot gradually formed into the recognition that death was not separate from life. Before Kizuki died, he had imagined death as an eventual force that remained elsewhere until it reached a person. The loss broke down that distinction: death was already within the life of the living, and no effort to forget could make it absent. Watanabe came to understand that Kizuki’s death had taken part of him as well. He carried this conviction into the following spring, even as he resisted becoming serious and struggled with the contradiction between treating death as an unalterable fact and fearing that seriousness itself might not bring him closer to truth.

What Naoko Knew

Naoko’s memories complicate Watanabe’s picture of his friend. Kizuki had shown Watanabe his best side, working to conceal his weaknesses because he was fond of him. With Naoko, his lifelong companion, he let his guard down. She remembered him as changeable from childhood: sometimes talkative, sometimes depressed, and often frustrated by his attempts to improve himself. She described his efforts to change as a source of anger and sadness, despite the qualities she considered fine and beautiful in him. Her account does not provide a definitive motive for his suicide; it reveals instead how differently the same person could appear within different relationships.

Naoko also described their closeness as an inseparable childhood bond. They had grown up together with an unusual openness and little sense of distance between them. She believed that, had Kizuki lived, they would have stayed together, loving one another and gradually becoming unhappy. This imagined future is not a claim that their relationship caused his death. It underscores the limits of what a surviving person can know: Naoko can describe the relationship they shared and the vulnerabilities she witnessed, but neither she nor Watanabe can turn those facts into a conclusive explanation.

Recurrence and Significance

The absence of an explanation becomes a painful pattern in the novel, not a puzzle solved by repetition. When Naoko tells Watanabe that her older sister also died by suicide at seventeen and left no note, she sees the deaths as exactly alike. The parallel deepens her grief and her sense of recurrence, but it does not establish a shared cause. Later, Kizuki’s death remains part of how Watanabe understands Naoko’s death, and subsequent losses reinforce the distance between the living person’s desire for reasons and the silence left by the dead.

Watanabe’s eventual formulation—that death exists as part of life—does not release him from grief. After Naoko dies, he reflects that living also means nurturing death, but that this truth cannot cure the sorrow of losing someone loved. In that later reckoning, Kizuki’s suicide is both an early lesson and an unresolved beginning: it changes how Watanabe understands mortality, yet it cannot prepare him to meet the next bereavement. The event’s significance lies not in a recovered motive, but in the way an unexplained death continues to shape memory, intimacy, and the difficult work of remaining among the living.
