A Chance Meeting in Kamakura

Left on his own in Kamakura after the friend who invited him is called home by his family, the narrator continues his routine swims in the sea. One day he notices a man at the changing house preparing to enter the water with a foreign guest, and thereafter sees the same man alone each day.

Parting in Kamakura

As the vacation ends, Sensei prepares to return home to Tokyo, and the two part ways. The narrator asks whether he may call on Sensei at his home sometime, and receives an affirmative answer, though a noticeably less enthusiastic one than he had hoped for.

Becoming Close to Sensei

Weeks after his own return to Tokyo, the narrator makes his first visit, only to find Sensei away. On a later visit, Sensei's wife reveals that her husband makes monthly trips to the gravesite of a friend. Over subsequent months and years, the narrator comes to know Sensei and his wife quite well, but Sensei keeps his distance, refuses to discuss his reclusion, and warns that admiration leads only to disillusionment — while promising that one day he will divulge the full story of his past.

Graduation and a Father's Illness

After graduating, the narrator returns to his family home in the country, where his ailing father enjoys a brief respite.

The Emperor's Death and an Unanswered Letter

From his bed, the narrator's father follows the papers as Emperor Meiji declines and eventually dies. After the Emperor's passing, the narrator's mother presses him to secure employment to ease his father's mind, and at her urging he writes to Sensei asking for help finding a position in Tokyo. Expecting no favorable answer on the job but at least some reply, he is disappointed when no response of any kind arrives.

General Nogi Follows His Emperor

With summer wearing on, the rest of the family is summoned home in anticipation of the father's final hour. News arrives that General Maresuke Nogi has committed junshi, taking his own life to follow his Emperor in death. All who hear of it are deeply moved by the act.

A Summons Refused

Shortly after Nogi's death, a telegram arrives from Sensei summoning the narrator to Tokyo. Unable to leave his dying father, the narrator refuses the request, first by telegram and then by a letter detailing his situation. Some days later, a thick letter arrives from Sensei by registered mail.

The Promised Letter

Stealing away from his father's bedside, the narrator opens the thick registered letter and finds that it contains the long-promised account of Sensei's past. Leafing through the pages, a line near the end catches his eye. It reads: 'By the time this letter reaches you, I'll be gone from this world. I'll have already passed away.'

Boarding the Train to Tokyo

Alarmed by what he has read, the narrator rushes to the station and boards the first train for Tokyo. Once on board, he takes out Sensei's letter and reads it through from the start. The letter opens with Sensei's explanation of his reticence over the summer and the motivation behind his final act, before turning to the account of his life.

Loss and Betrayal in Sensei's Youth

Sensei's letter recounts how he lost both parents to illness while still in his late teens, inheriting the family's considerable wealth as an only child. His uncle, entrusted with managing the estate during his years of study in Tokyo, quietly poured much of the fortune into failing businesses. Upon discovering the deceit, Sensei salvaged what remained, arranged the sale of his house and possessions, visited his parents' gravesite one last time, and severed all ties with his hometown and relations.

Love at the Boarding House

Seeking calmer quarters, Sensei trades his boisterous student lodgings for a quiet boarding house run by a widow who lives there with her daughter and a maidservant. He falls in love with the daughter at first sight, yet his uncle's treachery has left him so distrustful that he cannot bring himself to ask the widow, who treats him as family, for her daughter's hand.

K Arrives and Rivalry Grows

Sensei persuades his struggling friend and former classmate K — disowned after abandoning medicine for religion and philosophy — to move in as a second boarder. K gradually warms to the household and grows more sociable, but Sensei begins to see him as a rival for the daughter's affection. During a walking tour together on the Boshu peninsula, Sensei is tormented by suspicions that K is drawn to the daughter, yet he lacks the courage to confess his own feelings.

Confession, Betrayal, and K's Suicide

K finally confesses his love for the daughter to Sensei, who is shocked and unable to muster a response. Sensing K's vulnerability, Sensei reminds him of his own ideals of discipline and servitude to a cause, then secretly asks the widow for her daughter's hand and is accepted, leaving K unaware until the widow informs him and scolds Sensei for the secrecy. Resolving to speak with K the next morning, Sensei instead finds that K has taken his own life during the night, leaving behind a note devoid of the rebuke he dreaded.

Marriage and a Life of Reclusion

Sensei arranges for K's burial in Zōshigaya Cemetery with the family's approval, and shortly after, he and the ladies relocate to a new house. He finishes his studies and marries the daughter half a year later, yet his betrayal of K casts a lasting shadow over the married life, one he can never share with his wife. Having lost faith in humanity and ultimately in himself, Sensei withdraws from the world into an idle, reclusive existence while making monthly pilgrimages to K's grave.

Sensei's Final Decision

Over the years, Sensei comes to realize that K's suicide was less about lost love than about alienation and disappointment in oneself, and he feels himself drawn ever more toward his friend's path. With the ending of the Meiji era and the passing of General Nogi, Sensei decides that he has outlived his time and must part from the world. His final request is that his wife never know his story, and that the account remain private until after she is gone.
