SynopsisPlot
Sensei, a man seen against the rich background of old Japan entering the modern era, is outwardly successful. He has position, wealth, a charming wife. But deep in the heart of things, he is harried with a profound sense of isolation whose cure lies only in "faith, madness, or death." His long-hidden secret, divulged to a young friend who faces a similar dilemma, is told with mounting intensity.

Story

About this book

Kokoro, a novel by Natsume Soseki, follows the relationship between a young man and an older figure he refers to as Sensei. Set during a period when Japan was shifting from its older cultural traditions into a modern era, the story is shaped by the tension between these two generations. Sensei appears outwardly settled, with a wife, social standing, and material comfort, yet he carries a deep sense of isolation that colors his daily life.

The young narrator is drawn to Sensei without fully understanding the older man's withdrawn nature. Over time, Sensei begins to share fragments of his past, particularly events from his own student years that left him burdened with guilt. The novel builds slowly around this disclosure, exploring how moral weight can persist across decades and how difficult it can be for one person to truly grasp another's inner conflict.

The title, which can be translated as heart, points to the emotional and psychological core of the book. Soseki wrote Kokoro late in his life, and it became one of his most widely read works. The story is structured in three parts, each shifting perspective and gradually narrowing toward the source of Sensei's long-held secret.
