Kokoro is Sōseki's profound novel of friendship, guilt, loyalty, and the painful inheritance of memory. A young student is drawn to an older man he calls Sensei, whose reserve conceals a past marked by love, betrayal, and remorse. As the narrative deepens into confession, private sorrow becomes inseparable from the end of an era and the anxieties of modern Japan. This modern English translation offers a careful, cleanly formatted edition of Sōseki's enduring masterpiece.
