by Natsume Sōseki: A classic novel that explores the themes of loneliness and isolation in the rapidly modernizing city of Tokyo. The story follows the relationship between a young man and an older man who becomes his mentor.

Hailed by The New Yorker as “rich in understanding and insight,” Kokoro—”the heart of things”—is the work of one of Japan’s most popular authors. This thought-provoking trilogy of stories explores the very essence of loneliness and stands as a stirring introduction to modern Japanese literature.
