The final novel of a trilogy,
Kokoro shares many common themes with its predecessor,
To the Spring Equinox and Beyond (1912) and
The Wayfarer (1912). Specifically,
To the Spring Equinox and Beyond deals with youth and education, while
The Wayfarer, the story of an unhappy marriage, touches on themes of betrayal, distrust, and mental instability. Another recurring theme of Sōseki’s—which he also explores in
Kokoro—is the impact of Meiji-era westernization and modernization on traditional Japanese culture. This theme is in present in novels
Sanshirō and Botchan, each of which, like
Kokoro, also revolve around a troubled, young protagonist. Outside of Soseki’s canon, Yasunari Kawabata’s novel
Snow Country (1935–1937), also often draws comparison
to Kokoro. Set in the Japanese countryside, the novel tells the story of a rich Tokyo man and his relationship with a provincial geisha and explores the relationship between the modern and the traditional, as well as the power of beauty.
Jun’ichiro Tanizaki’s
The Makioka Sisters (1936) also shares many thematic overlaps with
Kokoro. Set in Japan on the eve of World War II, the novel explores the clash between traditional Japanese culture and modernization through the perspective of four sisters as they navigate marriage and family dynamics in a rapidly transforming society.
