On one level this is a love story but on others it provokes thoughts about the differences between city and country, rich and poor, guest and servant.
When Shimamura travels from Tokyo to the snow country there i a sense he has moved to not just a different part of Japan but a place where he can act differently. His relationship with Komako, is the most obvious manifestation of that change in behaviour, with a secret life being led away from his wife and children.
But this is a different area geographically, it enjoys deep snows and feels cut off from his other existence. When he leaves after one stay in the hot springs resort he travels back by train and moves from one zone to another via a mountain tunnel. That shift sees the weather change, the landscape shift and his mental position also move.
But the focus of this story is the hot springs resort and the relationship between Shimamura and Komako,. her story unfolds over the course of a couple of trips Shimamura makes to the town. She has become a geisha to pay medical bills for her lover, forced into a life of pleasuring guests and is stuck in a trap. He on the other hand is financially secure, wastes his time on academic exercises that lead nowhere and is removed from the life of hardship those in the hot springs resort live.
The relationship is doomed and as she slides deeper into the geisha trap and isolation he appears to be less able to save her.
If you read to escape then this takes you to a land of deep snow, hot springs and Japanese customs that will take you into a different realm. Despite being a short novel it leaves you with questions around the main characters, the life the inhabitants of snow country lead and the limits of love and desire to deliver change.
