In Haruki Murakami's "Norwegian Wood," the rain enhances the vibrancy of the surroundings, creating a unique atmosphere. The colors become exceptionally bright, contrasting beautifully with the wet landscape. The black ground and the vivid green of the pine branches highlight the freshness that rain brings, transforming an ordinary scene into something extraordinary.

The depiction of people in yellow rain gear adds a mystical element, as they appear almost ethereal. They resemble special spirits permitted to roam the earth solely during these rainy mornings, suggesting a momentary escape from reality and a connection to something deeper and more beautiful. This imagery encapsulates the novel's themes of memory, longing, and the fleeting nature of life.
