Kim Sa-ryang’s literary activities started after his enrollment at Tokyo National University when he was studying German literature. Despite the fact that most of his works are published in Japanese, they are highly regarded for their elaborate projection of Korea’s reality of the time and the portrayal of the Korean people’s deep-rooted pain that existed due to imperial colonization. Written in Japanese and nominated as the candidate for the Akutagawa Award in 1940, "Into the Light" is a masterpiece that accurately details the discrimination and sorrow experienced by colonized Koreans living in Japan, the duplicity and distorted desire of Koreans who were trying to hide their Korean identity, and the immutable, yearning for one’s Korean mother.
