This article seeks to analyse the manner in which Korean immigrants navigate their identities in Japan. It evaluates how the characters in Min Jin Lee’s novel Pachinko have hybrid identities, and it goes further to explain how discrimination against Korean immigrants living in Japan is the catalyst in creating the hybrid identity. In an attempt to live a normal life and escape prejudice and criticism, Koreans attempt to adopt the dominant identity. This is the initial point where cultural intersections occur and people become hybridized. The novel Pachinko takes place in the context of historical occurrences, underscoring the various difficulties faced by Korean immigrants in Japan. The researcher tries to demonstrate the complex mechanism of building an identity and the lasting consequences of discrimination against vulnerable groups by examining the nuances of hybrid identity.
