This study examines how foreign residents are supported for social participation and literacy in South Korea, which is one of the first to implement a social integration program that encourages early settlement from overseas, and provides suggestions for supporting a policy for such foreign residents in Japan. Focusing on the literacy problem of married immigrant women, which has been increasing in recent years in Jeju, South Korea, the paper analyses what kind of literacy problems married immigrant women are having in their social life and interaction with local communities. And I will examine what kind of support is needed for their social participation.
