This article aims to trace the formation processes of modernization in Korea, with special reference to the Japanese annexation of Korea. During the Japanese colonial period, Korean traditional culture was almost totally confronted with the colonial policy and its adoption of Western culture and religions. The modernization of Korea does not just mean comparative concepts of ancient and modern time, it occasionally means that Korean culture was replaced by other cultures. This paper is focused on the Korean individual and national subjectivity, suppressed in the Japanese effort to eradicate Korean national identity. Traditional Korean culture suffered heavy losses, and Koreans were even forced to take Japanese surnames. In this connection, this paper is exploring the Japanese academic efforts to transform the colonial system by adapting modern theories to Korean society especially at Kyungsung Imperial University.
