This study examines forms of nationalism that have been produced/reproduced in Korean society in the discourse on the Korean Wave phenomenon that occurred in Japan since the 2000s. Since its liberation, Korean society has been building various national discourses on Japan and has promoted nationalism within its own country. However, the construction of Nationalism as an ideological device has produced a national discourse along with the transformation of the social background of the 2000s. This study focused on this situation and examined what kind of national discourse of the Korean Wave phenomenon in Japan has been established in Korean society. Through this process, this study aimed to examine how nationalism has been spreading in Korean society since the 2000s. Consequently, through the drama Winter Sonata that sparked the Korean Wave phenomenon in Japan, he insisted that the male protagonist became a celebrity and played a role in establishing the national identity of Korean society. This view departs from the assertion that national-centered nationalism is declining due to the influence of post-Cold war society and globalization, and that it evokes national identity through individuals. This perspective is intended to emphasize that even if the existing social structure is transformed, nationalism is being produced and reproduced in a constantly modifying form.
