While we often perceive "Japanese" or "Korean" as fixed categories defined by nationality or lineage, history reveals that identity is a dynamic and evolving construct. This special lecture features Professor Hosanna, who will guide the audience across national borders from the macro-perspective of comparative cultural studies. The presentation deconstructs how nations within the East Asian cultural sphere, specifically Japan and South Korea, have adapted to shifting historical eras to continuously redefine themselves and their concepts of citizenship and belonging.
