Analyzing the Public Diplomatic Value of Korea-Japan Sports Exchange: A Case Study of the Yonsei-Keio Football Exchange Match

This study analyzes the civil diplomatic functions and effects revealed in the historical development of the regular football exchange matches between Yonsei University and Keio University, aiming to show the value of Korea-Japan sports exchange as civil diplomacy. To examine the historical changes and social impact of these exchanges, a literature review, document analysis, and in-depth interviews with ten coaches, executives, and committee members were conducted. First, the study found that matches held before diplomatic normalization formed the foundation for sports exchange and helped advance bilateral relations. Their voluntary, non-governmental nature maintained political neutrality and strengthened diplomatic effectiveness, complementing the limits of official diplomacy and fostering goodwill. Second, the matches promoted civil-level friendship by creating direct contact and shared experiences between university teams, building mutual trust and positive perceptions. Informal interactions also expanded interpersonal networks, reinforcing individual friendships and broader mutual understanding.
