Japan’s Cultural Diplomacy in Southeast Asia: Soft Power Strategy and Multidimensional Impacts

Abstract

Japan’s cultural diplomacy in Southeast Asia underwent a significant transformation under Prime Minister Abe Shinzo, evolving from a peripheral promotional activity into a central pillar of foreign policy designed to operationalize the doctrine of “Proactive Contribution to Peace.” This article examines the strategic objectives, institutional mechanisms, and policy instruments that defined this trajectory, focusing on the “Cool Japan” strategy, the MEXT scholarship framework, and the JENESYS youth exchange program. By systematically mobilizing creative industries alongside educational and people-to-people exchanges, Japan succeeded in projecting an image of a dynamic, reliable, and responsible nation, consolidating its position as a trusted strategic partner within ASEAN. The findings indicate that Japan’s cultural diplomacy was remarkably effective in fostering strategic trust, stimulating the creative economy, and embedding cultural values into regional relational structures. The commercialization of cultural assets such as anime, manga, video games, and Washoku cuisine generated substantial economic benefits while establishing a sustainable ecosystem of soft power, particularly resonant among ASEAN youth. At the same time, educational initiatives and grassroots exchanges created durable intellectual and social networks that reinforced Japan’s normative leadership and contributed to the construction of a trust-based regional order. However, the study also identifies inherent limitations and emerging challenges. Japan continues to face intense competition from South Korea’s Hallyu wave and China’s Confucius Institutes, both of which deploy alternative models of cultural influence. Internally, risks of over-commercialization raise concerns about the erosion of authenticity and philosophical depth in Japan’s cultural heritage, while uneven audience segmentation leaves rural and marginalized communities underrepresented. These dynamics underscore the need for recalibration toward greater inclusivity, personalization, and multilateral collaboration. By situating Japan’s cultural diplomacy within the theoretical framework of soft power and Indo-Pacific geopolitics, this article contributes to International Relations scholarship and offers policy implications for developing countries seeking to elevate cultural diplomacy as a strategic instrument.
