The Asia Democracy Research Network (ADRN) conducted comparative research on AI governance in Japan, South Korea, and Taiwan, recognizing the growing need to examine how these three East Asian democracies are confronting AI-driven threats to democratic institutions. The report offers a wide-ranging analysis of legislative frameworks, public and civil-service engagement with AI, and cross-country policy responses across ten thematic domains. Its findings highlight both the distinct trajectories these democracies have taken and the gaps that remain, providing a foundation for informed dialogue on safeguarding democratic resilience amid the rise of artificial intelligence.
