This book examines the role of risk in international relations, including its interactive relationship with domestic civil society, from the case study perspective of Japan's post-Cold War framing of and responses to North Korea (DPRK). Specifically, it focuses on how agency operates within processes of risk recalibration identified with actors such as policy makers, mass media, and civil society stakeholders in reaction to North Korean missile and nuclear tests - as well as their influences upon other related issues.
