Abstract

Throughout the postwar period, the Government of Japan's (GOJ) definition and interpretation of collective self-defense and Article 9 of Japan's constitution have played a crucial role in how its leaders develop and employ military power. This issue also has had significant implications for its political and security relationship with the United States.
