“Constitution of Japan 1946”, A New Japan

Abstract

This paper examines the transformation of Japan’s political and constitutional structure following World War II, with particular focus on the 1946 Japanese Constitution. It traces Japan’s rapid modernization during the Meiji Restoration, its military rise and imperial expansion, and the catastrophic impact of WWII. In response to wartime atrocities, the United States supervised Japan’s post-war reconstruction and occupation, leading to the drafting of a new constitution that redefined Japan’s government as a liberal democracy grounded in popular sovereignty and fundamental human rights. This constitutional shift not only reshaped Japanese society but also contributed to international peace and stability in the postwar era.
