1.5 Wartime legal system

Japan's wartime legal system underwent significant changes as the nation shifted towards authoritarianism. The Meiji Constitution was reinterpreted to expand executive and military power, while civil liberties were curtailed in the name of national security.

Wartime legislation like the National Mobilization Law gave the government sweeping control over society and the economy. Military courts gained jurisdiction over civilian matters, and strict censorship was imposed. These changes had lasting impacts on Japan's post-war legal reforms.
