Japan's post-war constitution, enacted on May 3, 1947, was drafted under the guidance of the Allied Occupation, particularly by the United States. This constitution replaced the Meiji Constitution and established Japan as a constitutional monarchy, emphasizing democracy, human rights, and the rule of law. One of its most notable features is Article 9, which renounces war and prohibits Japan from maintaining military forces for warfare. This commitment to peace has shaped Japan's foreign policy and military stance since World War II, influencing its relationships with countries like the United States and China.
