Coming into force six months later as an amendment to the Meiji Constitution of 1890, the current supreme law of Japan was promulgated on this day in 1946, drafted primarily by American civilian officials of the occupation after the country’s unconditional surrender. The document provides for certain fundamental human rights and the supremacy of the parliament (the national Diet, favouring the British model though eliminating peerage with the upper house, like the House of Lords, formerly restricted to the nobility), reducing the role of the emperor to a symbolic head of state with only a ceremonial role. Also referred to as the Peace Constitution (Heiwa-Kenpō, 平和憲法), its composition was supervised by Douglas MacArthur with input from Japanese scholars and subject matter experts, Article 9 renounces the country’s right towage war or raise armies despite its military capabilities and sending forces in presence of a substantial American military presence. Sovereignty restored in 1952, attempts for further revision were frustrated over a number of legal hurdles and the requirements for change built into the system.
