2. The country was occupied by the United States, with General Douglas MacArthur appointed as Supreme Commander of the Allied Powers (SCAP).
3. Unlike Germany, where the Allied powers directly administered different zones, Japan was governed indirectly through its own institutions, under close supervision by SCAP.
4. The emperor endorsed the occupation and reforms, giving them legitimacy in the eyes of the Japanese people.

2. Political Reforms

   1. Renounced war as a sovereign right of the nation (Article 9).
   2. Prohibited Japan from maintaining armed forces with war potential.
   3. Protected a wide range of civil liberties and human rights, including freedom of speech, religion, and assembly.
2. The emperor remained in place, but his role became purely symbolic, with no political power.

3. Dismantling of the Military and Authoritarian Institutions

1. The Japanese military and secret police forces were disbanded.
2. Officials and leaders involved in militarism and wartime aggression were purged from political office and major industries.

3. The treaty restored full sovereignty to Japan, formally ending the American-led occupation.
4. Japan accepted the outcomes of war, renounced territorial claims, and pledged not to rearm offensively.
