How did the us assist japan following world war ii?

After the defeat of Japan in World War II, the United Statesled the Allies in the occupation and rehabilitation of theJapanese state. Between 1945 and 1952, the U.S. occupying forces, led by General Douglas A. MacArthur, enacted widespread military, political, economic, and social reforms. Hope this helps!!!

Japan's U.S.-approved constitution granted full freedoms to its citizen, created a congress and renounced Japan's ability to make war, Getting rid of their army air force and navy. Since this did happen the U.S took responsibility for Japans security. 

Ibelieve it's the pacific islands
