Explanation:

Because the US had destroyed Japan's national infrastructure to force it to submit to occupation. It was now responsible for the people there. It had promised that the Japanese would not be enslaved and would be allowed to rebuild in the Potsdam Declaration.

Goals for reconstruction were democratic self-government, economic stability, and peaceful Japanese co-existence with the community of nations. The United States allowed Japan to keep its emperor — Hirohito — after the war. However, Hirohito had to renounce his divinity and publicly support Japan's new constitution.

After the defeat of Japan in World War II, the United States led the Allies in the occupation and rehabilitation of the Japanese state. ... In September, 1945, General Douglas MacArthur took charge of the Supreme Command of Allied Powers (SCAP) and began the work of rebuilding Japan
