Changes

In September 1945, General Douglas MacArthur took charge of the Supreme Command of Allied Powers (SCAP) and began the work of rebuilding Japan. Although Great Britain, the Soviet Union, and the Republic of China had an advisory role as part of an “Allied Council,” MacArthur had the final authority to make all decisions. The occupation of Japan can be divided into three phases: the initial effort to punish and reform Japan, the work to revive the Japanese economy, and the conclusion of a formal peace treaty and alliance.

The first phase, roughly from the end of the war in 1945 through 1947, involved the most fundamental changes for the Japanese Government and society. The Allies punished Japan for its past militarism and expansion by convening war crimes trials in Tokyo. At the same time, SCAP dismantled the Japanese Army and banned former military officers from taking roles of political leadership in the new government. In the economic field, SCAP introduced land reform, designed to benefit the majority tenant farmers and reduce the power of rich landowners, many of whom had advocated for war and supported Japanese expansionism in the 1930s.
