Japan: Surrender and Occupation

Surrender and Occupation

The Japanese surrender at the end of World War II was unconditional, but the terms for Allied treatment of the conquered power had been laid down at the Potsdam Conference. The empire was dissolved, and Japan was deprived of all territories it had seized by force. The Japanese Empire at its height had included the southern half of Sakhalin, the Kuril Islands, the Ryukyu Islands, Taiwan, the Pescadores, Korea, the Bonin Islands, the Kwantung protectorate in Manchuria, and the island groups held as mandates from the League of Nations (the Caroline Islands, Marshall Islands, and Mariana Islands (see Northern Mariana Islands). In the early years of the war, Japan had conquered vast new territories, including a large part of China, SE Asia, the Philippines, and the Dutch East Indies. With defeat, Japan was reduced to its size before the imperialist adventure began.

The country was demilitarized, and steps were taken to bring forth “a peacefully inclined and responsible government.” Industry was to be adequate for peacetime needs, but war-potential industries were forbidden. Until these conditions were fulfilled Japan was to be under Allied military occupation. The occupation began immediately under the command of Gen. Douglas MacArthur. A Far Eastern Commission, representing 11 Allied nations and an Allied council in Tokyo, was to supervise general policy. The commission, however, suffered from the rising tension between the USSR and the Western nations and did not function effectively, leaving the U.S. occupation forces in virtual control.

The occupation force controlled Japan through the existing machinery of Japanese government. A new constitution was adopted in 1946 and went into effect in 1947; the emperor publicly disclaimed his divinity. The general conservative trend in politics was tempered by the elections of 1947, which made the Social Democratic party headed by Tetsu Katayama the dominant force in a two-party coalition government. In 1948 the Social Democrats slipped to a secondary position in the coalition, and in 1949 they lost power completely when the conservatives took full charge under Shigeru Yoshida.

Many of the militarist leaders and generals were tried as war criminals and in 1948 many were convicted and executed, and an attempt was made to break up the zaibatsu. Economic revival proceeded slowly with much unemployment and a low level of production, which improved only gradually. In 1949, however, MacArthur loosened the bonds of military government, and many responsibilities were restored to local authorities. At San Francisco in Sept., 1951, a peace treaty was signed between Japan and most of its opponents in World War II. India and Burma (Myanmar) refused to attend the conference, and the USSR, Czechoslovakia, and Poland refused to sign the treaty. It nevertheless went into effect on Apr. 28, 1952, and Japan again assumed full sovereignty.
