Post-occupation Japan

Post-occupation Japan is the period in Japanese history which started after the Allied occupation of Japan ended in 1952. Japan has established itself as a global economic and political power.

The Allied occupation ended on April 28, 1952, when the terms of the Treaty of San Francisco went into effect. By the terms of the treaty, Japan regained its sovereignty, but lost many of its possessions from before World War II, including Korea, Taiwan and Sakhalin. It also lost control over a number of small islands in the Pacific which it administered as League of Nations Mandates, such as the Marianas and the Marshalls. The new treaty also gave Japan the freedom to engage in international defense blocs. Japan did this on the same day it signed the San Francisco Treaty: Japanese Prime Minister Shigeru Yoshida and U.S. President Harry S. Truman signed a document that allowed the United States Armed Forces to continue their use of bases in Japan.

Even before Japan regained full sovereignty, the government had rehabilitated nearly 80,000 people who had been purged, many of whom returned to their former political and government positions. A debate over limitations on military spending and the sovereignty of the emperor ensued, contributing to the great reduction in the Liberal Party's majority in the first postoccupation elections (October 1952). After several reorganizations of the armed forces, in 1954 the Self-Defense Forces were established under a civilian director. Cold War realities and the hot war in nearby Korea also contributed significantly to the United States-influenced economic redevelopment, the suppression of communism, and the discouragement of organized labor in Japan during this period.
