For five years after the war in the Pacific, J apan was governed by an Allied administration under the command of U.S. General Douglas MacArthur. The occupation regime, which consisted of the Far Eastern Commission in Washington, D.C., and the four-power Allied Council in Tokyo, was dominated by the United States, although the country was technically administered by a new Japanese government. As commander of the occupation administration, MacArthur was responsible for demilitarizing Japanese society, destroying the Japanese war machine, trying Japanese civilian and military officials charged with war crimes, and laying the foundations of postwar Japanese society. During the war, senior U.S. officials had discussed whether to insist on the abdication of the emperor as the symbol of Japanese imperial expansion. During the summer of 1945, the United States rejected a Japanese request to guarantee that the position of the emperor would be retained in any future peace settlement and reiterated its demand for unconditional surrender. After the war, however, the United States agreed to the retention of the emperor after he agreed publicly to renounce his divinity (see the box on p. 294). Although many historians have suggested that Emperor Hirohito opposed the war policy of his senior advisers, some recent studies have contended that he fully supported it. Under MacArthurís firm tutelage, Japanese society was remodeled along Western lines. The centerpiece of occupation policy was the promulgation of a new constitution to replace the Meiji Constitution of 1889. The new charter, which was drafted by U.S. planners and imposed on the Japanese despite their objections to some of its provisions, was designed to transform Japan into a peaceful and pluralistic society that would no longer be capable of waging offensive war. The constitution specifically renounced war as a national policy, and Japan unilaterally agreed to maintain armed forces only sufficient for selfdefense. Perhaps most important, the constitution established a parliamentary form of government based on a bicameral legislature, an independent judiciary, and a universal franchise; it also reduced the power of the emperor and guaranteed human rights. But more than a written constitution was needed to demilitarize Japan and place it on a new course. Like the Meiji leaders in the late nineteenth century, occupation administrators wished to transform Japanese social institutions and hoped their policies would be accepted by the Japanese people as readily as those of the Meiji period had been. The Meiji reforms, however, had been crafted to reflect native traditions and had set Japan on a path quite different from that of the modern West. Some Japanese observers believed that a fundamental reversal of trends begun with the Meiji Restoration would be needed before Japan would be ready to adopt the Western capitalist, democratic model. One of the sturdy pillars of Japanese militarism had been the giant business cartels, known as zaibatsu. Allied policy was designed to break up the zaibatsu into smaller units in the belief that corporate concentration, in Japan as in the United States, not only hindered competition but was inherently undemocratic and conducive to political authoritarianism. Occupation planners also intended to promote the formation of independent labor unions, to lessen the power of the state over the economy, and to provide a mouthpiece for downtrodden Japanese workers. Economic inequality in rural areas was to be reduced by a comprehensive land reform program that would turn the land over to the people who farmed it. Finally, the educational system was to be remodeled along American lines so that it would turn out independent individuals rather than automatons subject to manipulation by the state. The Allied program was an ambitious and even audacious plan to remake Japanese society and has been justly praised for its clear-sighted vision and altruistic motives. Parts of the program, such as the constitution, the land reform program, and the educational system, succeeded brilliantly. But as other concerns began to intervene, changes or compromises were made that were not always successful. In particular, with the rise of Cold War sentiment in the United States in the late 1940s, the goal of decentralizing the Japanese economy gave way to the desire to make Japan a key partner in the effort to defend East Asia against international communism. Convinced of the need to promote economic recovery in Japan, U.S. policymakers began to show more tolerance for the zaibatsu. Concerned at growing radicalism within the new labor movement, where left-wing elements were gaining strength, U.S. occupation authorities placed less emphasis on the independence of the labor unions. Cold War concerns also affected U.S. foreign relations with Japan. On September 8, 1951, the United States and other former belligerent nations signed a peace treaty restoring Japanese independence. In turn, Japan renounced any claim to such former colonies or territories as Taiwan (which had been returned to the Republic of China), Korea (which, after a period of joint Soviet and U.S. occupation, had become two independent states), and southern Sakhalin and the Kurile Islands (which had been ceded to the Soviet Union). The Soviet Union refused to sign the treaty on the grounds that it had not been permitted to play an active role in the occupation. On the same day, the Japanese and Americans signed a defensive alliance and agreed that the United States could maintain military bases on the Japanese islands. Japan was now formally independent, but in a new dependency relationship with the United States.
