The United States occupation of Japan (1945-52) resulted in the rebuilding of the nation and the creation of a democratic state. United States assistance totaled about US$1.9 billion during the occupation, or about 15% of the nation's imports and 4% of GNP in that period. About 59% of this aid was in the form of food, 15% in industrial materials, and 12% in transportation equipment. United States grant assistance, however, tapered off quickly in the mid-1950s. United States military procurement from Japan peaked at a level equivalent to 7% of Japan's GNP in 1953 and fell below 1% after 1960. A variety of United States-sponsored measures during the occupation, such as land reform, contributed to the economy's later performance by increasing competition. In particular, the postwar purge of industrial leaders allowed new talent to rise in the management of the nation's rebuilt industries. Finally, the economy benefited from foreign trade because it was able to expand exports rapidly enough to pay for imports of equipment and technology without falling into debt, as had a number of developing nations in the 1980s.
