Japan faced a severe economic challenge in the mid-1970s. The world oil crisis in 1973 shocked an economy that had become virtually dependent on foreign petroleum. Japan experienced its first postwar decline in industrial production, together with severe price inflation. The recovery that followed the first oil crisis revived the optimism of most business leaders, but the maintenance of industrial growth in the face of high energy costs required shifts in the industrial structure.

Changing price conditions favored conservation and alternative sources of industrial energy. Although the investment costs were high, many energy-intensive industries successfully reduced their dependence on oil during the late 1970s and 1980s and enhanced their productivity. Advances in microcircuitry and semiconductors in the late 1970s and 1980s led to new growth industries in consumer electronics and computers, and to higher productivity in pre-established industries. The net result of these adjustments was to increase the energy efficiency of manufacturing and to expand so-called knowledge-intensive industries. The service industries expanded in an increasingly postindustrial economy.

Structural economic changes, however, were unable to check the slowing of economic growth as the economy matured in the late 1970s and 1980s, attaining annual growth rates at only 4 to 6%. But these rates were remarkable in a world of expensive petroleum and in a nation of few domestic resources. Japan's average growth rate of 5% in the late 1980s, for example, was far higher than the 3.8% growth rate of the United States. Despite more petroleum price increases in 1979, the strength of the Japanese economy was apparent. It expanded without the double-digit inflation that afflicted other industrial nations (and that had bothered Japan itself after the first oil crisis in 1973). Japan experienced slower growth in the mid-1980s, but its demand-sustained economic boom of the late 1980s revived many troubled industries.
