10.2 Economic growth and technological advancements

Japan's postwar economic miracle transformed the nation from war-torn ruins to a global powerhouse. American occupation reforms, export-oriented strategies, and government-business cooperation fueled rapid growth. High savings rates, an educated workforce, and technological adaptation propelled Japan's rise.

This economic boom revolutionized Japanese society and industry. While living standards soared and Japan dominated global markets in electronics and automobiles, rapid growth also brought challenges. Urbanization, environmental issues, and changing family structures emerged as consequences of this dramatic transformation.
