Final answer:
The United States shifted its focus in Japan from trying to reform the Japanese government and decentralize the country's economy to restoring Japan's industrial capabilities.
Step-by-step explanation:
The correct answer is a) Restoring Japan's industrial capabilities.
By 1948, the United States had shifted its focus in Japan from trying to reform the Japanese government and decentralize the country's economy to restoring Japan's industrial capabilities.
After World War II, the U.S. provided financial assistance and preferential access to U.S. markets to rebuild the Japanese economy, with the aim of countering the perceived communist threat in Asia. Japan's successful industrial model ultimately produced electronics and automobiles that dominated their sectors worldwide.
