What was the u.s role in rebuilding japan?

Question:

Answer:

If you are asking about US occupation of Japan after WWII, it was very successful for the most part.

The US had four major programs for the reform of Japan.
1. Demilitarization of Japan.
2. Educational reform from militarism to democracy.
3. Dissolution of huge financial organizations that had close relations with Japanese militarism during the war.
4. Land reform, which means releasing farm land all over the nation from a limited numbers of land owners to individual farmers.

All of them went successfully until the Korean War broke out in 1950. US occupation policy of Japan drastically changed from demilitarization to remaking Japan as a strong fort against communist invasion in East Asia. The advent of communist PRC in 1949 and USSR presence in this region made the US realize Japan's geopolitical importance for the national interest of the US in Asia Pacific at large.

From Japanese point of view, the Korean War was a gift from heaven for the reconstruction of our economy. Because, Japan was greately benefited by the "special procurement" from the US during the war. Without the Korean War, reconstruction of Japanese industry and economy would have been much delayed.
