Answer: Yes, I think limits on the Japanese military helped the Japanese economy.
The Japanese economic miracle is known as Japan's record period of economic growth between the post-World War II era to the end of the Cold War. During the economic boom, Japan rapidly became the world's second largest economy (after the United States). By the 1990s, Japan's demographics began stagnating and the workforce was no longer expanding as it did in the previous decades, despite per-worker productivity remaining high. This economic miracle was the result of post-World War II Japan and West Germany benefitting from the Cold War. The American government reformed Japanese society during the occupation of Japan, making political, economic and civic changes. It occurred chiefly due to the economic interventionism of the Japanese government and partly due to the aid and assistance of the U.S. aid to Asia.
