How did World War 2 affect the Japanese economy?

Answer 1

Although the Japanese economy was severely damaged and dislocated by the bombing/blockade during WW2, important foundations were laid for postwar growth. The heavy industry sector expanded at the expense of light industry, inflation destroyed the fortunes of the zaibatsu magnates and helped create an equitable society and the industries and engineers that had made machine guns, aeroplanes and optical sights during the war converted to the production of sewing machines, motor vehicles and cameras after the conflict, fueling postwar economic growth.
