In 1947, Deming was involved in early planning for the 1951 Japanese Census. The Allied powers were occupying Japan, and he was asked by the United States Department of the Army to assist with the census. He was brought over at the behest of General Douglas MacArthur, who grew frustrated at being unable to complete so much as a phone call without the line going dead due to Japan's shattered postwar economy. While in Japan, his expertise in quality-control techniques, combined with his involvement in Japanese society, brought him an invitation from the Union of Japanese Scientists and Engineers (JUSE).
