Imperial Rule Assistance Association

The Imperial Rule Assistance Association (Japanese: 大政翼贊會/大政翼賛会, Hepburn: Taisei Yokusankai), or Imperial Aid Association, was the Empire of Japan's ruling political organization during much of the Second Sino-Japanese War and World War II.

The associated was created by Prime Minister Fumimaro Konoe by a merger of the contemporary political parties Rikken Seiyūkai, Rikken Minseitō, Kokumin Dōmei, and Shakai Taishūtō on 12 October 1940. It was formed to promote the goals of his Shintaisei ("New Order") movement. It evolved into a statist, para-fascist ruling political party which aimed at removing sectionalism and factionalism from politics and economics in Japan, creating a totalitarian one-party state in order to maximize the efficiency of Japan's total war effort against China and later the Allies.

When the organization was launched officially, Konoe was hailed as a "political savior" of a nation in chaos; however, internal divisions soon appeared. After the 1942 Japanese general election, all members of Diet were required to join the Imperial Rule Assistance Political Association. The Imperial Rule Assistance Association was formally dissolved on 13 June 1945, around three months before the end of World War II in the Pacific Theater.
