The Army Ministry of Japan (陸軍省 Rikugun-shō), more popularly known as the Ministry of War of Japan, was cabinet-level ministry in the Empire of Japan charged with the administrative affairs of the Imperial Japanese Army (IJA). It existed from 1872 to 1945.

History

The Army Ministry was created in April 1872, along with the Navy Ministry, to replace the Ministry of the Military (兵部省 Hyōbushō) of the early Meiji government.

Initially, the Army Ministry was in charge of both administration and operational command of the Imperial Japanese Army. However, with the creation of the Imperial Japanese Army General Staff in December 1878, it was left with only administrative functions. Its primary role was to secure the army budget, weapons procurement, personnel, relations with the Diet of Japan and the Cabinet and broad matters of military policy.

The post of Army Minister was politically powerful. Although a member of the Cabinet after the establishment of the cabinet system of government in 1885, the Army Minister was answerable directly to the Emperor (the commander-in-chief of all Japanese armed forces under the Meiji Constitution) and not the Prime Minister.

From the time of its creation, the post of Army Minister was usually filled by an active-duty general in the Imperial Japanese Army. This practice was made into law under the "Military Ministers to be Active-Duty Officers Law" (軍部大臣現役武官制 Gumbu daijin gen'eki bukan sei) in 1900 by Prime Minister Yamagata Aritomo to curb the influence of political parties into military affairs. Abolished in 1913 under the administration of Yamamoto Gonnohyōe, the law was revived again in 1936 at the insistence of the Army General Staff by Prime Minister Hirota Kōki. At the same time, the Imperial Japanese Army prohibited its generals from accepting political offices except by permission from the Army high command. Taken together, these arrangements gave the Imperial Japanese Army an effective, legal right to nominate (or refuse to nominate) the Army Minister. The ability of the Imperial Japanese Army to refuse to nominate an Army Minister gave it effective veto power over the formation (or continuation) of any civilian administration, and was a key factor in the erosion of representative democracy and the rise of Japanese militarism.

After 1937, both the Army Minister and the Chief of the Army General Staff were members of the Imperial General Headquarters.

With the defeat of the Empire of Japan in World War II, the Army Ministry was abolished together with the Imperial Japanese Army by the American occupation authorities in November 1945 and was not revived in the post-war Constitution of Japan.
