Recalling a pivotal moment in Japanese history what do you think about? The Army Ministry or Rikugun-shō played a crucial role in the Empire of Japan. It existed from 1872 to 1945. The Army Ministry was also known as the Ministry of War. It was the cabinet-level ministry. It handled the administrative affairs of the Imperial Japanese Army.
Initially the Army Ministry managed administration and operations. The Imperial Japanese Army General Staff Office was created in December 1878. This left the Ministry with only administrative roles. It secured the army budget. It oversaw weapons procurement. Personnel matters fell under its purview. It maintained relations with the National Diet and the Cabinet. It addressed broad matters of military policy.
The Army Minister was politically powerful. He was a member of the Cabinet after 1885. He answered directly to the Emperor. The Emperor was commander-in-chief. This was under the Meiji Constitution. The Army Minister was not answerable to the Prime Minister.
Active-duty generals usually filled the post of Army Minister. This became law in 1900. Prime Minister Yamagata Aritomo wanted to curb political party influence. The “Military Ministers to be Active-Duty Officers Law” formalized this. Abolished in 1913 it was revived in 1936. Prime Minister Hirota Kōki insisted on its return. The Army General Staff pushed for it. The Imperial Japanese Army then forbade generals from accepting political posts. Permission from Imperial General Headquarters was required.
These arrangements gave the Army a legal right. It could nominate or refuse to nominate the Army Minister. This gave it veto power. It could influence any civilian administration. This was key in the erosion of democracy. It contributed to the rise of Japanese militarism.
After 1937 the Army Minister was a member of the Imperial General Headquarters. So was the Chief of the Army General Staff.
The Allied occupation authorities abolished the Army Ministry in November 1945. This happened after Japan’s surrender in World War II. The post-war Constitution of Japan did not revive it.
The Army Ministry had various bureaus. These included the Military Affairs Bureau. There was also a Personnel Bureau and an Ordnance Bureau. Other bureaus included Development Military Administration Intendance Medical Judge and Warhorse. External bureaus existed too. These included the Army Fortification Department. There was an Army Transport Department and more.
The Army Ministry and Imperial General Headquarters were in Ichigaya Heights. This area is now part of Shinjuku Tokyo.
Many individuals served as Army Minister. Ōyama Iwao held the position multiple times. Katsura Tarō also served. Other ministers included Terauchi Masatake and Tanaka Giichi. Hideki Tojo also held the position.
The Army Ministry remains a significant part of history. It shaped Japan’s military and political landscape.
