Aide-de-camp to the Emperor of Japan

In Japan, the aide-de-camp to the Emperor (侍従武官) is a special military official whose primary duties are to report military affairs to the Emperor and act as a close attendant (chamberlain). From 1896 through to 1945, a small number of army and naval aides-de-camp were supplied to the Emperor due to his increased status and the risks to him during wartime.

Background
An excerpt from the 113th Imperial decree of Meiji-29 (1896) (明治29年勅令第113号):
 * Aides-de-camp to the Emperor will perform attendant duties and will relay to him military matters and orders, be present at military reviews [in his name] and accompanying him to formal ceremonies and interviews.

Both Prime Minister Kantarō Suzuki (鈴木貫太郎) and Anami Korechika (阿南惟幾), army ministers at the end of the war, are said to have contributed to the Potsdam Declaration acceptance by means of their responsibilities to Emperor Showa as the grand chamberlain and aide-de-camp to the Emperor in 1929 (Showa-4).

Moreover, to the Crown Prince, the Imperial Family, and the mediatized Korean royal family (Oukouzoku (王公族), the former Korean imperial family), aides-de-camp were also provided. The military officers serving the Oukouzoku wore silver aiguillettes over their uniform.
