The office of Inspectorate General of Military Training was established 20 January 1898, to provide a unified command for the Imperial Japanese Army Academy, and the various specialized weaponry and technical training schools, and the military preparatory schools located in various locations around the country.
It also had broad powers of oversight over Army logistics, transportation, and support issues.
Due to its political power, the post was highly sought after by Army senior leadership, and a factional dispute over succession was one of the triggering factors of the February 26 Incident.
The post was abolished with the dissolution of the Imperial Japanese Army after the surrender of Japan at the end of World War II.
Also from 1941, a 2nd Bureau was added to the organizational structure, to specialize in armored car training.
