1905 After the defeat of the Russo-Japanese War, Russia transferred the lease rights of "Kanto County" (southern Liaoning Province of China) and Nanman Railway to Japan according to the Portsmouth Peace Treaty.
In order to safeguard its own colonial interests, Japan sent two divisions and 40,000-strong corps to "Kanto County" and Nanman Railway, and set up the Kanto Governor's Office. The following year, the Governor's Office was changed to the Governor's Office, and the War Department was set up to administer 1 Army Division, six independent garrison battalions, Lushun Heavy Artillery Battalion and Gendarmerie.
