大陸打通作戦
Initially tasked primarily with border patrol of Manchukuo's western frontier with the Soviet Union, from April 1944, it participated in Operation Ichi-Go in northern China against the National Revolutionary Army of the Republic of China. The two primary goals of Ichi-go were to open a land route to French Indochina, and capture air bases in southeast China from which American bombers were attacking the Japanese homeland and shipping.
