The Ki-10 was deployed in Manchuria and in the initial campaigns of the Second Sino-Japanese War in northern China. It proved an excellent dogfighter against the Chinese air force, including at the Battle of Wuhan. However, by the time of the Nomonhan Incident in 1939, against the forces of the USSR, it was largely obsolete. At the beginning of the Pacific War, the Ki-10 was retired to training and secondary missions, but later returned to front-line service, performing short-range patrol and reconnaissance missions in Japan proper and China in January-February 1942.
