After Puyi became Emperor of Manchukuo, Kawashima continued to play various roles and, for a time, was the mistress of Hayao Tada, the chief military advisor to Puyi. She formed an independent counterinsurgency cavalry force in 1932 made up of 3,000-5,000 former bandits to hunt down anti-Japanese guerrilla bands during the Pacification of Manchukuo, and was hailed in the Japanese newspapers as the Joan of Arc of Manchukuo. In 1933, she offered the unit to the Japanese Kwantung Army for Operation Nekka, but it was refused. The unit continued to exist under her command until sometime in the late 1930s.
