Kenji Doihara
After Tanaka was recalled to Japan, Kawashima continued to serve as a spy for the general Kenji Doihara. She undertook undercover missions in Manchuria, often in disguise, and was considered "strikingly attractive, with a dominating personality, almost a film-drama figure, half tom-boy and half heroine, and with a passion for dressing up as a male. She possibly did this in order to impress the men, or she may have done it in order to more easily fit into the tightly-knit guerrilla groups without attracting too much attention".
