History of use
Recent research by Mie University historians Yūji Yamada, Katsuya Yoshimaru, and others indicates that there are no historical records of the existence of female ninja who conducted reconnaissance and subversive activities in the same manner as their male counterparts.
According to Yoshimaru, kunoichi came to mean "female ninja" in the creative works largely due to the influence of Futaro Yamada's ''Ninpōchō'' series.
During the Edo period, kunoichi was used as a cant term to refer to a woman and had no meaning for a female ninja. However, the term has very few examples of usage, most likely because the writing style at the time was not composed of the three strokes attributed to kunoichi.

. According to this document, the main function of the kunoichi was espionage, finding functions in enemy house services, to gather knowledge, gain trust or listen to conversations.
[ Seiko Fujita, ''From Ninjutsu to Spy Warfare'' (忍術からスパイ戦へ). Higashi Shisha, 1942. pp 83.] This "technique to use a female" was employed for infiltration purposes when it was difficult for a man to infiltrate.
There is a technique in which a kunoichi uses a double-bottomed wooden chest to infiltrate a person into a building by telling the wife of the house that she is retrieving a wooden chest. Both of these techniques however are described as "techniques through the usage of a woman".
Seiko Fujita considers these techniques to be evidence of female ninja,
while Yoshimaru and Yamada consider female ninja not to have existed.
