An onna-bugeisha () was a type of female warrior belonging to the Japanese upper class. Many wives, widows, daughters, and rebels answered the call of duty by engaging in battle, commonly alongside samurai men. They were members of the bushi (samurai) class in feudal Japan and were trained in the use of weapons to protect their household, family, and honour in times of war. They also represented a divergence from the traditional 'housewife' role of the Japanese woman. They are sometimes referred to as female samurai. Significant icons such as Empress Jingu, Tomoe Gozen, Nakano Takeko, and Hj Masako are famous examples of onna bugeisha.
