Onna-musha (女武者) is a term referring to female warriors in pre-modern Japan. These women fought in battle alongside samurai men. They were members of the bushi (warrior) 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 have an important presence in Japanese literature, with Tomoe Gozen and Hangaku Gozen as famous and influential examples representing onna-musha.

A warrior is a guardian specializing in combat or warfare, especially within the context of a tribal or clan-based warrior culture society that recognizes a separate warrior aristocracy, class, or caste.
