When most people think of Japanese history, their first thought is the samurai, which are usually thought to only be male. Many know little about female samurai, or deny that they exist in any form other than modern entertainment like Japanese anime. Referred to as onna bugeisha, female samurai did in fact exist, and some are highly revered in Japanese history and culture, contradicting the view of Japan's historically strict gender roles. However, they remain relatively unknown to the Western world. Due to this lack of knowledge by the general public, my poster presentation looks at the few women we do know about and how they impacted Japanese history. It will also give some general facts about the onna bugeisha, including what weapons they typically used compared to male samurai and the training they underwent. The information that is presented will be from a variety of sources, many written recently.
