Onna-bugeisha is a Japanese term that refers to women who were warriors. These women were very brave and strong and were trained in the art of fighting with weapons like swords, spears, and bows and arrows.
Back in Japan a long time ago, men were usually the ones who did the fighting and women were supposed to stay home and take care of things there. However, there were some women who didn't want to just sit at home and wanted to fight to protect their families and their homes.
The onna-bugeisha were very special because they could fight just as well as the men. They were taught by other expert women in fighting techniques and they would wear armor just like the men did. They were also very skilled in horse riding and swimming, which helped them become even better fighters.
Some of the most famous onna-bugeisha were Tomoe Gozen, Nakano Takeko and Hōjō Masako. These women were so good at fighting that they became legends and were praised by many people.
Nowadays, the onna-bugeisha are still remembered and respected in Japan for their bravery and fighting skills.
