Published January 25, 2025 | Shokuho Women's History Team | 10 min read

While popular culture often portrays feudal Japan as a exclusively male-dominated warrior society, the reality was far more complex. Throughout the Sengoku period, women played crucial roles as warriors, military leaders, and political powers behind the throne. The onna-bugeisha (female martial artists) and female daimyo of this era demonstrated exceptional courage, strategic thinking, and martial prowess that rivaled their male counterparts. Their stories reveal a more complete picture of Japanese history and the diverse paths to power and influence available to exceptional women. These remarkable figures are represented in the Shokuho mod for Mount & Blade II: Bannerlord, showcasing the authentic diversity of leadership in Sengoku Japan.

The Tradition of Women Warriors in Japan

The concept of women warriors in Japan predates the Sengoku period by centuries, rooted in both practical necessity and cultural acceptance of women's martial capabilities under specific circumstances.

Historical Precedents and Cultural Foundation

Japanese history includes numerous examples of women taking up arms in defense of family, honor, or territory. Unlike some other cultures, Japan had established precedents for women's martial participation that provided legitimacy for female warriors during the Sengoku era.

Cultural foundations included:

  • Defensive Traditions: Women expected to defend homes and castles when men were absent
  • Educational Systems: Martial training included in upper-class women's education
  • Religious Influences: Buddhist and Shinto traditions that didn't exclude women from martial pursuits
  • Literary Models: Stories of heroic women warriors in classical literature

The Naginata: Women's Weapon of Choice

The naginata became closely associated with women warriors, though historical evidence suggests both men and women used this versatile polearm. Its association with women may have developed because its techniques were particularly suitable for defending fixed positions like castles and homes.

Naginata advantages for women included:

  • Reach advantage compensating for potential physical differences
  • Sweeping techniques effective against multiple opponents
  • Defensive capabilities suitable for protecting specific locations
  • Cultural acceptance as an appropriate weapon for women
Training and Education: Many samurai families ensured their daughters received martial training, recognizing that women might need to defend the family honor and property. This practical approach created a foundation for women's military participation throughout Japanese history.
