Women of the Sengoku Era and Their Swords — Princesses, Consorts, and Armed Women

Sengoku-era Japan evokes bloody warrior battles, but the women of that era also had deep ties to swords. Women who left their names as wives, mothers, and daughters of famous warlords sometimes protected their lives with blades and joined combat to defend family and castle. This article explores Sengoku women's relationship with swords through historical examples.

Kaiken — Women's Self-Defense Blade

For samurai-class Sengoku women, kaiken were daily essentials. Kaiken are small daggers about 20 cm long, carried tucked in the kimono or obi. Their roles were multifaceted — not merely decorative but practical weapons, tools, and symbols.

Self-defense: In a warring age, women were always at risk of violence. Kaiken served to defend against armed soldiers or, to avoid captivity's shame, as means of ending one's own life. "Women defend themselves with kaiken" was not mere slogan but sometimes actual conduct.

Utility: Cutting hair, adjusting clothing, assisting with meals — kaiken saw daily use.

Symbolism: Kaiken grounded samurai women spiritually and were often among bridal goods from the natal home, maintaining identity in the marital household.

Naginata — The Samurai Woman's Combat Weapon

In Sengoku, naginata was an important martial art samurai women studied. As discussed in the sohei article, naginata combined long shaft with curved blade, enabling reach-based combat. Even physically weaker women could deliver powerful strikes using body weight and centrifugal force, making it well-suited to women.

Samurai daughters trained from childhood in naginata, acquiring "women's martial skill." This was no mere formality — numerous records document women taking up arms when castles faced fall.

Examples — Armed Sengoku Women

Sengoku history preserves records of women who took up weapons.

Ii Naotora

Ii Naotora, though a woman, inherited the Ii family and ruled the domain as "woman jitō." As portrayed in the NHK taiga drama, amidst Sengoku's upheaval she reportedly took up swords and naginata to fulfill her warrior duties.

Tachibana Ginchiyo

Tachibana Ginchiyo was the daughter of Tachibana Dosetsu, a Kyushu daimyo. Succeeding her father, she became a female castle lord. She is said to have armed her female retainers to defend Tachibanayama Castle, organizing "women's troops."

Tomoe Gozen

Tomoe Gozen lived in late Heian, but she was remembered as an aspirational figure for Sengoku samurai women. Kiso Yoshinaka's consort, she wielded naginata on battlefields and accomplished many feats of arms, becoming a model for later women warriors.

Myorin-ni

Myorin-ni married into a branch of the Otomo family of Bungo and fought to protect the house after her husband's death. She famously welcomed an enemy Shimazu force into a temple for a drinking banquet, then struck during their distraction to achieve victory. She exemplifies Sengoku women of cunning and courage.

Women Defending Castles

Records abound of women taking charge in castles while men were deployed. When castles came under siege, women formed the last defensive line, taking up weapons.

At the fall of Gassantoda Castle under the Amago clan, the women inside reportedly fought to the end with naginata. During Tokugawa Ieyasu's Odawara campaign, women in Hojo castles carried provisions and nursed wounded soldiers. Women's support roles, even without weapons, were essential to sustaining Sengoku warfare.

Marriage and Swords — Dowry Role

In Sengoku samurai marriages, swords were important dowry items. Tachi, katana, and kaiken passed down in the natal family were commonly brought to the marital home. More than mere gifts, they carried these meanings:

Displaying the natal family's rank and wealth. Inheriting heirloom swords showing the bride's lineage. Serving as spiritual support in the marital home. Providing "return gifts" should the marriage be dissolved.

In some prestigious samurai houses, specific swords were passed as dowries across generations, becoming parts of family history themselves.

Legacy of Sengoku Women's Sword Culture

The Edo peace ended women's battlefield opportunities. Yet the culture of samurai women carrying swords continued. Naginata became part of "fudo" — the way of womanhood — integral to samurai daughters' education, and from Meiji it continues as modern "naginata" martial art today.

Modern naginata is widely practiced by women as budo and sport, but its origins lie in Sengoku armed women. Remembering these women who defended their lives, families, and sometimes joined battle in the shadow of male-centered Sengoku history adds dimension to our understanding of Japanese sword history.

The pride and resolve embedded in a single kaiken or naginata — this, too, is an important chapter in Japanese sword culture.
