Tomoe (巴) is the Japanese word for the comma-shaped magatama swirl. **Tomoe Gozen (c. 1157-1247)** was the **onna-musha (woman warrior)** who fought alongside Minamoto no Yoshinaka during the **Genpei War (1180-1185)**. **The Tale of the Heike describes her as 'a thousand warriors' worth' — riding into battle in armor, taking heads, and surviving the war**. The most famous female samurai in Japanese history.
Featured throughout Japanese drama, film, and the manga *Drifters*.
Tomoe reduces to four — the number of onna-musha.
