Masako (政子) combines the Japanese masa (correct, government) and ko (child). **Hojo Masako (1156-1225)** was the wife of Minamoto no Yoritomo, the first Shogun of Japan. **After her husband's death, she took Buddhist vows but continued to wield supreme political power as ama-shogun ("the Nun Shogun")** through her father, brother, and sons. **Effectively the first female ruler of Japan in the warrior era.**
Featured throughout *Azuma Kagami* and Japanese historical drama.
Masako reduces to seven — the number of Japan's Nun Shogun.
