Tango Province
While at the court in 1009, she married Fujiwara no Yasumasa (958-1036), a military commander under Michinaga famous for his bravery, and left the court to accompany him to his charge in Tango Province. She outlived her daughter Koshikibu no Naishi, but the year of her death is unknown. The last Imperial correspondence from her was a poem written in 1027. The Eiga Monogatari includes this poem, which accompanied Yasumasa's offering of jewels for a Buddha figure "made in memory of the Empress Dowager Yoshiko."
