Life
Princess Yoshiko was born in 1632 to Emperor Go-Mizunoo and his wife, Tokugawa Masako. Yoshiko was Masako's last surviving child, and so following her birth Masako adopted Prince Tsuguhito (later Emperor Go-Kōmyō) who became the heir of their sister, Empress Meishō.
In 1644 she was promoted to the rank of Imperial Princess, and the following year wed Nijō Mitsuhira.
Mitsuhira was himself related to Yoshiko through his mother, Princess Sadako, daughter of Emperor Go-Yōzei.
From this marriage came a daughter, Ryūsōin, who married Tokugawa Tsunashige. However in 1669 Ryūsōin died only aged 22.
Following the death of her husband in 1682, Yoshiko became a nun and died in 1696.
