德川家齊
After Go-Mizunoo's death, his daughter Princess Mitsuko became a nun, and established another temple there, the "Ryinku-ji", in what later became the Middle Garden. The gardens and buildings then fell into disrepair, with some of the buildings either being destroyed or removed. During the rule of Tokugawa Ienari, the 11th Tokugawa "shōgun", the Shūgaku-in was thoroughly renovated.
