豊臣秀頼
In 1603, Nene attended Toyotomi Hideyori and Senhime's wedding. In 1606 with the help of Tokugawa Ieyasu, she established a Buddhist temple Kōdai-ji in Kyoto, to which she moved. It became the burial area for her husband, his mother, and later Toyotomi Hideyori. During the contest between Toyotomi Hideyori and Tokugawa Ieyasu for supremacy (Siege of Osaka), Kōdai-in took the side of Ieyasu.
