Токугава Иэясу
Imagawa Ujizane succeeded to family headship after Yoshimoto's death, but the Imagawa clan fell from power. Ujizane was later summoned by Tokugawa Ieyasu and became a "kōke" in the administration of the Tokugawa clan. Yoshimoto's niece was Lady Tsukiyama, the wife of Tokugawa Ieyasu.
