Ise Sadatsugu

Ise Sadatsugu was a warrior of the Kamakura and Muromachi periods who served the Ashikaga shoguns Takauji, Yoshiakira and Yoshimitsu. By 1361 he had taken Buddhist vows as Shōzen while remaining Yoshiakira's mōshitsugi usher.

After the Kōryaku coup of 1379 he became shitsuji of the shogunate's Mandokoro, holding the office until his death in 1391 and beginning the Ise family's hereditary hold on it. Yoshimitsu was born at his residence.
