At the time of her marriage, the eldest daughter was 16 and her husband Kujō Hisatsune (chancellor, 1501–13) was 28. It would seem to have been a formal marriage, for a bridal palanquin was sent for her from the Kujō house, to where she went in a ceremonial manner. The son she bore to Hisatsune, called Tanemichi, later became chancellor (1533–34), and she was given the title Kita no mandokoro. In all, she bore three sons and three daughters.
Sanjōnishi Yasuko, Sanetaka's eldest daughter, who was married to Kujō Hisatsune (1468–1530) in 1495. The marriage secured an immediate elevation in social circumstances, since the Kujō, as one of the select five Regent Houses (gosekke), were of a higher status than the Sanjōnishi. Yasuko was now the wife of a future regent, and any male heirs she bore would likely occupy the position in the future; indeed, her son Kujō Tanemichi (1507–94) eventually became regent in 1533.
