Yasutaka was an uncle to Togashi Masachika and had served as shugo of Kaga prior to the latter. In 1487 he lent his support to the Ikko uprising against Masachika from Kyoto and was allowed to act as nominal shugo of Kaga. Nonetheless he did not actually go to live in the province until 1493, when he was forced to flee the capital by Hosokawa Masamoto. He attempted to aid ousted shôgun Ashikaga Yoshitane in his bid to reclaim the capital, and clashed with the Asakura on a number of occasions to this end (1494, 1504).
