Kyōgoku Takakazu was killed in 1441 during the Kakitsu no Hen, a rebellion during which the "shōgun" Ashikaga Yoshinori was assassinated by disaffected vassals at a dinner banquet hosted by Akamatsu Mitsusuke, one of the vassals who had been stripped of his lands and titles. Kyōgoku Takakazu died defending the Shogun along with Ōuchi Mochiyo (1394–1441) head of the Ōuchi clan who died later of his wounds on 28 July 1441. Kyōgoku Takakazu died during the incident on 12 July 1441 as he was cut down by Mitsusuke soldiers.
