In 1573, Oda Nobunaga laid siege to the Azai clan's Sawayama Castle, which was held by Kazumasa. The castle fell. In response, Azai Nagamasa took Kazumasa's elderly mother, who he held hostage in Odani Castle, to the execution grounds for death. Kazumasa became enraged to Nagamasa, then he defected to Nobunaga and became a vassal of the Oda clan, but later he became a priest in Mount Kōya.[1]
