Ashikaga Yoshiaki
After the capture of Kyoto in 1568, Ashikaga Yoshiaki appointed Yoshikage regent and requested Asakura aid in driving Nobunaga out of the capital.  As a result, in 1570, Oda Nobunaga launched an invasion of Echizen. Due to Yoshikage’s lack of military skill, Oda's forces besieged Kanegasaki Castle (in modern-day Tsuruga city), opening the entire Asakura Domain to invasion.
