The 1573 Siege of Hikida Castle (疋壇城の戦い, Hikida-jō no Tatakai) was one of many battles the warlord Oda Nobunaga fought against the Azai and Asakura clans during Japan's Sengoku period.
These two families were among the staunchest opponents of Nobunaga's attempts to seize land and power for himself.
In respond, Asakura Yoshikage, led a 20,000 forces to relieve and reinforce the Azai garrison.
Later, when Yoshikage came under attack by Nobunaga's army, he sought refuge in Hikida Castle, and came under siege himself.
Later, Oda Nobunaga's forces advance to Echizen and attacked Ichijodani castle in September 1573, devastating the Asakura clan.
