First Battle of Azukizaka
In response to Oda moves into Western Mikawa, Imagawa Yoshimoto moved forces into Ikutahara in the 8th month of 1542. Oda Nobuhide responded to this by leaving his position at Anjô castle and crossing the Yahagi river taking up a position at Kamiwada, and in the 10th month, engaged in battle at Azukizaka, Southeast of Okazaki castle. The Imagawa vanguard was led by a warrior by the name of Yuhara from Suruga province, and Nobuhide was joined by his brothers Nobuyasu, Nobumitsu, and Nobuzane. The battle was quickly won by Oda side, with credit given to seven Samurai, known as the Seven Spears of Azukizaka.
