In the First Battle of Azukizaka (小豆坂の戦い, Azukizaka no tatakai) Oda Nobuhide defeated Imagawa Yoshimoto,[1] setting the stage for his son, Oda Nobunaga, to become one of Japan's greatest warlords.

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.

Nobuhide was joined by his brothers Nobuyasu, Nobumitsu, and Nobuzane.

The battle was quickly won by the Oda side, with credit given to seven Samurai, known as the "Seven Spears of Azukizaka".

Kawajiri Hidetaka fought with Yuhara (由原), who was the forerunner of the Imagawa clan, and defeated him at the battle's end.
