The Battle of Akatsuka took place in 1552 which Nobunaga fought the Yamaguchi near Narumi Castle. The castle was built 1394 by Yasuhara Munenori. Narumi Castle was also known as Negoya Castle. Located in modern day Nagoya City, Midori-ku, the castle played a key role in 1560 during the Battle of Okehazama. The Yamaguchi were old retainers of Oda Nobuhide. When Nobuhide died in 1551, the Yamaguchi rebelled against young Nobunaga. What the Yamaguchi did not know and it was a mistake, they underestimated Nobunaga.
Fighting began in the middle of April of 1552. The Yamaguchi were led by Noritsugu and his son Kurojiro. The Yamaguchi also built Fort Kasadera and Nakamura in support of Narumi Castle. They also had support from the Imagawa of Suruga. Suruga men included, Kazurayama, Okabe, Iio, Muira, and the Azai. Nobunaga departed Nagoya Castle for war and he only had 800 men with him. As for the Yamaguchi, the had almost twice as much, 1,500. Fighting was heavy and violent. The end result was a draw. The big idiot was a tough nut to crack. Nobunaga knew how to fight with less. This was a great strength of his. For example, in 1561, he defeated the Saito in the Battle of Moribe with less men. Most of the time he came out on top. The Yamaguchi had to be in shock even with support from the outside. Still, they could not defeat Nobunaga. He would actually forgive the Yamaguchi in the future. It would only be a year later (1553) where Nobunaga would meet his father-in-law. The viper was about to soon find out that the big fool was a genius!
