Imagawa Yoshimoto
Kazutada was born in Owari Province in central Japan. He started out as a page to Oda Nobunaga and fought as a pikeman against Imagawa Yoshimoto during the Battle of Okehazama in 1560. During the battle, Kazutada was the first of Nobunaga's men to mount a personal attack on Imagawa Yoshimoto, but received a sword cut across the legs and was about to be killed when Mōri Yoshikatsu came to his rescue and killed Yoshimoto. He was rewarded by Nobunaga for his role in the victory, but little is known about his subsequent service.
