Kurôjurô at first served Oda Nobuhide of Owari province. When Nobuhide died in 1551, Kurôjurô joined Imagawa Yoshimoto and moved his household to Nakamura, in Suruga province. Having raised an army he marched back to Owari and clashed with Oda Nobunaga at Akatsuka in the 4th month of 1553. Although Kurôjurô's army outnumbered Nobunaga's by nearly two to one (1,500 vs. 800), the battle was considered a draw. Kurôjurô retreated after exchanging captured horses and men with Nobunaga.
