Asakura Kagetada served Asakura Yoshikage as a member of the Asakura clan in Echizen Province. A descendant of Asakura Masakage, he used the family name Toba after the name of the area under his governance.
In 1568, Ashikaga Yoshiaki, the shōgun, visited the residence of their lord, Asakura Yoshikage. Kagetada’s father, Kagetomi, ranked seventh in order of the nineteen members of the clan who received Yoshiaki. After the demise of the Asakura clan at the hands of the Oda, Kagetada joined uprisings led by members of the Ikkō sect. In 1575, when Oda Nobunaga invaded Echizen for a second time, Kagetada and six hundred soldiers attempted to defend Toba Castle, but the castle was captured and the defenders crushed by Oda forces under the command of Shibata Katsuie and Niwa Nagahide. Kagetada himself, however, escaped to continue the resistance against the Oda.
Asakura Miyamasamaru, a survivor of the defeat to the Oda, sought help from Ashikaga Yoshiaki and the Mōri in Bingo Province in a bid to reconstitute the Asakura. In 1578, Yoshiaki and Mōri Terumoto encouraged him to install Kagetada as lord and revive the clan. At the time, the only member of the clan with a higher rank than Kagetada was Asakura Kageyoshi, located in Echigo Province under the protection of the Uesugi clan. Upon the death of Uesugi Kenshin, powerful leader of the Uesugi clan, Kageyoshi’s own plan to revive the clan through force unraveled. Meanwhile, Miyamasumaru’s scheme depended upon Kagetada, who was next in line among surviving members of the Asakura. However, Miyamasumaru could not easily contact Kagetada while Kagetada was outside of Echizen, and after losses by the Mōri in battles against the Oda across the Chūgoku Region, plans to revive the Asakura clan collapsed, after which Kagetada’s whereabouts became unknown.
