Akashi Kageyuki served as a bushō during the Sengoku and Azuchi-Momoyama periods. He was first a retainer of the Ukita clan, and, later, the Toyotomi clan.
Kageyuki was the son of Akashi Takenori, a retainer of the Ukita. He served as lord of Iwato Castle in the Wake District of Bizen Province managing a small fief of 2,000 koku. Kageyuki was the leader of a unit of forty arquebus-wielding foot soldiers.
In 1600, he joined his father, Takenori, to fight with the western army on behalf of Ukita Naoie at the Battle of Sekigahara, but was defeated. After departing the battlefield, he led a secluded life in Ashimori in Bitchū Province.
From 1614 to 1615, Kageyuki participated along with his father, Takenori, and son, Akashi Nobuyuki, in the Summer and Winter Campaigns of the Siege of Ōsaka. Nobuyuki was killed in action and Kageyuki’s was on the losing side of the battle, so he went into hiding again. Three years later, in 1618, Kageyuki received a pardon from the Edo bakufu, but died of illness thereafter.
After the death of his son, Nobuyuki, in the Siege of Ōsaka, Nobuyuki had earlier received Takemoto Masataka as a son-in-law from a wealthy family in Yoshinaga in the Wake District of Bizen, so Masataka became his heir. In the Edo period, Kageyuki’s descendants assumed the family name of Takemoto and served as village leaders. After the Meiji Restoration, the family name reverted to Akashi.
