Akohime was the daughter of Chōsokabe Motochika, known for having unified the island of Shikoku. She was also the sister of
Chōsokabe Morichika and wife of
Satake Chikanao, a retainer of the Chōsokabe, and bore two sons which would later be known as Igarashi Motonari e Shibata Tomomoto. In 1615, during the Summer Campaign of the
Siege of Ōsaka, Akohime accompanied the Chōsokabe army who were allies of the Toyotomi clan in the fight against the Tokugawa clan. Akohime, Chikanao and Chōsokabe Morichika enter Ōsaka Castle, but the Toyotomi lost the battle while Chikanao was killed in action. When Ōsaka Castle fell, Akohime and her two sons were captured by soldiers under the command of
Date Masamune, the head of the Sendai domain. Masamune spared the lives of Akohime and her sons, after which Akohime served as a personal maid of the Date family under the name of Chūjō. == Chōsokabe influence in Sendai ==
