She was the last notable survivor of the clan after the Siege of Osaka; being responsible for continuing the Chōsokabe's lineage in Sendai domain when she became retainer of Date Masamune.

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.

The lands of the Chōsokabe clan had been confiscated after the end of the Siege of Osaka, but Akohime who was spared from death used her influence to continue the Chosokabe lineage.

In 1671, during the Date Disturbance, he died in a sword fight against Harada Munesuke at the residence of Sakai Tadakiyo.

While serving as a personal maid to Masamune, Akohime requested of her cultured lord a work of calligraphy for which he wrote a song from Kiyohara no Motosuke, a revered noble and poet from the tenth century in the Heian period.
