お家騒動
was the 4th "daimyō" of Miharu Domain and 6th hereditary chieftain of the Akita clan. His courtesy title was "Shinano-no-kami", and his Court rank was Junior Fifth Rank, Lower Grade. He was the eldest son of Araki Takamura, a retainer of and distance relative of the Akita clan who had taken over the reins of the domain during the incapacity of Akita Terusue after the death of his son, Narisue. He was adopted by Akita Terusue in 1715 and was received in formal audience by Shōgun Tokugawa Ietsugu the same year. He also married Norisue's daughter. Later that year, Terusue resigned from all his titles and posts. He became "daimyō" on Terusue's death in 1720. This succession resulted in an "O-Ie Sōdō" by clan members who were opposed to Araki's power and position within the domain; however, the Tokugawa shogunate chose not to intervene and the issued died down with Araki's retirement. Yorisue's grave is at the temple of Kōken-in in Miharu.
