Akō Castle in the city of Akō

The Akō Domain (赤穂藩 Akō Han?) was a domain in feudal Japan. It was located in Harima Province and coincided with the present-day cities of Akō and Aioi and the town of Kamigōri in Hyōgo Prefecture. The domain had its headquarters at Akō Castle.

In 1615, the Tokugawa shogunate granted the Akō domain to Ikeda Masatsuna. He died without heir in 1631, and the domain passed to his brother Teruoki. However, Teruoki became deranged, and in 1645 he was dismissed; the domain was ruled by the main line of the Ikeda family until the appointment of Asano Naganao later that year. Under the Asano, the domain reached its highest rating of 53,000 koku.

Naganao's grandson Naganori was the daimyo of Akō at the time of his attempt to kill Kira Yoshinaka in Edo Castle in 1701. He was sentenced to commit suicide and his retainers became ronin. A group of them became famous as the Forty-seven ronin.

The domain passed to Nagai Naohiro, who was transferred elsewhere in 1706. Akō then passed to Mori Naganao. He and his heirs ruled the domain for twelve generations until the abolition of the han system in 1871. The rating of the domain was 20,000 koku.
