In 1688, Shōgun Tokugawa Tsunayoshi elevated his mother’s half-brother, Honjō Munesuke, to the rank of daimyō and assigned him a 10,000 "koku" territory on the former Ashikaga lands. He was later awarded an increase to 20,000 "koku" before being transferred to Kasama Domain in Hitachi Province in 1692.
