The Sengoku were a "castle-holding" (shiro-nushi or shiro-mochi) daimyô family assigned to the yanagi-no-ma of Edo castle. Their upper mansion (kami yashiki) in Edo was located in the Nishinokubo neighborhood (today, Minato-ku, Kamiyachô).
As the result of an internal succession dispute, the domain's kokudaka was reduced in 1835 by 28,000 koku, such that through the end of the Edo period, the domain's kokudaka was only 30,000 koku. The daimyô at that time was Sengoku Sanuki-no-kami Hisatoshi; Hisatoshi was only fifteen at the time, and remained lord of Izushi through the remainder of the Edo period.
