Sengoku clan

• Japanese: 仙石家 (Sengoku ke)

The Sengoku clan were tozama daimyô of Izushi han in Tajima province.

They 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). Their lord was typically of Lower Junior Fifth Rank (従五位下), and the domain was ranked at 58,000 koku until 1835, when as the result of a succession dispute, it was lowered to 30,000 koku.

Sengoku Hisatoshi was lord of Izushi from 1825 through the end of the Edo period. Because he became daimyô at such a young age (age five), by the middle of his reign he had become the longest-serving daimyô in the Yanagi-no-ma, a position of some privilege and prestige.
