Kururi Domain

Kururi Domain (久留里藩, Kururi-han^?) was a feudal domain under the Tokugawa shogunate of Edo period Japan, located in Kazusa Province (modern-day central Chiba Prefecture), Japan. It was centered on Kururi Castle in what is now the city of Kimitsu, Chiba.

The original Kururi Castle was a mountain-top fortification built during the Muromachi period by Takeda Nobunaga (1401–1477), and was ruled by his descendants, the Mariya clan, from 1540. With the expansion of the Satomi clan from Awa Province in the Sengoku period, the castle was taken over by Satomi Yoshitaka, who used it as his base of operations against the Hōjō clan, based at Odawara Castle. The Hōjō attempted to take Kururi unsuccessfully on a few occasions, and finally seized it in 1564. They lost it just three years later in 1567, when the Satomi regained control.

Following the Battle of Odawara, Toyotomi Hideyoshi punished the Satomi clan for their lukewarm support of his campaigns by depriving them of their territories in Kazusa Province. With the entry of Tokugawa Ieyasu into the Kantō region, he assigned the fortifications at Kururi to one of his retainers, Matsudaira (Osuga) Tadamasa, the son of one of his Four Generals, Sakakibara Yasumasa, and appointed him as daimyō of the newly created 30,000 koku Kururi Domain.
