Satomi clan
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.
