千葉氏
The Chiba clan, allies of the Hōjō in Shimōsa, also saw Sakura Castle fall to Honda Tadakatsu and Sakai Ietsugu of the Tokugawa army during the campaign. Chiba Shigetane, "daimyō" of the Chiba, surrendered the castle to the besieging forces on the condition that his clan would not be abolished. While the Chiba were consequently divested of all of their holdings, many of their senior members were taken into service by Tokugawa retainer Ii Naomasa, thanks to aid he had received many years earlier from the clan during the occupation of Takeda Katsuyori's Tsutsujigasaki Castle.
