Following the Battle of Odawara in 1590, Toyotomi HIdeyoshi assigned the Kantō region to Tokugawa Ieyasu, who confirmed the Satomi as daimyō of Awa and Kazusa Provinces, with revenues of 92,000 "koku". Following the Battle of Sekigahara, Satomi Yoshiyasu also gained control of Kashima District in Hitachi Province, which increased his holdings to 122,000 "koku". After his death in 1603, the domain was inherited by his son, Satomi Tadayoshi. However, Tadayoshi was related by marriage to Ōkubo Tadachika, and was implicated in the Ōkubo Nagayasu Incident of 1614, which the Tokugawa shogunate used as excuse to abolish Tateyama Domain.
