里見氏
The area of present-day Minamibōsō was part of ancient Awa Province, dominated by the Satomi clan during the Sengoku period, and mostly "tenryō" territory controlled directly by the Tokugawa shogunate, with portions under the control of various minor feudal domains. The area was divided into numerous towns and villages in the Meiji period, all within Awa District of Chiba Prefecture.
