During the Heian period, local warlord Muraoka Tamemichi established Kinugasa Castle in 1063. He became the ancestor of the Miura clan, which subsequently dominated eastern Sagami Province for the next several hundred years. The Miura clan supported Minamoto no Yoritomo in the foundation of the Kamakura shogunate, but were later annihilated by Hōjō Tokiyori in 1247. However, the family name was reassigned to a supporter of the Hōjō clan, and the Miura continued to rule Miura Peninsula through the Muromachi period until their defeat at Arai Castle in a 1518 attack by Hōjō Sōun. Following the defeat of the Later Hōjō clan at the Battle of Odawara, Toyotomi Hideyoshi transferred Tokugawa Ieyasu to take control over the Kantō region, including Yokosuka in 1590. The adventurer William Adams (inspiration for a character in the novel Shōgun), the first Briton to set foot in Japan, arrived at Uraga aboard the Dutch trading vessel Liefde in 1600. In 1612, he was granted the title of samurai and a fief in Hemi within the boundaries of present-day Yokosuka, due to his services to the Tokugawa shogunate. A monument to William Adams (called Miura Anjin in Japanese) is a local landmark in Yokosuka. During the Edo period, Yokosuka tenryō territory was controlled directly by the Tokugawa shogunate, but administered through various hatamoto.
