横須賀藩
The Kakegawa area has been regional commercial center within Tōtōmi Province since at least the Kamakura period, but developed as a castle town under the Imagawa clan, whose headquarters was in neighboring Suruga Province. Kakegawa Castle was built by Asahina Yasuhiro, a retainer of Imagawa Yoshitada, in the Bunmei era (1469–1487). The castle later fell into the hands of the Tokugawa clan, but was then given to Toyotomi clan retainer Yamauchi Kazutoyo in 1580. After the establishment of the Tokugawa shogunate, Kakegawa Domain was created, and ruled by numerous "fudai" daimyō. The area prospered during the Edo period, as the Tōkaidō highway connecting Edo with Kyoto passed through Kakegawa, whose post stations included Nissaka-shuku and Kakegawa-juku. Neighboring Yokosuka Domain, a smaller "fudai" holding, was also located within what are now the city limits of Kakegawa.
