Reading up on the history of a location before visiting it will give you an enlightened view of the area. Some Yokosuka facts plucked from
Wikipedia below. 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 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 Shogun. There he founded a family with Oyuki, the daughter of Magome Kageyu, a noble samurai and official of Edo Castle. William and Oyuki had a son called Joseph, and a daughter, Susanna. A monument to William Adams (called Miura Anjin in Japanese) is still visible in Yokosuka.
