Yokosuka is a major city located in Kanagawa Prefecture, Japan. 
Human history in this region spans thousands of years. Archaeologists have discovered stone tools from the Japanese Paleolithic period here. They have also found ceramic shards from the Jōmon and Kofun periods. In 1063, a local warlord named Muraoka Tamemichi built Kinugasa Castle. This established the Miura clan as a dominant force in the area. The clan ruled the Miura Peninsula for several centuries. They were eventually defeated by Hōjō Sōun at Arai Castle in 1518. Later, in 1590, the region came under the control of Tokugawa Ieyasu.
Significant global connections arrived in the early 1600s. In 1600, the English sailor William Adams arrived at Uraga. He was the first Briton to set foot in Japan. Because of his service to the Tokugawa shogunate, he became a samurai. He was granted a fief in Hemi within modern Yokosuka. Today, a monument to Adams serves as a local landmark. During the Edo period, the Shogunate controlled this territory directly. Because of its strategic location, the Shogunate established the Uraga Bugyō post in 1720. This required all ships entering Tokyo Bay to stop for inspection.
In the mid-1800s, Yokosuka became a center for modern industrialization. In 1853, Commodore Matthew Perry arrived with his "Black Ships." This event led to new diplomatic and trade relations between Japan and the United States. Following this, the Shogunate selected Yokosuka for a modern naval base. In 1865, they hired a French engineer named Léonce Verny. He oversaw the development of shipbuilding facilities like the Yokosuka Iron Foundry. 
During the Meiji period, the area underwent significant reorganization. The Yokosuka Naval Arsenal was taken over by the Imperial Japanese Navy. In 1889, the Yokosuka Line railway opened to connect the city to Tokyo and Yokohama. The city officially gained city status on February 15, 1907. The naval presence grew, including the development of the Naval Air Technical Arsenal at Oppama. This facility tested many combat aircraft for the Imperial Japanese Navy Air Service. The arsenal also produced massive battleships like the Yamashiro and aircraft carriers like the Hiryū. 
The city's landscape changed significantly during World War II. In 1942, American B-25 Mitchell bombers conducted the Doolittle Raid on Yokosuka. To protect workers from air attacks, the military built extensive underground networks. Between 1938 and 1945, workers built over 260 caves. These tunnels spanned at least 27 kilometers within the naval base alone. These facilities included a 500-bed hospital and a midget submarine factory. After the war, American occupation forces landed at Yokosuka on August 30, 1945. Since then, the United States Navy has used the naval base.
Today, Yokosuka is both a military and industrial hub. It is home to United States Fleet Activities Yokosuka. This presence means there are several hundred Americans and a thousand Filipinos living in the city. The economy is also driven by large manufacturing plants. Nissan Motors operates factories here that assemble models like the Leaf, Cube, and Juke. These plants have been operating since 1961. Additionally, the Yokosuka Research Park is a center for the telecommunications industry. Every May, the city hosts a festival celebrating Japanese curry, which attracts 50,000 people.
Visitors can explore many unique cultural and historical sites. You can take a ferry to the uninhabited island of Sarushima. Another attraction is the Mikasa, a famous flagship preserved as a museum. For modern architecture, the Yokosuka Museum of Art is a notable destination.
