Location and layout
The base is located at the entrance of the Tokyo Bay, approximately 18 miles south of Yokohama, in the Kanto Plain region of Japan. It is situated about 30 miles south-west of the Japanese capital, Tokyo, and occupies a 568-acre site.
Yokosuka Naval base was built in 1860s as a 280-acre shipyard to help Japan play active role in the world trade. It was named Yokosuka Iron Works at the time, and renamed Okosuka Navy Yard in 1971. Activities at the base reached peak levels during World War II, when the yard employed more than 40,000 workers 1944.
In August 1945, the base was surrendered to the Allies and peacefully occupied by the US Marines, UK Marines and the US Naval forces. CFAY was established shortly after the occupation.
In May 1946, the marines at Yokosuka were re-designated as Marine Barracks, US Fleet Activities, Yokosuka. In April 1947, the Ship Repair Department (now US Naval Ship Repair Facility) was formed and the stores and dry docks were reactivated to handle the US Pacific Fleet.
With the outbreak of Korean War in June 1950, the base abruptly turned into a very crucial and extremely busy installation. The US Naval Hospital and the Naval Communications Facility, Yokosuka were established in 1950 and 1951 respectively.
