History
When Commodore Matthew Perry arrived in Japan in 1853, using naval pressure to open up Japan to foreign trade, Yokosuka was a quaint, native fishing village. In 1860, Lord Oguri Kozukenosuke, Minister of Finance to the Tokugawa Shogunate Government, decided that "If Japan is to assume an active role in world trade, she must have proper facilities to build and maintain large seagoing vessels." He called upon the French Consul General, Léon Roches, and asked for the assistance of the French government to build a shipyard and various basing facilities capable of handling large ships. French engineer Léonce Verny was sent to Japan to accomplish the task.
After the inspection of several sites, it was discovered that Yokosuka topographically, if on a smaller scale, resembled the port of Toulon, France. It was decided to establish the shipyard here. It would be called the "Yokosuka Iron Works". In 1871, the name was changed to the "Yokosuka Navy Yard". It was French engineer Louis-Émile Bertin who reorganized "Yokosuka Navy Yard" completely from 1886.

Yokosuka was to become one of the main arsenals of the Imperial Japanese Navy into the 20th century. Battleships such as Yamashiro, and aircraft carriers such as Hiryu and Shokaku were built there. Major naval aircraft were also designed at the Yokosuka Naval Air Technical Arsenal. In addition, numerous other facilities, including the headquarters of various naval units, administration buildings, military training schools, airfields, communication facilities, barracks, armories and a military hospital were established nearby in the course of its history, turning the area around the arsenal into a major fleet base.
During World War II, activities at the Yokosuka Navy Yard reached their peak. By 1944, it covered 280 acre and employed over 40,000 workers. In addition to the shipbuilding plant, the yard also had a gun factory, ordnance and supply depots, a fuel storage facility, a seaplane base, and a naval air station.
