The Kure Naval District was established at Kure, Hiroshima in 1889, as the second of the naval districts responsible for the defense of the Japanese home islands. Along with the establishment of the navy base, a ship repair facility was also constructed, initially by moving the equipment from the Onohama shipyards near Kobe. Construction was supervised by the French engineer Louis-Émile Bertin. The first warship constructed at Kure, Miyako, was launched in 1897. The "Kure Shipyards" were officially renamed the "Kure Naval Arsenal" in 1903.

Kure developed into one of the largest shipbuilding facilities in the Empire of Japan, capable of working with the largest vessels. The Arsenal included a major steel works (built with British assistance), and also facilities for producing naval artillery and projectiles. The battleships Yamato and Nagato were designed and constructed at Kure.

The facilities of the Kure Naval Arsenal were repeatedly bombed by the United States Navy and United States Army Air Forces during the Pacific War, and over 70% of its buildings and equipment was destroyed.

After the surrender of Japan in 1945, the Kure Naval Arsenal was turned over to civilian hands.

The extensive dry dock, ship building, repair and engineering facilities are now owned and operated by Japan Marine United, one of Japan's largest merchant marine and naval shipbuilders.
