The Maizuru Naval District was established at Maizuru, Kyoto Prefecture in 1889, as the fourth of the naval districts responsible for the defense of the Japanese home islands. After the establishment of the navy base, a ship repair facility was established in 1901 with a dry dock. With the addition of equipment and facilities for ship production by 1903, the Maizuru Naval Arsenal was officially established.
