Maizuru Naval Arsenal

With the addition of equipment and facilities for ship production by 1903, the Maizuru Naval Arsenal was officially established.

In 1923, after the Washington Naval Treaty, there were discussions within the Navy Ministry about closing the facility, and it was largely mothballed until 1936.

In the post-World War II period, a private company, Iino Industries Co. Ltd., took over and formed the Maizuru Shipyards.

The former head office and some warehouses associated with the shipyards are preserved as commemorative museums by the Maizuru city government.

Total: 41 of 153 (27%) of Japanese destroyers that were relevant during World War II.
