The Imperial Japanese Navy began moving to the metric system from the Imperial system during the Taishō period and as a result, most of their older guns were re-designated to conform to the new bureaucracy even though the guns were mostly unchanged from their Meiji era designs. An example is the 8-centimetre 40-calibre 3rd Year Type (the re-designation having occurred in the third year of Emperor Taishō's reign, 1917) formerly the 3-inch/40 Type 41. The design did undergo some changes later in its life, but the original guns were still overall similar to the Type 41 that came before. The first change to occur was adding a sliding breech block and later variants of the design were built with monobloc barrels. The Japanese battleships and battlecruisers built between 1914 and 1925 used these weapons as anti-aircraft guns. While they were later phased out from this role after 1925, the guns would be used well into World War II on smaller ships such as cruisers, destroyers, armed merchantmen, gunboats, and so on. Mounted on an elevating mount, these weapons were intended to be dual-purpose guns and also dismounted from ships in the coastal defense role. A wet mount called Type 88 was developed for mounting on submarines. In the coastal defense role, the guns were used to defend a large number of IJN island bases including Kiska, the Aleutian Islands in Alaska, Kolombangara in the New Georgia Islands group of the Solomon Islands, Saipan and Tinian in the Northern Mariana Islands, and Tarawa in the Gilbert Islands (now the capital of the Republic of Kiribati).
