A medium-ranged gun that was developed domestically as the main gun of light cruisers and secondary gun of battleships.
Although it is slightly obsolete, it still has range and power comparable to 15 cm guns from the other major powers.
It is designed for surface combat so it is unable to be used for anti-air.

Used as Japanese post-Tenryu class light cruisers' main armament, as well as battleships' secondary gun in Ise class and Nagato class. The original secondary battleship gun was calibrated at 15.2 cm but the shell weighing more than 40 kg was rather too heavy to be handled by hand, thus came the smaller calibered 14 cm gun. The momentum of the shell itself decreased slightly but the range remained the same, and it also has an increased firing rate at a maximum of 10 rounds/min. The fleet's food supply ship, Mamiya was also equipped with this gun. Also, a twin-mount version existed and was used by Yuubari and the Katori-class.
