The 7 cm mountain gun was a Japanese ordnance first used in 1883. Because of the relative expense of steel at the time, the gun was produced with a bronze barrel. The 7 cm was used in the First Sino-Japanese War as the main artillery, and was used again in the Russo-Japanese War by second-line troops.
