"The older main gun for small vessels. Equipped as standard weapon on old destroyers. Both loading and rotation was hand-operated, but with its simple construction and low cost, it served a long time as main weapon of destroyers and escorts. Not intended for anti-air firing."
This gun's basic structure was based on the British QF 4.7in. Mk.IV gun, which was later produced domestically in Japan. The barrel of this gun was later mated to a high-angle mounting and served as AA guns for early Japanese heavy cruisers (ie. Furutaka-class to Takao-class. Both classes had their AA guns exchanged for 12.7cm twin afterwards, but Chokai alone was equipped with 12cm singles throughout her career).
