''"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 is based on British QF 4.7in. Mk.IV gun, which later producted domestically in Japan. The barrel of this gun was later mounted to high-angle mounting and served as AA guns for early Japanese heavy cruisers (ie. Furutaka-class to Takao-class. Both classes had its AA gun changed for [[12.7cm Twin High-angle Mount|12.7cm twin]] afterward, but Chokai alone was equipped with 12cm single throughout her career).
