Type 89 refers to two unrelated Imperial Japanese Army aircraft machine guns. Its Imperial Japanese Navy counterparts are the Type 97 machine gun (fixed), and Type 92 machine gun (a Lewis gun copy).

The first machine gun is a recoil-operated, licensed copy of the

Ki-43, early Ki-44 fighters, the Mitsubishi Ki-30 and Ki-51 light bombers, the Kawasaki Ki-32 light bomber and various others. Communist forces used some ex-Japanese Type 89s during the Korean War.[3] Indonesian Republican forces also used them for ground use during the Indonesian National Revolution.[4]

The second machine gun is

Type 11 machine guns paired into a single unit, similar to the German MG 81Z. It is commonly referred to as the "flexible type".[citation needed] It was derived from otsu-gou - an experimental machine gun (1922-1929) which was a Type 11 turned on its side and fed from a pan magazine.[2] The machine gun was chambered in the 7.7x58mmSR Type 89 cartridge, it used a Y-shaped metallic stock, spade grips, the barrels had no cooling fins (contrary to Type 11), it was fed from two quadrant-shaped 45-round pan magazines (each magazine has a place for nine 5-round stripper clips).[5]
The machine gun was used as a rear gun on aircraft and some were pressed into ground and anti-aircraft use.[citation needed] Single or doubled Type 89s were used in most Imperial Japanese Army aircraft that had flexible defensive weapons, including the Mitsubishi Ki-21, Ki-67 and Nakajima Ki-49 heavy bombers, the Mitsubishi Ki-30, Ki-51 and Kawasaki Ki-32 light bombers, the Tachikawa Ki-9 (for training purposes only), and various other aircraft in the Army Air Force inventory.

Additionally, there was also the Te-4 machine gun (the Te designation was given to firearms under 11mm, and Ho to larger weapons such as the 12.7mm Ho-103 heavy machine gun and 20mm Ho-5 autocannon), the machine gun bore a strong resemblance to otsu-gou (of which the Type 89 "flexible" was a derivative),[2] due to that fact it was assumed to be a further modification of the double-barrelled machine gun, as such it was referred to as Type 89 "modified single".
