The Type 1 heavy machine gun (一式重機関銃, Ichi-shiki jū-kikanjū) was a heavy machine gun used by the Imperial Japanese Army during the later stages of the Second World War.

Though seemingly intended to replace the older Type 92 heavy machine gun, the weapon never underwent the same level of mass production as its predecessor due to either material shortages or the fact that the Type 92 heavy machine gun was deemed as acceptable.

It employs the same principles of operation, simply with scaled down components.

The overall rate of fire was higher than that of the Type 92 heavy machine gun.
