The Sumitomo LMG was a light machine gun being developed by Sumitomo Heavy Industries to replace the FN Minimi used by the Japan Ground Self-Defense Force. In April 2021, Sumitomo announced it was withdrawing from machine gun production, effectively canceling this light machine guns development.

Design and development
The machinegun was patented on March 26, 2018.

The firearm is described as a "multi-caliber" machinegun, in that it is compatible with different ammunitions while retaining the same overall design. This is achieved by the machine gun's modular design. When changing to a different ammunition, the barrel, the feed system that takes in the belt link, and the bolt carrier are replaced while the rest of the gun remains intact. According to Sumitomo's patent, when compared to conventional methods, their method reduces the number of dedicated parts for each caliber. This in turn reduces the burden for the user to learn the operational method and maintenance procedure of the machine gun, as well as making it easier to manage parts.

Concerns have risen about the viability of producing this machine gun, due to Japanese firearm manufacturing technology lagging behind countries, as well as Sumitomo's own problems with quality control with their past machine guns. The Sumitomo LMG was likely to face stiff competition from other high quality machine guns, such as the Heckler & Koch MG5.

In April 2021, Sumitomo announced it was withdrawing from machine gun production, effectively canceling this light machine guns development.
