A Kijiro Nambu modification of the French Hotchkiss machine gun, the Type 11 was the first light machine gun that Japan produced in large quantities and the oldest Japanese LMG design to see service in the Pacific war. The Type 11 used a non-detachable hopper magazine that held six cartridge clips as used for the Type 38 Arisaka Rifle. The clips were stacked lying flat above the receiver, an unusual but surprisingly reliable feed system, although the gun was liable to jam in muddy or dirty conditions. This system also made speedy reloading during assaults impossible. Type 11 machine guns were also available with a special mounting for anti-aircraft use.
