Designed and built by the Nambu Arms Manufacturing Company, the Type 100 was a robust, if unremarkable, submachine gun that was first delivered to the Imperial Army in 1942.

The Type 100 was a well made gun, albeit with several strange features, including a complicated ammunition feed device that, for safety purposes, ensured that a round was completely chambered before firing, a complex system compounded by the curious bottle shaped round the Type 100 used.

A number of Type 100 variants were produced during the course of the war; one with a folding stock and another that could be disassembled and stored in a pouch worn on the front of the torso for paratroopers (few with the folding stock were made as it weakened the weapon's structure in combat situations) and a 1944 version that was greatly simplified in order to hasten production at a time when Japan was being pushed into retreat across the Pacific theatre and demand for submachine guns was at an all time high. The 1944 variant was slightly longer, featured simple iron sights. Corners were cut in production, leaving many Type 100s with roughly finished stocks and poorly welded parts.
