Sanjuro Group

The Sanjuro Group is the oldest of the large military contractors in Japan, established in 2018. At first they were merely a vehicles supplier, but in 2021 moved into the profitable small-arms business. Their first release was the SRM-7 sub-machine gun, built with patent licences from FN Herstal of Belgium due to similarities with their older P90 design. The SRM-7 uses the customized Sanjuro 5.56x31mm caliber, developed as a shortened version of the popular 5.56x45mm NATO round. The SRM-7 series are heavily used by the GSDF and NSF due to its compact size and handling, and has been in service since the year of its release. Capitalizing on the success of their SRM-7, Sanjuro released the MPN-45 machine pistol in 2024, using the same round as the SRM in a more compact package. The MPN-45 never caught on with the military due to concerns about the accuracy of such a short-barreled weapon, but proved to be highly popular with personal security details due to its ease of concealablity and impressive rate of fire.

Intending to develop a new weapon platform, and trying to avoid sub-machine guns, Sanjuro released the Klya-9 combat revolver in 2025, using a specially developed .45 round based off the .45 ACP cartridge. The Kyla-9 is a popular sidearm in the GSDF due to its reliability and stopping power. In 2027, Sanjuro introduced the PZ-252 Squad Automatic Weapon, a light machine gun chambered in the Remington 6.8mm SPC. The 252 is also another favourite of the GSDF with the polymer construction reducing weight to only 15 kilograms when dry, making it a highly portable source of sustained automatic fire.

Sanjuro seemed to abandon firearms for several years but in 2034 they introduced the NP-721 submachingun or “Jitte” as the designers nicknamed it. The NP-721 fires a high-velocity variant of the Sanjuro 5.56x31mm round designed to penetrate advanced combat armour. The NP-721 is rare among conventional forces due to its somewhat awkward handling, but is extremely popular among cybernetically-enhanced special forces units due to its ability to penetrate dense armoured chassis.
