Shimuzu produces mostly All-Terrain Vehicles (more commonly known as ATVs), but it's also making Jet Skis and pick-up style cars. Judging by the sound and spelling of the name, it might be a Japanese company.
There's a glitch in Just Cause 2 that allows the player to use a two handed weapon on any of the Shimuzu ATVs (except for the ATV 55T). Usually it's only possible to use single handed weapons on a vehicle. The player has to Stunt-jump from a Parachute onto an ATV. Note that you have to be airborne for this glitch to work.
