wasn't in reference to "CJ3", but rather denoted the fact that 53 "J1"s (CJ-3A with 6-volt electrics) had been built for the Japanese regional forest office and around 500 "J2"s (CJ-3A with 12-volt electrics) were built for the National Safety Forces. Mitsubishi continued knock-down production of vehicles derived from the CJ-3B design until August 1998, when tighter emissions and safety standards finally made the Jeep obsolete. In total, about 200,000 units were built in this 45-year period. Short, medium, and long wheelbases were available, as well as a variety of bodystyles, and gasoline and diesel engines. In Japan, it was sold at a specific retail chain called Galant Shop. The Japanese GSDF refers to them as Type 73 Light Truck. The original J3 was a basic, doorless, and roofless version, with steering on the left, rather than the right, despite Japan having left-side traffic. The first right-hand drive versions did not appear until nearly eight years later (J3R/J11R). The original J3 and its derivatives were equipped with the F-head "Hurricane" (called JH4 by Mitsubishi, for Japanese Hurricane 4-cylinder) inline four-cylinder, originally producing at 4,000 rpm. In 1955 a slightly longer wheelbase J10 which could seat six was added, and in 1956 the J11 appeared, a two-door "delivery wagon" with a full metal body. This was considerably longer, at versus for the J3. Local production of the JH4 engine commenced in 1955. A locally developed diesel version (KE31) was introduced for the JC3 in 1958, originally with at 3,500 rpm but with at 3,600 rpm a few years later. Later versions used 4DR5 and 4DR6 (J23 turbo) 2.7 liter overhead-valve diesel engines. The final military version J24A produced 135PS from an improved 4DR5 engine with front-mounted air-to-air intercooler. By 1962, the output of the gasoline JH4 engine had crept up to . By the time of the introduction of the longer J20 in 1960, a six-seater like the J10, but with a differently configurated (more permanent) front windshield, as well as available metal doors, Mitsubishi had also added small diagonal skirts to the leading edge of the Jeep's front fenders. This remained the last change to the sheetmetal up front until the end of Mitsubishi Jeep production in 1998. Later models include 2-L, short-wheelbase, soft-top J58 (J54 with a diesel engine), and the J38 gasoline wagon on the longest wheelbase. The last iteration of the Japanese Jeeps was the J53 with
