About Isuzu
Isuzu Motors Ltd. now a Japanese multinational automobile manufacturer (HQ Yokohama, Kanagawa Prefecture) is specialized in commercial vehicles and diesel engines (diesel-powered truck, buses and construction vehicles) which spread its winds internationally to Anadolu Isuzu (Turkey), Sollers (Russia), SML Isuzu (India, former Swaraj Mazda), Jiangxi Isuzu Motors in China, a partnership with Jiangling Motors, Isuzu Astra Motor Indonesia, Isuzu Malaysia (HICOM), Industries Mécaniques Maghrébines, Isuzu UK, South Africa, Philippines, Taiwan, Vietnam, as well as Isuzu Motors India and BYD Isuzu. Manufacturing plants are located at Fujisawa, where the company was founded and Tochigi and Hokkaidō prefectures. Being familiar with trucks and 4x4 vehicles, it was only logical that the company would provide the new JSDGF. The company Name means "fifty bells". 
Historically, the company prior to this was Tokyo Automobile Industries Co., Ltd. founded to manufacture heavy duty trucks and passenger busses, and it became one of the primary manufacturers for the Imperial Japanese Army along with Mitsubishi Heavy Industries (Yasuda Zaibatsu). The 
Sumida M.2593 armored personnel carrier was one of its rare armoured vehicles. In 1942, Hino Heavy Industries emerged from Tokyo Automobile Industries and postwar, the company was renamed after the Isuzu River in 1949 after a reunion between the Ministry of Trade and Industry (MITI).
For the cold war Japanese Military, the company produced the TW340 medium truck, TWD20/25 medium truck, TSD45/TSD55 medium truck, HTS12G 2.5 ton truck and Type 73 Heavy Truck.
About Mitsubishi Fuso HI

 About as spectacular and best example of these multiple industrial branches, Mitsubishi was also a giant of armoured vehicles during the cold war, engineering all main battle tanks and armoured personal carriers of the JSDGF. The old Zaibatsu was founded as a shipping firm by Iwasaki Yatarō (1834–1885). It diveresified in ship contruction, aircraft construction, engines, and all sorts of vehicles, including those of the Imperial Japanese Army. As for more modern trucks, they emerged postwar of the Mitsubishi Fuso Truck and Bus Corporation (三菱ふそうトラック・バス株式会社) a brand separate founded in 1932 and specialized for trucks and buses, headquartered in Kawasaki (Kanagawa prefecture) but now own in majority by Daimler Truck. This also has benefits of technology transfer for heavy and specialized vehicles. "Fuso" in fact is a bywork for military Mitsubishi Trucks today.
Fuso motos sales was established in 1948, and in 1950, the split between the West/Central/East Japan Heavy Industries was yet reorganized again in 1952 whereas Fuso Motor Sales Company became the Mitsubishi Fuso Motors Sales Company. Under its guise a brand new generation of trucks, buses and speciality vehicles was built, inclusing those for the JSGDF. This was not over as by 1957, MNHI integrated the Tokyo and Kawasaki Works, creating the Tokyo Motor Vehicle Works which in 1964 fused into Mitsubishi Fuso Heavy Industries. Separated into the Shin and Fuso Motors Sales Company the distribution was split beteen heavy and light machinery. The former is now under the brand "fuso".
In MFHI transferred its motor-vehicle operations to MMC, in 1975, MMC opened the Nakatsu Plant (Tokyo Motor Vehicle Works) and in 1980 the Kitsuregawa Proving Grounds to test military vehicles of the company. In 1984 MMC merged with Mitsubishi Motor Sales Company and by 1985 MMC and Mitsubishi Corp. created a joint-equity called "Mitsubishi Trucks of America" to enter the US market. Later MMC would create a joint venture with Chrysler, Volvo joined in 1999 (adding more trucks and heavy vehicles skills) and MMC merged with DaimlerChrysler.
The company manufactured the following:
-Canter aka FE/FF/FG/FH from 1963 (also Sterling 360)
-Canter Guts (Canter Mini FA/FB/FC/FD)
-Fighter aka FH/FK/FM/FL (1984) and "The Great"
-Super Great/Heavy Duty aka FP/FS/FV (1996)
-Fuso FJ (India: BharatBenz)
-Fuso TV (Malaysia and Thailand)
-Fuso FI
As for proper military trucks, the one that replaced imported US M35s was the Type 73. This section will be completed over time. Notably Nissan and Toyota 1950s trucks. It should be added that before these models came around, the main military trucks in use were WW2 models as well as the early cold war M35 standard 6x6. As for light vehicles, Willys Jeeps were used.
About Hino Trucks (Toyota)

 Hino Motors, Ltd., is another specialist of trucks, buses and other specialized vehicles headquartered in Hino, Tokyo. Established in 1942 it was corporate spin-off from previous manufacturers, back to the Tokyo Gas Industry Company in 1910. In 1910, Chiyoda Gas Company was created to compare against Tokyo Gas Company for gas lighting users. Chiyoda GC later merged into Tokyo Gas in 1912 and the compan morphed into Tokyo Gas and Electric Industry (TG&E) or Gasuden, producing its first motor vehicle in 1917, the Model TGE "A-Type" truck. In 1937, TG&E merged with Automobile Industry Co., Ltd. and Kyodo Kokusan K.K., creating "Tokyo Automobile Industry Co., Ltd." and in 1941 Diesel Motor Industry Co., Ltd., later Isuzu.
In 1942 Hino Heavy Industry Co., Ltd. was created as a division of Diesel Motor Industry Co., Ltd. and notably manufactured for the IJA the 
Type 1 Ho-Ha half-track and 
Type 1 Ho-Ki armored personnel carrier. After 1946 it had to stop production of large diesels for marine applications and concentrated on heavy-duty trailer-truck, buses and diesel engine. By 1948, it separated into Hino Diesel Industry Co., Ltd and Hino Diesel Sales. The company however was no longer profitable in the 1960s and by 1966 an agreement was found to merge with Toyota. By April 1967, Hino started assembling light vehicles for Toyota. In the 1960s, Hino launched medium and heavy duty trucks such as the TC300, KF and by March 1964 the medium KM series "Ranger" and in the 1970s introduced the "red" diesel engines featuring better fuel efficiency with MAN technology.
