Kei trucks, also known as kei-class trucks or Japanese mini trucks, are compact, lightweight vehicles originating from Japan, designed to meet specific size and engine displacement regulations. Renowned for their efficiency, reliability, and versatility, these trucks are widely used in various industries such as agriculture, construction, and small-scale transportation, and have gained popularity beyond Japan for their practicality and affordability.


Evolution of Kei Trucks: From Three-Wheeled to Four-Wheeled
Kei trucks originated in post-World War II Japan, driven by economic and resource constraints that necessitated the development of economical and practical transportation. The Japanese government introduced the "Keijidosha" (light vehicle) regulations in 1949, which set strict limits on vehicle dimensions, engine displacement, and weight to promote fuel efficiency and reduce material demand.
  • The first Kei truck, the Kurogane Baby, was introduced in 1959, followed by the Subaru 360 Sambar in 1957, which featured a 2-cylinder, 2-stroke engine.
  • Early models like the Subaru Sambar quickly became popular for their practicality in small businesses, farming, and urban commuting.
  • Over the years, Kei trucks evolved from basic, utilitarian vehicles to more sophisticated machines with advancements in engine technology, safety features, and comfort.
  • The introduction of four-wheel drive (4WD) and all-wheel drive (AWD) systems expanded their off-road capabilities, making them valuable for agricultural work and outdoor activities.
  • Today, Kei trucks are recognized globally for their compact size, efficiency, and versatility, with applications ranging from mini-campers to mobile cafes. favicon favicon favicon
