Tax and insurance benefits in some locations make these models particularly inexpensive. For example, in rural Japan, kei-car vehicles are exempted from a certification that adequate parking is available for the vehicle.2 They are, therefore, widely used for small businesses in these places.
The first vehicle to adopt the bodystyle of a van, with the engine installed in front of the driver, was the 1970s Honda Life "StepVan". Some microvans use a drivetrain with the engine installed transversely, using front- or all-wheel drive, while others use a cabover approach where the engine is installed beneath the driver, while still using all-wheel or rear-wheel drive powertrains. Cabover variants usually share their chassis with kei truck derivatives from the same manufacturer.
Most microvans have two swinging front doors, two sliding rear doors and a large tailgate. Seating can vary from two to nine; these seats are usually very thin and vertical to optimise room. The side windows in commercial-only versions of microvans are replaced by metallic panels; this type of microvan is sometimes called a "blind van". Some models also feature pick-up variants with one or two seat rows. Engines usually have displacements under 1.0 L; for example, Japanese microvans have a limit of 660 cc. Outside the Japanese market, microvans are available with 850-cc to 1.6-L engines.
The kei car regulation is used only in Japan, though other Asian automakers also design microvans with similar characteristics. The microvans are commonly known as "kei one-box" in Japan; their pick-up versions are known as kei trucks.
