Kei cars

Kei car, K-car, or kei jidōsha (軽自動車^?, lit. "light automobile") (pronounced [keːdʑidoːɕa]), is a Japanese category of small vehicles, including passenger cars (kei cars or kei-class cars), microvans, and pickup trucks (kei trucks or kei-class trucks). They are designed to comply with Japanese government tax and insurance regulations, and in most rural areas are exempted from the requirement to certify that adequate parking is available for the vehicle. This especially advantaged class of cars was developed to popularize motorization in the postwar era. While successful in Japan, the genre is generally too specialized and too small to be profitable in export markets.

The cars feature yellow license plates, earning them the name "yellow-plate cars" (black numbers on yellow background for private use and yellow numbers on black background for commercial use) in English-speaking circles. Because regulations only restrict physical size and engine displacement (and latterly outright power), manufacturers have been able to introduce many advanced technologies to the class. As a result, kei cars are often available with forced-induction engines, automatic and CV transmissions, front-, rear-, and four-wheel drive, air conditioning, GPS, and many other features.
