What is a Kei Car?

A Kei car is a category of small-sized vehicles that are popular in Japan. They are also known as K-cars and are designed to be practical, fuel-efficient, and affordable. These vehicles are restricted by certain regulations set by the Japanese government, such as engine displacement and maximum dimensions. Kei cars are classified based on their engine size and power output, and they typically have engines with a maximum displacement of 660cc.

History of Kei Cars

Kei cars were first introduced in Japan in the 1940s as a way to provide affordable transportation for the masses. In the 1950s, the Japanese government established a new class of vehicles, known as “Light Automobiles.” These cars had a maximum displacement of 360cc and were designed to be even more affordable and fuel-efficient than traditional cars.

Over the years, the regulations and requirements for Kei cars have changed and evolved. In the 1970s, the maximum engine displacement was increased to 550cc, and by the 1990s, it was increased to the current maximum of 660cc. Today, Kei cars are a common sight on Japanese roads, and they account for around a third of all new car sales in the country.

Benefits of Kei Cars

There are several benefits of owning a Kei car in Japan. One of the main advantages is their fuel efficiency. Kei cars are designed to be incredibly economical, with many models capable of achieving more than 50 miles per gallon.

Another advantage of Kei cars is their affordability. These vehicles are often cheaper than traditional cars and are considered a good investment for people who live in urban areas, where high gasoline prices and parking fees are common.

Finally, Kei cars are usually smaller than traditional cars, which means they are easier to maneuver in tight city streets. This can be a big advantage for people who live in crowded urban areas, where parking spaces are often limited.


Overall, Kei cars are an important part of Japanese car culture and offer many benefits to drivers in the country. Despite their small size, these vehicles are practical, fuel-efficient, and affordable, making them an attractive choice for many people who live in urban areas. Whether you are looking for a new car or simply want to learn more about the unique world of Kei cars, there is no doubt that these vehicles are an interesting and important part of the automotive landscape in Japan.
