What is a Kei Car? Kei cars are a specific category of small, lightweight vehicles that originated in Japan. They’re designed to comply with certain regulations and size restrictions that make them more affordable to own and operate in Japan’s urban environments. These cars have a limited engine size (660cc) and dimensions, which result in lower taxes and insurance costs for their owners. Despite their small size, they can often accommodate up to four passengers comfortably. Kei cars are popular in Japan due to their fuel efficiency, easy maneuverability in crowded cities, and cost-effectiveness.

The specific maximum size regulations for kei cars in Japan typically include restrictions on length, width, height, and engine displacement. Here’s a table summarizing these limitations:

AspectMaximum Limit for Kei Cars
Length3.4 meters (11.15 feet) or less
Width1.48 meters (4.86 feet) or less
Height2 meters (6.56 feet) or less
Engine Displacement660cc or less

These specifications are crucial for a vehicle to be classified as a kei car in Japan and benefit from the associated tax breaks and other advantages.
