According to the source, Japanese minicars or kei cars are vehicles that are shorter than 3.4 meters with a maximum height of 2 meters and a maximum width of 1.48 meters. The engine capacity is restricted to 0.66 liters measured by Japanese standards. Kei cars are often box shaped in order to minimize the overall size of the vehicle while maximizing interior space.
In 2025, Honda’s N-Box was, once again, the best-selling kei car model in Japan, reaching a sales volume of ** units. The often box-shaped light motor passenger vehicles, known as kei cars in Japan, are a distinctive feature of the domestic automotive market and scarcely sold outside the country.
