The Suzuki Wagon R is a kei car manufactured and marketed by Suzuki since 1993. The R in the name stands for Revolution and Relaxation. The Wagon R uses a "tall wagon" configuration to maximize cabin space within kei car dimensional restrictions. The Wagon R is also sold by Mazda as the AZ-Wagon from 1994 to 2012 and as the Flair from 2012.

Kei car is the smallest category of Japanese, expressway-legal motor vehicles. 'Kei' is diminutive for kei-jidōsha,, "light automobile" or "compact automobile". With restricted dimensions and engine specifications, owners benefit firstly from lower taxes and insurance rates which lead to a lower overall cost of ownership. And in most rural areas, importantly, they were also exempted from the general Japanese shako shōmeisho (車庫証明書) parking-space ownership requirement to legally buy a motor vehicle at all, as street parking is generally restricted in Japan. Japan's carmakers also make microvans and kei trucks within this legal category.
