The first generation Toyota Estima was introduced in Japan in 1990. The right hand drive Estima was smaller than its North American counterpart, the Toyota Previa due to vehicle tax impliations in Japan. Despite its smaller size, the Estima shares many body panels, interior pieces and suspension components as the Previa making it a popular import choice in Canada.

Canadian Rural Mail Carriers have demanded the Estima for right hand drive mail routes due to its parts availability, diesel engine offering and available 4WD, the latter being options not found on the left hand drive Previa.

Other things that make the Estima a popular import choice are its trim levels, over 40 in total, ranging from standard configurations to luxury.
