Production of the fourth generation commenced in Japan on 29 May 2018 at Suzuki's Kosai plant.

Images of the fourth generation Jimny were leaked on the internet in August 2017. 

The official images of this Jimny were revealed on 19 June 2018. The fourth generation Jimny and Jimny Sierra was launched in Japan on 5 July 2018. It has a retro style with a boxy design, not only reminiscent of the earlier LJ and SJ Jimny generations, but one that has also been called a small cross-breed between the Mercedes G-Wagen and the Land Rover Defender.
