The first generation model of Mitsubishi's compact pickup truck was first sold in Japan as the Mitsubishi Forte in September 1978 and continued until late 1986, when the line was cancelled in the Japanese domestic market for five years. In Japan the Forte was originally sold with the 1.6-litre 4G32 engine (L021P). Later this was updated to the 1.6-litre G32B engine with two-wheel drive (LO25) or with four-wheel drive coupled to the 2.0-litre Sirius G63B with (L026). Offered in basic Deluxe trim, the larger-engined version was also available in leisure-oriented Custom trim. The Custom also has a smoother and less utilitarian bed, without provisions for fitting a canvas top and with fewer hardpoints for strapping down loads.
