The Toyopet Master, introduced in January 1955, is a passenger car that was an evolution of the earlier Toyota SF/RH sedan (also known as the Super) with a modernized body. As with its predecessor, the Master has a ladder frame truck chassis with leaf sprung solid axles both at the front and the rear. The more conservative Master was sold in parallel with the first Toyota Crown as a frugally equipped and robust version meant for taxi usage. The Master and Crown shared the same R-series engine, which produces 48 PS (35 kW) in the Master. It was sold at a chain of Toyota Japan dealerships called Toyota Store, next to the more upscale Crown, which was intended as a private purchase alternative to the Master.
