The Toyota Dyna is a medium-duty cab over truck for commercial use. In the Japanese market, the Dyna is sold alongside its twin called the Toyoace. The Toyoace was a renaming of the Toyopet SKB Truck as a result of a 1956 public competition with 200,000 entries. "Dyna" is short for dynamic.
The Dyna was originally available in Japan only at Toyota Diesel Store locations, then later available at Toyota Store locations, while the Toyoace twin was available at Toyopet Store locations. The Dyna was also sold as the Japanese: Daihatsu Delta and the Hino Dutro.
In Japan, its traditional competitors are the Isuzu Elf, the Mitsubishi Fuso Canter and the Nissan Atlas.
The former Central Motors produced the Dyna Route Van from April 1957 to June 1967
