The HiAce was primarily designed as a commuter vehicle, able to transport up to 8 people. With this goal in consideration, the HiAce exterior dimensions and engine displacement were in compliance with Japanese government regulations so as to encourage sales, and accommodate the most passengers by utilizing a cabover body style, with the engine installed underneath and between the front passengers. It was a smaller alternative to the larger Toyota Coaster minibus, and was introduced to Japan after the 1950 Volkswagen Transporter, and the 1961 Chevrolet Greenbrier cabover vans. It was introduced in the same year as the much smaller Toyota MiniAce, which was based on the Toyota Publica, a predecessor to the Toyota Corolla.
