The Datsun Roadster was a lightweight automobile produced by Nissan in the 1930s. The series was a predecessor to the Fairladysports cars, and was an example of the earliest passenger cars produced in Japan.
The Roadster was replaced for 1935 by the Road Star. It used a 14 hp (10.4 kW) 722 cc engine, and a Coupe model was also available. The engine's output was pushed to 16 hp (12 kW) for 1937. Production ended with Japan's entry into World War II in 1941.
