Being backed by the three major automobile manufacturers in Japan, the driver of the series generally consists of the drivers graduating from the racing schools managed by those three, plus a number of privateers meeting the prerequisites.
To participate in the FCJ series, a driver needs to be younger than 26 years old and possess a National A racing license, but not having raced in Formula Three or above to participate, with a year's subscription fee of around 7.5 million yen. Despite being a series primarily catering the upcoming Japanese drivers, as of 2009 there were foreign drivers competing in the series.
The cars are open wheelers, running on a Tatuus chassis  and is mated to a 2.0 L 200 hp engine and a six-speed sequential gearbox, similar to a Formula Renault 2.0 car. The engine is a Renault F4R unit badged as FCJ and maintained by Nismo. The tires are manufactured by Dunlop. To ensure parity of the cars, the engine and gearbox are both sealed prior to being delivered to the competitors so that no private tuning could be carried out in between. Moreover, the cars are centrally maintained by the organizers for this purpose.
