The JAF Japan Formula 4 (JAF 地方選手権 F4 JAF Chihou Senshuken?) is a formula racing class in Japan. The class was founded in 1993 by the Japan Automobile Federation as a class between the FJ1600 and the All-Japan Formula Three Championship.


The Japanese Formula 4 is an open chassis class, open for all chassis manufacturers. Since 2012 the engines have a maximum capacity of 2,000cc. Currently the cars are allowed to be fitted with a Honda K20A, Toyota 3ZR or Nissan SR20 engine. Since 2010 the cars use a monocoque chassis in stead of a tube frame. In the first year of the monocoque chassis most cars were West Racing Cars.
