Formula Beat, known as JAF Japan Formula 4 (JAF 地方選手権 F4, JAF Chihou Senshuken) until its rebranding in 2023, is a formula racing class in Japan. The class was founded in 1993 by the Japan Automobile Federation as a class above FJ1600 and below the former All-Japan Formula Three Championship and the current Formula Regional Japanese Championship and Super Formula Lights.

Car
editFormula Beat is an open chassis class, open for all chassis manufacturers. Since 2012 the engines have been limited to a maximum capacity of 2,000cc. Currently the cars are allowed to be fitted with a Honda K20A, Toyota 3ZR or Nissan SR20 engine. In the early 2010s, most cars were primarily built by Japanese constructor West Racing Cars, but the championship has since seen entries from older Dallara-built Formula 3 cars and Tatuus chassis.
