The F4 Japanese Championship (ＦＩＡ－フォーミュラ４ 地方選手権, FIA F4 Chihou Senshuken)[1] is a formula racing series held in Japan regulated according to FIAFormula 4 regulations. The inaugural season was held in 2015.
History
Gerhard Berger and the FIA Single Seater Commission launched the current FIA Formula 4 in March 2013.[2] The goal of FIA Formula 4 was to make the ladder to Formula 1 more transparent. Besides sporting and technical regulations, costs are regulated too: Any eligible car may not exceed a purchase price of €30,000. A single season in Formula 4 may not exceed €100,000 in costs.
The F4 Japanese Championship was launched by the GT Association on 16 December 2014, as one of the second phases of Formula 4 championships to be launched following the Italian F4 Championship and Formula 4 Sudamericana which launched in 2014.[1] All rounds are support events to the Super GT Series.
Japanese race car constructor Dome was contracted to design and build the spec F110 chassis.[1] The cars are constructed out of carbon fibre and feature a monocoque chassis. The engine is a 2.0-litre TOM'SToyota inline-four. Dunlop (Sumitomo Rubber Industries) is the tyre supplier.
The series is open to drivers aged 16 and up.[3] While primarily contested by young drivers moving up the single-seater ladder, older amateur drivers also compete in the series in the Independent Cup category.
A second-generation F4 Japanese Championship car built by Toray Carbon Magic, called the MCSC-24, was first revealed in 2022 and will debut in 2024, with an integrated halo safety device and a more powerful TOM'S Toyota engine.[4]
