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 FIA Formula 4 regulations.

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.

[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.
