F4 Japanese Championship

The F4 Japanese Championship, inaugurated in 2015, is a premier formula racing series in Japan, adhering to FIA Formula 4 regulations. Serving as a crucial platform for young drivers transitioning from karting to higher tiers of motorsport, the championship has been instrumental in developing talents such as Yuki Tsunoda, who clinched the title in 2018 before advancing to Formula 1. The series typically comprises multiple rounds held at renowned circuits across Japan, including Fuji Speedway, Suzuka Circuit, and Mobility Resort Motegi, often supporting Super GT events. In 2024, the championship introduced the second-generation MCSC-24 chassis, constructed by Toray Carbon Magic, and the TOM'S TMA43 engine, producing 180 horsepower, enhancing both performance and safety standards. The 2025 season marks the eleventh iteration of the championship, continuing its tradition of nurturing emerging driving talents.
