The 2025 Japanese Super Formula Championship is scheduled to be the fifty-third season of premier Japanese open-wheelmotor racing, and the twelfth under the moniker of Super Formula. The season will start in March at Suzuka Circuit and is due to be contested over 12 rounds in seven race weekends, ending in November at Suzuka.[1]
Teams and drivers
All teams used identical Dallara-built SF23 chassis with either Honda or Toyota engines. Every Honda-powered car used a Honda HR-417E engine and every Toyota-powered car used a Toyota TRD-01F engine.
The entry co-run by Inging Motorsport and Cerumo added another title sponsor alongside Vertex Partners, with Industrial manufacturer Sanki Shokai joining the series and the team competing under the name Sanki Vertex Partners Cerumo・INGING.[4]
TGM Grand Prix changed both their name and their engine supplier. The team will no longer run Honda engines and instead now join ROOKIE racing in serving as Toyota Gazoo Racing's junior team, TGR-DC. The team also acquired a new title sponsor in telecommunications operator KDDI, with the team entering the 2025 season under the name KDDI TGMGP TGR-DC.[2]
Team Impul will have an all-new line up as 2016 series championYuji Kunimoto retired from the series after 14 seasons and neither of the four drivers who drove the No. 19 car in 2024 returned.[6] The team signed Oliver Rasmussen, who came 19th in the WEC's Hypercar class with Jota Sport in 2024 and will make his series debut, and NISMO works driver Mitsunori Takaboshi, who will make his full-season debut after a one-off Super Formula appearance for Team Impul in 2021.[2]
Newly rebranded team TGMGPTGR-DC also took on two new drivers as Juju Noda and Hiroki Otsu both left the team following its switch from Honda to Toyota engines. Kazuto Kotaka joins the team after coming 14th with Kondo Racing in his second Super Formula season in 2024. Hibiki Taira, who drove Team Impul's No. 19 car on four occasions in 2024, will complete TGMGP TGR-DC's lineup on his full-time debut in the series.[2]
Race calendar
The provisional calendar was announced on 1 August 2024.[1] All weekends except the ones at Autopolis and Sportsland Sugo will be double-headers, making this the longest calendar in Super Formula history. The series originally planned its first race outside Japan since 2004 with a round held at Inje Speedium.[8] These plans, however, were cancelled in October 2024. It marked the second time that a planned round at Inje was cancelled.[9]
