The 2025 Japanese Super Formula Championship is the fifty-third season of premier Japanese open-wheel motor racing, and the twelfth under the moniker of Super Formula. The season started in March at Suzuka Circuit and is due to be contested over 12 rounds in seven race weekends, ending in November at Suzuka. [1]
Vantelin Team TOM’S driver Sho Tsuboi entered the season as the defending champion.

Double-header race weekends now have two 60-minute practice sessions on a Friday instead of a single 90-minute session. The rounds held at Autopolis and Sugo retain the format previously employed for single-race events, with 90 minutes of practice prior to qualifying on Saturday. Races held on Saturday are now run over a reduced distance of 165km, while races held on Sunday, including those held during the single-race weekends at Autopolis and SUGO, are run over 185km. These longer races no longer have a pre-determined pit window, while the shorter races retained the existing pit window. [25]
A restriction on the teams' activity on race weekends was employed in order to prevent fatigue among staff members. Teams are now required to stop all work carried out in the paddock four hours after the end of the final session, although there are exemptions in cases of cars becoming seriously damaged in incidents. [25]
On October 27, 2025, the Suzuka schedule was changed to accommodate the three-race format. Qualifying sessions for both afternoon races will be held on Saturday morning. The Saturday race and Sunday afternoon races will retain their standard distances. The Sunday morning race, which is the postponed Fuji race with the grid set by the results of qualifying at Fuji for Round 10, is scheduled for 19 laps (110km) with a 50 minute time limit, and no pit stops scheduled.
