The 2025 Suzuka 1000 km took place on 14 September 2025 at the Suzuka Circuit in Suzuka, Japan. It was the 49th edition of the Suzuka 1000km, the fourth round of the 2025 Intercontinental GT Challenge, and the first after a five-year hiatus due to the effects of the COVID-19 pandemic.

Entry list A provisional entry list was announced on 18 July, featuring 30 entries. Eight manufacturers were represented: 11 Porsche cars (10 Porsche 911 GT3 R (992) and 1 Porsche 911 GT3 R (991.2)), 7 Mercedes cars, 4 Ferrari cars, 3 Corvette cars (2 Chevrolet Corvette Z06 GT3.R and 1 Callaway Corvette C7 GT3-R), 2 Nissan cars, and 1 car each from Audi, BMW, and Lamborghini.

An updated list was revealed on 18 August, with the grid expanded to 33 entries. Team WRT entered with two BMW M4 GT3 Evos, plus K-tunes Racing with their Ferrari, and RunUp Sports' Nissan. The only Lamborghini dropped off the grid after Absolute Racing switched its Huracán GT3 EVO2 to a Porsche 911 GT3 R, while Herberth Motorsports' second Porsche withdrew.

Super GT teams were allowed to enter GTA-GT300 regulation vehicles after an agreement between SRO and the GT Association (GTA) was reached in late 2024. However, no GTA-GT300 cars entered the race.
