Both class championships were won by Toyota teams driving the respective GT500 and GT300 versions of the Toyota GR Supra.

Regulation changes

GTA chairman Masaaki Bandoh outlined the series' environmental initiative plans in November 2022, known as the "Super GT Green Project 2030". The series aims to reduce carbon emissions by 50 percent by 2030. As part of this initiative, Super GT made the following regulation changes for 2023:

* Super GT debuted a new, 100 percent sustainable carbon-neutral fuel manufactured by ETS Racing Fuels, a division of Haltermann Carless GmbH. The new ETS Renewablaze GTA R100 racing fuel was introduced to GT500 for the first round of the championship. The GT300 class will continue to use petroleum fuel for the season after feedback gathered in testing.
* The number of tyre sets available to teams per race weekend has been limited to five sets of dry tyres and six sets of wet tyres for 300 kilometre race meetings, one set fewer for each than in 2022. The number of tyre sets available for 450km races would be determined on a case-by-case basis. Ultimately, there would be six sets of dry tyres and seven sets of wet tyres available at all five 450km races, one set fewer for each than in 2022.

Teams and drivers

On 20 February, 2023, the GTA released the series entry list, featuring 15 entries in the GT500 class and 27 entries in the GT300 class. All teams compete under a Japanese license.
