A grid of 42 cars marks a reduction of one car compared to last season, although there was only one race, May's Fuji 450km, in which all 43 cars initially entered for the 2022 campaign actually took part.
As has been the case in recent years, Toyota has the most cars entered in the GT500 class with six GR Supras split between five teams, while Honda fields five cars and Nissan four.
