Race calendar and results
edit
All rounds were held in Japan and support the Super GT events.[1][8] The revised calendar was published on 10 February 2021.[9] The second round of the championship at Suzuka Circuit was postponed from 29–30 May to 21–22 August due to COVID-19 pandemic. The nomenclature was kept, despite the round at Twin Ring Motegi being held in the meantime.[10][11]
