The 2023 Eneos Super Taikyu Series Supported by Bridgestone (previously the Eneos Super Taikyu Series Powered by Hankook) was the thirty-third season of the Super Taikyu Series endurance racing championship. The season started on 19 March at Suzuka Circuit and ended on 12 November at Fuji Speedway.
Zhongsheng ROOKIE Racing won the championship in the series' GT3 category, known as ST-X, with a Mercedes-AMG GT3.
A specially designed Toyota GR Corolla running on liquid hydrogen fuel made its debut at the NAPAC Fuji SUPER TEC 24 Hours Race on 27–28 May.
Calendar The Super Taikyu Series announced their provisional 2023 calendar on 24 October 2022, with seven rounds held at the six major Japanese racing circuits. The final round of the season was moved from Suzuka Circuit to Fuji Speedway. Before the start of the season, the sixth round at Okayama International Circuit was moved from 15 October to 22 October to avoid a clash with the Super GT Series' race at Autopolis, and the seventh round at Fuji was moved from 19 November to 12 November, to avoid a clash with the World Rally Championship Rally Japan. +RoundEventRace LengthRace FormatClassesCircuitDate1Suzuka Super Taikyu 5 Hours Race5 hours1 raceAllSuzuka Circuit18–19 March2NAPAC Fuji SUPER TEC 24 Hours Race24 hours1 raceAllFuji Speedway26–28 May3SUGO Super Taikyu 3 Hours Race3 hours 2 racesST-X / Z / TCR / Q / 1 / 2 / 4 / 5Sportsland Sugo8–9 July4Super Taikyu Race in Autopolis5 hours1 raceST-X / Z / TCR / Q / 2 / 3 / 5Autopolis29–30 July5Motegi Super Taikyu 5 Hours Race5 hours1 raceST-X / Z / TCR / Q / 1 / 2 / 3 / 4Mobility Resort Motegi2–3 September6Super Taikyu Race in Okayama3 hours x 22 racesST-X / Z / TCR / Q / 1 / 3 / 4 / 5Okayama International Circuit21–22 October7S-Tai Final Fuji 4 Hours Race with Fuji Niq Festival4 hours1 raceAllFuji Speedway11–12 November
Tyres Hankook entered 2023 in the final year of a three-year contract as the Super Taikyu Series' official tyre supplier. On 12 March, a fire at Hankook's plant in Daejeon forced the company to halt all production at the facility, including the production of tyres supplied to Super Taikyu.
Bridgestone agreed to become the new tyre supplier to the series with immediate effect on 24 April, just 12 days after signing a new three-year deal to become the series' new tyre supplier in 2024. At the NAPAC Fuji SUPER TEC 24 Hours Race, most teams were supplied with Bridgestone slick tyres and the remaining stock of wet tyres from Hankook. This excluded ST-4 and ST-5 class entries, and select ST-Q cars, which used Bridgestone high-performance street tyres instead of slicks. Bridgestone would then supply wet racing tyres from the third round onwards.
At the fourth round in Autopolis, it was confirmed that the ST-4, ST-5, and select ST-Q cars would continue to race on Bridgestone street tyres for the remainder of 2023.
Teams and drivers On 19 February, the Super Taikyu Series published their provisional full-season entry list, featuring 62 entries. 61 different cars entered throughout the course of the season.
