Super Taikyu Series

Super Taikyu (スーパー耐久, Super Endurance), formerly known as the Super N1 Taikyu Series prior to 2005 and N1 Endurance Series prior to 1995, and currently named the Eneos Super Taikyu Series Supported by Bridgestone for sponsorship reasons, is a Japanese endurance racing series that began in 1991. In contrast to the Super GT Series, the Super Taikyu Series is a pro-am racing series for commercially available racing vehicles such as GT3, GT4, and TCR cars, and minimally-modified production vehicles mainly from the Japanese domestic market.

Super Taikyu races are held across all of Japan's major motor racing circuits, with formats including a single five-hour race, and a double-header format of two three-hour races. The series' largest event is the Fuji Super TEC 24 Hours, which is held annually at Fuji Speedway since its revival in 2018. Prior to that, the Tokachi 24 Hours was the series' largest event, held annually from 1994 until 2008.

In 2022, Eneos became the new title sponsor of the series.
