atsumasa Chiyo is one of Japan?s most accomplished GT racing drivers, internationally recognised for his victories in some of the world?s most prestigious endurance races.
He first gained international attention in 2015 when he delivered a dramatic victory at the Bathurst 12 Hour, overtaking two competitors during the final safety car restart with only minutes remaining. In the same season, he became the first Japanese driver to win the Blancpain Endurance Series Pro Cup Championship and also secured the SUPER GT GT300 Team Championship.
Born in Tokyo, Japan, Chiyo began karting at the age of 15. Despite starting later than many of his peers, he quickly progressed through the ranks after being selected for Nissan?s Driver Development Program in 2007. His talent and determination led him to win the Japanese Formula 3 Championship in 2011 before establishing himself as one of Nissan?s leading GT racing drivers.
Since joining Nissan?s factory programme, Chiyo has competed at the highest levels of Japanese and international motorsport, including SUPER GT GT500, Super Formula, Intercontinental GT Challenge, Blancpain GT Series, Nürburgring 24 Hours, and the Bathurst 12 Hour.
In SUPER GT GT500, Chiyo has become a key figure within Nissan?s flagship motorsport programme. Following the introduction of the Nissan Z GT500 in 2022, he secured two race victories and finished runner-up in the championship. Throughout his career, he has consistently delivered race wins, podium finishes, and championship contention while representing Nissan and NISMO at the highest level. Today, Chiyo is Nissan?s lead factory driver in SUPER GT GT500, continuing to pursue victories and championship success on the world stage.
