Masaki Jyonai (城内政樹, Jōnai Masaki, born 9 September 1962)[1] is a Japanese racing driver and businessman.

Racing career

Jyonai started karting in 1988; he is noted for his extensive experience in kart racing, having won numerous karting championships. He moved to car racing in 1993, racing in the Suzuka 1000 km in the Proto 2 class; he won on his debut.[2]

Jyonai began competing in Super GT in 1997 with the SigmaTec Racing Team. As of 2023, he has won two races;[2] his best finish in the championship is 5th, achieved in his first year in the series. Outside of racing, Jyonai is the CEO and President of Marusho Co. Ltd., a company involved in the lighting, security and construction sectors.[3] He is also a lecturer at the karting classes of Honda Racing School Suzuka as well as a color commentator for various television programs.

He occasionally competes using the pseudonym Guts Jyonai (Guts城内, Gattsu Jōnai);[2] Jyonai says he took the name from comedian Guts Ishimatsu. In more recent years he has reverted to using his real name.[1]
