Having spent four seasons in GP2/F2 as a Honda junior, and then funding an additional campaign with his own money, Matsushita scored a total of seven wins in the Formula 1 feeder series, two of which came in feature races - including his final victory at Barcelona in 2020.
The 28-year-old has been a mainstay of the Super Formula grid since losing his F2 drive with MP Motorsport midway through the 2020 season, joining the minnow B-Max Racing team and delivering the squad a long-awaited first victory in the championship last month in wet conditions at Suzuka.
