[13] After losing his backing from Renault, Fenestraz moved to Japan to contest the Japanese Formula 3 Championship with B-Max Racing with Motopark.

[17] He continued to compete with Kondo Racing, but could only drive in the last three rounds given that Fenestraz had been unable to enter Japan because the government had closed its borders due to the pandemic.

Fenestraz continued racing with the same team, but this time he had his best season in Super Formula, where he clinched his maiden win in Sportsland SUGO, and adding a couple of podiums to his name.

In addition to his 2019 Japanese Formula 3 campaign, Fenestraz also partook in the GT300 class of the Super GT championship with Kondo Racing, finishing sixth overall.

[15] The following year, Fenestraz graduated to the GT500 class with Lexus rebranded Toyota Gazoo Racing replacing Kazuki Nakajima at TGR TOM'S au and partnering Yuhi Sekiguchi.

[22] In August 2022, Fenestraz made his Formula E debut in the second Seoul ePrix, replacing Antonio Giovinazzi who suffered a hand injury in the previous race.

[24] The year began promisingly, with the Frenchman getting into the knockout stage of qualifying for the season-opening Mexico City ePrix, although he would fall back during the race.

[26] The French driver qualified in fourth for the Hyderabad ePrix two weeks later, but would miss out on a chance at points after becoming stuck between the two Jaguar Racing cars, which had crashed just in front of Fenestraz.

[27] During the following round in Cape Town, Fenestraz took his maiden pole position in the series, beating Maximilian Günther in the final stage and setting the fastest ever Formula E lap in the process.

[28][29] During the race however, Fenestraz fell down to third before being collided into by Nick Cassidy on the final lap, hitting the barriers which would result in a 14th-placed finish.
