Red Bull Formula 1 junior Pierre Gasly claimed his first Super Formula victory at Motegi on Sunday.
Gasly followed in the footsteps of his predecessor as GP2 champion Stoffel Vandoorne by moving to the Japan's premier category Super Formula after his title win in the F1 feeder series.
He arrived at this weekend's Motegi round eighth in the championship, having taken a best result of fifth in the last event at Fuji.
Gasly qualified his Team Mugen car fourth at Motegi but moved up to second by running long before his pitstop and vaulting Kenta Yamashita and Tomoki Nojiri.
He then gained the lead when Toyota LMP1 racer and sometime F1 driver Kamui Kobayashi lost half a minute with a problem on his right rear wheel at his pitstop.
That handed Gasly a 15-second advantage, which he protected on the way to his first SF win and the first for a Honda-powered driver since Vandoorne's triumph in the 2016 season finale at Suzuka.
Two European drivers were on the podium, with Formula E racer and 2015 European Formula 3 champion Felix Rosenqvist resisting championship leader Hiroaki Ishiura for third.
