Nick Cassidy has bagged a maiden Super Formula podium in Race 1 of Round 2 at Okayama, before finishing 11th in Race 2.
Cassidy qualified third for the opener and held the same position for the duration.
Race 2 was a far less straightforward affair even before it started as the New Zealander spun in qualifying and thus started from a lowly 17th position.
Cassidy suffered front wing damage at the start when he was caught up in an incident between other drivers.
The Kondo Toyota driver resumed 13th after his compulsory pit stop before gaining a position when Takuya Izawa crashed on his own, 13 laps from home.
The resulting Safety Car that compressed the field also helped Cassidy to gain one more position upon the restart.
“I'm over the moon with Saturday (Race 1), finishing on the podium in only my second race in Super Formula,” said Cassidy.
“(Sunday, Race 2) was frustrating with qualifying and then doing the whole race with a damaged front wing.”
Andre Lotterer won Race 1 and Yuhi Sekiguchi took out Race 2.
Cassidy is eighth in the standings, headed by Lotterer, with Round 3 at Fuji from July 8-9.

Formula Renault Eurocup
Will Palmer and Sacha Fenestraz have shared the race wins in Formula Renault Eurocup on the streets of Monaco, while Australian Alex Peroni is fifth in the points after a pair of sixth placings.
“The Saturday race showed how important it is to qualify at the top of the field at Monaco,” said Peroni, who all but maintained his starting position in both races.
“We'd improved the car's set-up and I was able to hold my position, but there was no way to overtake.
Palmer staved off an early challenge from Fenestraz to win Race 1, before the latter similarly led all the way in Race 2.
Luis Leeds recorded finishes of 14th and 11th, Zane Goddard 18th and 17th, and Thomas Maxwell 25th and 14th.
Round 5 sees three races run at the Hungaroring from Jun 30-July 2.
Matheus Leist has won the Freedom 100 on the Indianapolis Motor Speedway in flag-to-flag fashion.
Starting from pole, Leist led the field away but not a lap was completed before caution flags flew for a crash further back.
Aaron Telitz was on the way up when racing resumed, taking fourth from Neil Alberico on Lap 8, and then third from Zachary Claman De Melo on Lap 14.
By the end of Lap 19, Telitz had the leader Leist in his sights after passing Dalton Kellett for second, having ranged up on Kellett a second time.
Telitz got up on the outside of Leist on Lap 34 and ran side-by-side with the #26 Carlin Racing entry but lost momentum and instead ceded his own position to Kellett.
While Leist stayed just far enough in front to take win at the Brickyard in just his first race on an oval, while Telitz pipped Kellett for second at the finish line.
Leist's would be the first win for a #26 car at Indianapolis that weekend.
Kyle Kaiser held onto his series lead with a ninth-place finish ahead of a pair of races at Road America on June 24-25.

However, the man on the #1 Kawasaki hit back on the Sunday, heading up a podium of he, team-mate Sykes, and Ducati's Davies.

The Dutchman got the jump but then copped contact from Rob Huff, who looked for a Move at Turn 2.
Catsburg held on to the lead and gradually pulled away in his Volvo S60 to win by three seconds in the three-lapper on the 25.4km Nordschleife.
