Mugen driver Nojiri came out top in a tense late duel with Saturday race winner Ryo Hirakawa (Impul) to take the chequered flag by a margin of 1.6 seconds for his seventh career win, giving himself the championship lead.
Ritomo Miyata completed the podium for TOM'S in third place, less than a second behind Hirakawa.
While Nojiri made a clean getaway from pole to maintain the lead early on, ahead of fellow front-row starter Miyata, his Mugen team-mate Ukyo Sasahara was left stranded on the grid for the second time in two days.
An early safety car period was called when Nobuharu Matsushita pitched Tadasuke Makino into a spin at Turn 10 on the opening lap, an incident that put Dandelion driver Makino out of the race.
Nojiri maintained the advantage over Miyata when the race resumed on lap 5 of 41, with Kenta Yamashita running third ahead of Kamui Kobayashi, Fenestraz and Hirakawa.
Fenestraz dropped to the rear of the pack with a spin, briefly promoting Hirakawa to fifth before he lost a spot to star Team Goh rookie Atsushi Miyake.
Kobayashi was first of the frontrunners to pit when the window opened on lap 10, with Hirakawa settling into fourth place after he had succeeded in repassing and dropping Miyake.
Yamashita was next in the pits of the lead group on lap 19, followed by Miyake on lap 20, giving Hirakawa some crucial time in clear air before he made his stop on lap 22.
That allowed the Impul driver to undercut Miyata, who brought his TOM'S car in the pits on lap 24, with Nojiri following suit one lap later.
However, there was nothing Hirakawa could do about Nojiri in the closing stages, with the gap between the lead pair remaining mostly static at around 1.5s, and Miyata staying close to Hirakawa but never enough so to attempt an overtake - with the top three finishing in that order.
Yamashita brought home his Kondo Racing car in fourth ahead of Miyake, while Yuhi Sekiguchi made a late-stopping strategy to work to finish sixth in the second Impul machine, up 10 places from his grid position.
Hiroki Otsu (Dandelion) and Giuliano Alesi (TOM'S) were seventh and eighth, having both been among the early stoppers, while Kobayashi (KCMG) spent the latter half of the race engaged in a pulsating duel with a recovering Sasahara, finally hanging on for ninth ahead of the Mugen driver.
