Sena Sakaguchi set a new lap record of 1m09.627s aboard the Yokohama-shod #19 Toyota GR Supra, breaking the three-year old benchmark held by Honda’s Koudai Tsukakoshi.
That was despite Sakaguchi being held up in the final part of the lap by the Nakajima Racing Honda of Takuya Izawa, who was summoned to the stewards for rejoining the track dangerously after an off at SP Corner.
Toyota secured a front-row lockout courtesy of Yuji Tachikawa in the Cerumo GR Supra, which was 0.378s behind the Bandoh car in second.
Nissan’s flagship NISMO Z qualified third in the hands of Tsugio Matsuda, 0.422s off the pace, but will drop to seventh owing to a four-place grid penalty.
This was incurred by Matsuda for accumulating seven penalty points, having crossed the threshold when Kazuki Hiramine’s Impul Nissan off the road during their battle for second in last month’s fifth round at Suzuka.
That promotes the Team Kunimitsu Honda NSX-GT, in which Naoki Yamamoto set the fourth-fastest time, to third on the grid, the best of the cars carrying a fuel flow restrictor this weekend.
Of the three cars carrying stage two fuel flow restrictors, only the Real Racing Honda made it out of Q1, with Nobuharu Matsushita qualifying fifth and being promoted to fourth on the grid by Matsuda’s penalty.
Yuichi Nakayama (SARD Toyota) and Ukyo Sasahara (Mugen Honda) move up to fifth and sixth, while Izawa was eighth in slowest in the Q2 pole shootout after his off.
Sasahara's team-mate Toshiki Oyu had previously set a new lap record in Q1, which was later beaten in the second session by Sakaguchi on his way to pole position.
The #37 TOM’S Toyota and #3 NDDP Racing Nissan will start 10th and 11th respectively with their stage two restrictors after dropping out in Q1.
After its win last month at Suzuka, the points-leading Impul Nissan, the only car in the field with the stage three fuel restrictor, was 14th in the hands of Hiramine.
Starting from the back of the GT500 grid will be the #36 TOM’S Toyota of Sho Tsuboi and Giuliano Alesi, which failed to set a time in Q1 after running into mechanical issues.
K-tunes Racing scored pole position in the GT300 class with veteran driver Shinichi Takagi setting the top time of 1m17.373s aboard the team’s Lexus RC F GT3.
Takagi’s time was enough to take the top spot by an impressive margin of 0.318s ahead of the works Subaru BRZ of Hideki Yamauchi.
The points-leading Kondo Racing Nissan GT-R NISMO GT3 of Kiyoto Fujinami and Joao Paulo de Oliveira, which is still carrying the maximum 100kg of success ballast, qualified ninth in the hands of Fujinami but will start 13th owing to de Oliveira’s four-place grid drop - the Brazilian having also amassed six penalty points.
