Saito set the pace in qualifying with a 1:44.369, edging Kokoro Sato by just 0.068 seconds. Miki Onaga completed the top three. Saito carried that advantage into the Sprint Race, holding off Sato through the opening stages as the battle behind them developed. Rio Shimono and Joanne Ciconte collided at Turn 8, ending Shimono's race with front-wing damage. Onaga briefly moved ahead of Sato for second on Lap 9, but Sato reclaimed the position at Turn 3.
Saito went on to win the Sprint Race, finishing 4.077 seconds ahead of Sato, with Onaga third. Riona Tomishita, one of Saito's title rivals, finished fourth. The result moved Saito two points clear at the top of the championship standings heading into the Final Race.
Starting from pole again, Saito made a clean getaway in the Final. An opening-lap spin for Paige Raddatz at the hairpin and a broken front wing for Itsumo Shiraishi on Lap 2 brought out the safety car. Racing resumed on Lap 6, with Sato attempting to challenge Saito for the lead, but the championship leader held her position.
Saito completed the weekend with a second victory, 1.719 seconds ahead of Sato. Onaga again finished third, while Tomishita took fourth ahead of Ai Miura, Sara Matsui, Shimono, Mako Hirakawa, and Kilei Kanemoto. Marie Iwaoka completed the top ten and claimed the final point.
Joanne Ciconte, who entered the round second in the standings, left Fuji without scoring and dropped to fifth overall. Aimi Saito finished the season on 102 points to claim the championship, with Kokoro Sato runner-up on 89 and Riona Tomishita third on 88. Saito's Fuji sweep delivered a second KYOJO Cup title and the strongest possible finish to the campaign.
