Seventeen cars lined up for Saturday's Race 6, with persistent rain leaving the 4.801-kilometre Motegi circuit wet throughout the weekend. Omiya converted pole position into a commanding lights-to-flag victory, finishing 14.590 seconds ahead of teammate Ryota Horachi to secure a PONOS RACING one-two. Muto completed the podium for TOM'S TGR-DC FR, followed by Rio Shimono, Yuzuki Miura, and Lin Chenghua.
Sunday's Race 7 delivered a much closer fight at the front. Muto started from pole with Omiya alongside on the front row, but Omiya found a way through during the race and controlled the closing stages to secure his second win of the weekend. Muto crossed the line just 0.903 seconds behind, with Horachi completing another podium finish in third. Miura, Shimono, and Yu Oda rounded out the top six, separated by just over five seconds at the flag. Lin Chenghua did not start the race.
The Masters Class also produced contrasting results across the two races. Hideaki Irie led the category in Race 6 ahead of Masayuki Ueda and Shoichiro Akamatsu, while Akita finished fourth in class. Race 7 saw the order change, with Akita taking class honours after finishing seventh overall. Ueda and Akamatsu completed the Masters podium, while Irie dropped to fourth following a post-race penalty.
Omiya leaves Motegi with maximum points after converting pole into victory on Saturday and fighting through from second on the grid to win again on Sunday. Muto's pace across the weekend and Horachi's consistency kept the pressure on, while the Masters battle added another layer to an event shaped by changing fortunes in challenging conditions as the championship moves on to Round 4.
