Season report
Nine cars entered the season opener at Fuji Speedway, where Bionic Jack's Sota Ogawa took pole positions for all three races. HELM's Yuya Hiraki started race one by taking the lead, and the pair fought all race long, with the latter coming out in front at the end. Sutekina's Ryunosuke Sawa stalled at the start, but managed to recover to third place. The second race saw Ogawa run off track at the start and rejoining fourth. Sawa benefitted to take the lead and the win. Ogawa was able to climb back to second place, with Hiraki completing the podium. The third race finally saw Ogawa able to convert a pole position into a win, as his teammate Yugo Iwasawa, who started alongside him, was unable to keep up. He fell back throughout the race, allowing Sawa and Hiraki onto the podium. Ogawa left Fuji with a three-point championship lead over Sawa.

The grid shrunk to seven cars at Suzuka Circuit as PONOS Racing's Kazuki Oki and Ogawa shared pole positions. The track was hit by a huge weather front for race day, causing torrential rains. The first race saw three laps of safety car conditions, before race control declared the conditions as too dangerous and waved the red flag. The race was not restarted, allowing Oki to take an uncontested win ahead of Ogawa and Sutekina's Liam Sceats. The second race later in the day was not much better: even through the race was started under green flag conditions, they only lasted for a single lap before Sutekina's Kaleb Ngatoa went off. The ensuing safety car turned into a red flag that ended the race, with Ogawa the one to take the win ahead of Sceats and Iwasawa. Both races were awarded half points, with Ogawa now 24.5 points ahead of the absent Sawa.

Round three at Okayama saw Ogawa sweep qualifying for all three races once again. After fending off Sceats at the start of race one, he was free to lead the whole race and take the win. Sceats was unable to muster an attack on the lead, before he dropped back behind Iwasawa and Sutekina's returning category veteran Yu Kanamaru. The second race saw Ogawa build a gap right from the start, but Kanamaru was the fastest car. The latter started fifth, but once he got into third, he caught the leaders by several seconds per lap. He passed his teammate Jiei Okuzumi on lap twelve and took the lead on lap 16 to win. Sceats overtook Ogawa at the start of the third race and held on to become the first foreign race winner in championship history and move into second in the standings, 56 points from Ogawa. Kanamaru ended his weekend with another podium.

The second half of the season began at Motegi, where Ogawa was once again unbeaten in qualifying. He gapped the field through the first half of race one, before making a mistake that saw him run into the gravel and retire. This promoted Okuzumi in the lead, and he won the race ahead of TOM'S's Formula Regional debutant Enzo Trulli and Sceats. Trulli put pressure on Ogawa all throughout the second race despite having a poor start. His efforts culminated in a photo-finish that saw Ogawa win by 0.010s, with Okuzumi further behind in third. The last race began with a five-car battle for the lead that saw Ogawa run into the gravel again. This time though, he was able to fight his way back into second, ahead of Trulli, while Sceats took the win. This saw Ogawa's lead being reduced for the first time of the season, with his advantage now at 47 points.

Eleven cars turned up when the series supported the 6 Hours of Fuji, and Sawa and Ogawa shared pole positions for the two races. As were both qualifying sessions, the first race was held on a wet track. Ogawa overtook Sawa for the lead at the start and continued in first place until he had to lap backmarker traffic through the second half. This brought Sawa back into contention, and as rain then started to fall, he got into the lead and won. Sutekina's Mizuki Ishizaka completed the rostrum. Race two saw the grid take on a foggy and rainy track. Both Ogawa and Sawa went off, with the former doing so two times and having to retire after his second mistake. This promoted Sceats to the front and allowed him to win ahead of Ishizaka and Sawa. Ogawa's championship lead was reduced once again and now stood at only 28 points.

The final round of the season at Sugo saw the grid reduced back to nine entries, with two of them unable to qualify. All three pole positions were earned by foreign drivers, with Trulli and Bionic Jack's Michael Sauter on top. The first race began with another bad start for Trulli that saw him drop behind Sauter. The latter then had to concede the lead to Okuzumi while the Italian crashed and retired. Sauter retook the lead from Okuzumi and came first, but a penalty dropped him to fourth, behind Sceats and Ogawa. Six cars started the second race that saw polesitter Sauter drop to fourth right at the start, before eventually having to retire. Okuzumi led Oki and Sceats home, with the latter keeping the championship open into the final race. That was won by Sauter, ahead of Okuzumi and Oki, while Ogawa came fourth ahead of Sceats to win the championship.

While Sauter, Trulli and Sceats became the first foreign drivers to contest multiple rounds in the history of the championship, the series still struggled heavily to attract competitive entries. Only two drivers contested the full season, and only six drivers entered more than two rounds. Ogawa became champion in his third year in the championship, by virtue of being the only driver with previous knowledge of both the car and the tracks that contested all rounds.
