In the FIA-F4 Champions Class, qualifying belonged entirely to TGR-DC RS F4. Sakai Ryu secured pole for both rounds, with teammate Muto Masana alongside him and Igarashi Buntaro completing a full team lockout of the top three in both sessions.
Round 1, however, quickly evolved into a race of attrition and penalties. While Sakai initially controlled proceedings, two separate five-second penalties for off-track safety violations and contact after running wide dropped him down the order. That opened the door for Igarashi Buntaro to secure the opening victory, with Kumagai Taito finishing second for OTG DL F4CHALLENGE and Momose Sho completing the podium for HFDP with B-Max Racing Team.
Round 2 delivered another reshuffled result. This time, Muto Masana converted front-running pace into victory, giving TGR-DC RS F4 its second win of the weekend. Nakai Hideto secured second for JMS RACING with B-MAX, while Igarashi added another podium in third. Sakai’s weekend unravelled further after a pit lane speed violation triggered a drive-through and subsequent 40-second penalty, removing him from contention despite his qualifying dominance.
The FIA-F4 Independent Class saw far greater stability at the front. Toriba Yutaka established himself as the benchmark from the outset, taking pole for both rounds and converting that pace into back-to-back victories for Kageyama HYDRANGEA MCS4.
In Round 1, Toriba led home Imada Nobuhiro and Hirobon, while Round 2 saw Ikari and Oyama Masayoshi complete the podium. Several post-race penalties reshaped the lower order, including a disqualification for Kojima Kentaro after failing to acknowledge a drive-through penalty.
Across both classes, Fuji’s opening weekend established clear pace-setters but also highlighted how quickly penalties can overturn raw speed. TGR-DC RS F4 leave with the Champions Class momentum, while Toriba Yutaka exits Round 2 as the early Independent Class benchmark.
