Micro MAX produced two contrasting stories. Round 3 saw Takao Kunbo emerge from a tightly contested weekend to claim victory ahead of Hugo Liang and Haruki Ikemi after neither qualifying polesitter Rui Mikami nor heat winner Minato Mori could convert their pace into the final win. Round 4 belonged to Takaharu Murakami, who qualified on pole and recovered from two runner-up finishes in the heats to take victory in the Final ahead of Mori and Mikami.
Mini MAX also delivered different winners across the two rounds. Tomoya Onishi turned consistent front-running pace into victory in Round 3 after sharing heat wins with Daniel Yoon, eventually leading Yoon and George Xia in the Final. Round 4 saw Aito Yokoi take over at the front. After qualifying on pole and winning two of the three heats, Yokoi secured the Final victory ahead of Onishi and Yoon to complete one of the most complete performances of the weekend.
Junior MAX featured one driver who consistently rose to the occasion. Takeru Shibazaki was among the quickest drivers throughout both rounds, winning Round 3 ahead of Juki Hayashi and Takeshi Niihashi before backing it up in Round 4 with another victory over Yukinaga Fujiwara and Niihashi. Across both weekends, Shibazaki combined qualifying pace, heat wins, and racecraft to establish himself as the category's standout performer.
Senior MAX delivered a changing cast of contenders. Round 3 saw Shogo Endo secure victory after sharing the heat wins with Ayumu Senda and Koshin Kusumoto, eventually finishing ahead of Senda and Timofey Degtyarev. Round 4 shifted the balance as Kusumoto completed a strong recovery from the heat stages to win the Final ahead of Akinori Kikuchi and Shun Sekiguchi in a race heavily affected by post-race penalties and exclusions.
MAX Masters also produced different stories across the two rounds. Kazuma Kimura dominated much of Round 3, winning two heats before taking victory in the Final ahead of Gaku Yamazaki and Kengo Sugiyama. Round 4 belonged to Junji Okamoto, who converted consistent podium finishes through the heats into a Final win ahead of Kenjin Watanabe and Kimura after several post-race penalties reshuffled the order behind him.
With six categories competing across two rounds and numerous penalties influencing the final classifications, Mizunami once again highlighted the depth and competitiveness of Japan's Rotax paddock. As the championship moves forward, Shibazaki's Junior MAX form and the increasingly competitive battles in Senior MAX and Masters suggest the title fights remain far from settled.
