seven x seven Racing's Taichi Watarai completed the Pro podium, with Reimei Ito finishing fourth for SHOWA AUTO with BINGO RACING. The result gave De Haan both the overall victory and the fastest lap in a race where the wet track shaped the entire order.

Pro-Am

NGR's Hiro led the Pro-Am class throughout, also setting the fastest lap in the category with a 2:19.532.

Masaru Hamasaki finished second for VOING with VENTILER, while Chinese Taipei's Tiger Wu completed the class podium for BINGO RACING.

Eleven cars reached the finish across the three classes in a race that remained entirely wet from start to finish. De Haan's victory, fastest lap and overall lead highlighted the Pro-class result, while Tiger Wu's Pro-Am podium provided the only non-Japanese presence among the class podium finishers.
