The first half of the 2023 campaign was disappointing for the ARTA team, with only one third-place finish for each of their cars. However, at Suzuka, Nirei Fukuzumi and Hiroki Otsu secured victory from pole position, giving Honda their first win of the season. Otsu’s pit stop before the first full-course yellow gave him a significant advantage over his competitors. Despite a fuel shortage, the team managed to save enough to finish the race. Ronnie Quintarelli, who was closing in on Otsu, had to manage front tire wear and gearbox overheating. Quintarelli handed over to Tsugio Matsuda, but they were later disqualified due to an issue with their skid block.
