Hiroki Ohtsu is an established professional competing at 6,422 Racer Rating, a ranking that places him among the stronger full-time drivers in his series but not among the elite. His entire recorded career spans nine seasons in Super GT from 2018 to 2026, where he has accumulated one win and six podiums across 60 starts for Team HRC ARTA Mugen, finishing on average in 13th place. This mid-field positioning reflects consistent engagement with a national championship field but limited success relative to his peers.[1]
Ohtsu operates in an exceptionally strong field. His most frequent rivals are multiple Super GT champions and FIA Platinum-graded drivers; Sho Tsuboi, a three-time Super GT champion, has finished ahead of him in 43 of 59 shared races, while Tadasuke Makino, the 2020 and 2025 Super GT champion, and Naoki Yamamoto, a two-time champion, have also dominated their head-to-head records. Ohtsu has nevertheless beaten all three of these higher-rated drivers on multiple occasions. He holds a notably strong record against Hiroki Yoshimoto, a Gold-graded professional, finishing ahead of him in 51 of 59 races, demonstrating clear superiority at that tier.
Ohtsu remains active as of 2026, having raced in two rounds of that season's Super GT without recording a podium. His career represents that of a dependable mid-field professional in one of Japan's premier racing categories, capable of occasional race wins and podium finishes against national-level competition and intermittently competitive with the championship-winning drivers who share his grid.
