Seita Nonaka (野中 誠太, Nonaka Seita; born 25 October 2000) is a Japanese racing driver set to compete in Super GT for Saitama Green Brave, and in Super Formula for team KCMG. He previously raced in Super Formula Lights, and was most notably the 2021 Japanese F4 champion. Nonaka is part of the TGR Driver Challenge program.

Career

F4 Japan

Nonaka started racing in 2019, competing in F4 Japanese Championship with TOM'S Spirit and managed to claim eighth in his rookie season. He stayed in the same series, but joined TGR-DC Racing School.[1] In that season, he claimed third place in the final standings. Nonaka once again continued to compete in the same series for the third season for 2021 with the same team from 2020. That season, he clinched the title from Rin Arakawa & Iori Kimura in the last round at Fuji Speedway.[2]

Super Formula Lights

In the same year of 2021, Nonaka competed in Super Formula Lights, where he replaced Kazuto Kotaka who originally should compete in the series, but have to race in Super Formula with KCMG covered Kamui Kobayashi, who was not able to compete in Japan due to travel restrictions.[3] Nonaka competed all but one of the six rounds held that year.

For the next two seasons, Nonaka continued racing Super Formula Lights with the same team, claiming a win and nine podiums. He finished the year in fourth place in 2022, and finished seventh with four podiums in 2023.[4] He continued the series for the third season with TOM'S again.[5] Nonaka stayed for his fourth season in 2024, once again with TOM'S.[6]

Super Formula Championship

For 2026, Nonaka was due to stay in Super Formula Lights for yet another season, however, he was promoted to the KCMG team in the Super Formula Championship, following the withdrawal of Kalle Rovanperä for the season due to a medical issue.[7] Nonaka will drive car No. 9, and his team-mate will be Kenta Yamashita.

Super GT

Nonaka makes his Super GT GT300 debut with Team Tsuchiya with Takashi Matsui partnering him.[8] He continued racing with the same team, but with new partner Togo Suganami.[9] Unfortunately, he only managed to race for four rounds, as the last round he did at Fuji Speedway, his car caught on fire and burned badly and Nonaka safely out from the incident.[10] Nonaka joined Saitama Toyopet GreenBrave as a third driver. He won the race but did not take a single lap thus was not classified for points.[11] In 2024, Nonaka was promoted to full-time seat with 2023 GT300 champion team Saitama Green Brave, as he replaced Kohta Kawaai.[12]

Other series

In 2023, Nonaka raced in GT World Challenge Asia with Toyota Gazoo Racing Indonesia. He claimed 5 wins from 6 races.[13] Nonaka stayed with the team for SRO Japan Cup for two seasons in 2024 and 2025.[14][15]
