Kakunoshin Ohta

is a Japanese racing driver for Honda Motor Company who currently competes in Super GT for Astemo Real Racing and in Super Formula for docomo Team Dandelion Racing and the IMSA SportsCar Championship for Acura Meyer Shank Racing and Era Motorsport in the GTP and LMP2 class.

Career Early career Ohta made his single-seater racing debut in 2018, racing at a single round of the F4 Japanese Championship with . The following season, he made his full-time debut in the 2019 championship with backing from the Honda Formula Dream Project, claiming 2 wins but finishing 6th in the standings. That year, Ohta also made a guest appearance in the French F4 championship alongside Honda stablemate Ren Satō, where he finished in the top ten in the three races he competed in and secured one podium. He would also make an appearance in Japan Formula 4 at the end of the year, winning the "All-Japan Deciding Race" over the likes of Satō, Atsushi Miyake, and Riki Ōkusa.

In 2020, Ohta returned to the F4 Japanese Championship, albeit having lost his manufacturer backing. Belying his past record, he impressed immediately, claiming four wins and twelve podiums to finish second in the championship, behind only the returning Kazuto Kotaka.

Super GT GT300 Ohta began his Super GT career in GT300 with Team UpGarage, paired with veteran driver Takashi Kobayashi. After a promising season, Ohta moved to Real Racing as he replaced Nobuharu Matsushita, and raced along with Koudai Tsukakoshi.

Super Formula 2023

Following his performance in Super Formula Lights, Ohta was promoted to a top-level drive in the Super Formula Championship for 2023, racing for docomo Dandelion Racing alongside Tadasuke Makino and in place of Hiroki Ōtsu.

2024 Ohta returned to Dandelion in 2024. Ohta finished fifth at Autopolis preceded a non-score at SUGO, as he went off at the final corner during a restart in wet conditions. He failed to start the next race at Fuji before experiencing a strong run at Motegi, qualifying second and progressing to the lead thanks to an undercut strategy. However, he was chased down by teammate Makino in the closing stages and lost the victory on the penultimate lap, as a throttle issue caused him to spin out of the race. Ohta had another strong qualifying session in Fuji, as he started from second, but dropped to ninth by the flag due to degrading tyres in the final laps. He finished the second race of the weekend in fourth. At the final event in Suzuka, Ohta qualified on pole for race 1 before cruising to a dominant victory. Starting from second the following day, he took the lead at turn one and later defended against Sho Tsuboi right after the pit stop phase to clinch his second successive victory. He ended the year fourth in the standings.

2025 Ohta continued to stay with Dandelion Racing for 2025 season.

Endurance racing Ohta was given a chance to test the Acura ARX-06 in the IMSA Sanctioned Test at Daytona International Speedway in November 2024.

On 11 December 2024, it was announced that Ohta would be driving three races during the 2025 IMSA SportsCar Championship in the 93 Acura Meyer Shank Racing Acura ARX-06, alongside Renger van Der Zande and Nick Yelloly, for the Rolex 24 Hours at Daytona, Six Hours of the Glen at Watkins Glen and the Battle of the Bricks at Indianapolis Motor Speedway, and Alex Palou for the Rolex 24 exclusively.
