Hiyu Yamakoshi (山越陽悠, Yamakoshi Hiyū, born 13 October 2006) is a Japanese racing driver who is set to compete in the 2025 Formula Regional European Championship with Van Amersfoort Racing. He previously competed in the 2024 Italian F4 Championship with the same team, finishing third overall in the standings.[1]
Career
[edit]Karting
[edit]Yamakoshi entered in two notable karting championships, the 2020 IAME Japan Series in the X30 Junior class where he finished in 3rd, and the 2022 CIK-FIA European Championship in the OK category for IPK Official Racing Team, where he finished in 30th.
Formula 4
[edit]Formula 4 UAE Championship
[edit]2023
[edit]He made his single-seater debut in the 2023 Formula 4 UAE Championship for Pinnacle VAR, he drove in two of the five rounds in the championship at the Kuwait Motor Town, under the Filipino license. After a pointless first round, Yamakoshi acclimated 8 points in his second round, and finished 22nd in the championship.[2]
2024
[edit]Yamakoshi planned to drive in the final two rounds of the 2024 Formula 4 UAE Championship for Pinnacle Motorsport but pulled out of the final round due to a injury, he finished the championship in 32nd position.[3]
French F4 Championship
[edit]Yamakoshi would compete in the 2023 French F4 Championship for his full-time campaign, where he scored a chain of points in his first two rounds, including a maiden podium at last race of the second round at Magny-Cours and another podium at the first race of the third round at Pau, the next race was a retirement and the final race of the round was points scoring with a maiden fastest lap.[4]
The fourth round at the Spa-Francorchamps was also consistent points-wise. He got second fastest lap of his campaign in the second race, and then in the third race he achieved the best result of his campaign so far, a 2nd place. The fifth round at Misano was forgettable, as he failed to enter the top ten in all three races, with a 17th place, 12th place and a retirement in the final race.
The penultimate round of the championship at Lédenon started poorly with a retirement in the first race, but Yamakoshi would claim another podium in a second race, and would end the round with a fourth place. In the championship finale at Le Castellet he retired from the first two races but ended his maiden Formula 4 full-time season with a third place finish. Yamakoshi finished the championship in 5th place overall with 146 points.
F4 Spanish Championship
[edit]2023
[edit]Alongside his French F4 Championship campaign, he would add a second Formula 4 campaign to his schedule, driving for Tecnicar - Fórmula de Campeones in the 2023 F4 Spanish Championship. Yamakoshi scored points in his debut round at the Aragón, with a ninth place in his first race. His second round at Navarro saw him retire from two races and come 14th in the only race of the round he finished.[5]
The rest of Yamakoshi's partial campaign saw him score various points finishes in inferior machinery, as he finished the season in 14th with 19 points.
2024
[edit]He partnered up with Monlau Motorsport for the fourth round of the 2024 F4 Spanish Championship at Aragón as a guest driver. Coming 8th in the first race, retiring in the second race and coming 14th in the third race. Since he was a guest driver he was eligible to score points, but was also the highest finishing guest driver by the end of the season.
Italian F4 Championship
[edit]For 2024, Yamakoshi's main campaign lied in the Italian F4 Championship with Van Amersfoort Racing, where he scored points in all three races in his debut at Misano, with a 6th place and two 4th places.[6]
At Imola Circuit, he claimed pole positions in all three races, he got his first race win in the series at race one, after original race winner Freddie Slater was disqualified due to a technical infringement. Yamakoshi would also win the second race, but came 27th in the third race.
Imola would be the highest point in the series for him, as Slater would dominate the championship, leaving Yamakoshi to settle for podiums instead of fighting for wins. At the third round in Vallelunga Circuit, he came third in all three races, and enjoyed consistent success throughout his campaign, but would become less consistent in the latter half of the season, and scored no points at the final round at Monza, getting narrowly beaten by teammate Jack Beeton for series runner-up by two points. Yamakoshi finished the championship in 3rd place with two wins, three pole positions, three fastest laps, seven podiums and 220 points.
Euro 4 Championship
[edit]Yamakoshi also contested the 2024 Euro 4 Championship with Van Amersfoort Racing, where in the first race at Misano, he got a second place and then a win in the second race. He also picked up a second win in the second round at the Red Bull Ring, and would finish the championship in 4th overall, with 89 points.
Formula Regional
[edit]In 2025, Yamakoshi moved up to the Formula Regional European Championship, continuing with Van Amersfoort Racing.[7]
