Career
Karting
Yamakoshi's karting career includes notable appearances such as the 2020 IAME Japan Series (X30 Junior category), where he finished third, and the 2022 CIK-FIA Karting European Championship in the OK class racing for IPK Official Racing Team, concluding the event in 30th position.
Formula 4
Formula 4 UAE Championship
2023
He made his single-seater debut during the 2023 Formula 4 UAE Championship, competing with both Pinnacle and Van Amersfoort Racing. Participating in two out of five rounds at Kuwait Motor Town, he raced under a Filipino license. Although he did not score points in his initial round, he accumulated 8 points in the subsequent round, finishing 22nd in the championship.
2024
Yamakoshi intended to take part in the final two rounds of the 2024 Formula 4 UAE Championship with Pinnacle Motorsport, but an injury forced him to withdraw from the last round, resulting in a 32nd place overall finish.
French F4 Championship
In his full-season effort during the 2023 French F4 Championship, Yamakoshi consistently earned points early on, including podium finishes at both Magny-Cours and the Pau event. Following a retirement, he bounced back by scoring points and registering his first fastest lap.
At Spa-Francorchamps, he maintained consistent points scoring and achieved his best result so far with a second-place finish in the third race. The fifth round at Misano proved challenging, with finishes outside the top ten and one retirement.
During the penultimate round at Lédenon, after recovering from an initial retirement, Yamakoshi secured a podium and a fourth-place finish. In the final round at Le Castellet, despite two retirements, he managed to claim a third-place finish. He wrapped up his inaugural full Formula 4 season fifth overall with a total of 146 points.
F4 Spanish Championship
2023
Alongside his French F4 campaign, Yamakoshi participated partially in the 2023 F4 Spanish Championship driving for Tecnicar - Fórmula de Campeones. He earned points on his debut at Aragón by finishing ninth but encountered difficulties at Navarro, where he retired twice and finished fourteenth once.
Despite competing with less competitive equipment, he secured multiple points finishes and ended the season ranked 14th with 19 points.
2024
For the fourth round of the 2024 F4 Spanish Championship at Aragón, Yamakoshi joined Monlau Motorsport as a guest driver. He finished eighth in race one, retired from race two, and placed fourteenth in race three. Although not eligible to score points as a guest entrant, he was the highest finishing guest driver that season.
Italian F4 Championship
In 2024, Yamakoshi concentrated his efforts on the Italian F4 Championship driving for Van Amersfoort Racing. He scored points in each of his three races during his debut weekend at Misano, securing a 6th place finish and two 4th places.
At Imola Circuit, he achieved pole position in all three races and earned his maiden victory in race one following the disqualification of initial winner Freddie Slater due to a technical violation. Yamakoshi also triumphed in race two but dropped to 27th in race three. Despite these strong showings, Slater dominated the championship, relegating Yamakoshi to podium finishes rather than multiple wins. During the third round at Vallelunga Circuit, he consistently placed third across all three races, maintaining steady results throughout the season. However, his performance waned toward the end, failing to score points at the final round at Monza and narrowly missing out on second place in the standings by just two points to teammate Jack Beeton. Ultimately, Yamakoshi concluded the championship in 3rd place overall, boasting two victories, three pole positions, three fastest laps, seven podiums, and a total of 220 points.
Euro 4 Championship
Yamakoshi also took part in the 2024 Euro 4 Championship with Van Amersfoort Racing. He secured a second-place finish and a win at Misano, followed by another victory during round two at the Red Bull Ring. He wrapped up the season ranked 4th overall with 89 points.
