Early career Furusato was born in Kanoya, Japan. He performed well in national junior categories and was selected to compete in the
2020 Asia Talent Cup season. He finished second in his debut race, but the championship was cancelled after just one round in
Qatar due to the
COVID-19 pandemic. The cup returned for the
2021 season in which Furusato won every round on the calendar, and consequently the championship. A feat that, as of now, no other rider has been able to replicate. That same year, Furusato was given a mid-season opportunity to replace an injured rider in the
2021 Red Bull MotoGP Rookies Cup. He went on to win his debut race in
Mugello, his first time riding a KTM bike and competing on that track. He finished the season in 11th place. These results granted him a seat in the
2022 Moto3 World Championship with
HRC's Honda Team Asia, where he was partnered with
Mario Aji.
Moto3 World Championship Honda Team Asia (2022–2025) Furusato had a difficult start to the World Championship after suffering a foot injury during pre-season testing in
Jerez, which made him sit out the first two rounds in
Qatar and
Indonesia. He struggled in his debut season, scoring points only in his home race at
Motegi, where he finished in 14th place. In
2023, Furusato progressed positively, consistently scoring points in the second half of the season, with several top-10 finishes, including a maiden podium for his standout second-place finish in
Thailand. He ended the season in 16th place in the championship standings. Furusato's
2024 Moto3 season began with a podium finish in Qatar, narrowly trailing
David Alonso and
Daniel Holgado in a tight battle to the line. Furusato clinched two more podiums during the season, both second-place finishes in
Germany and
Malaysia, respectively. He finished tenth in the final standings and was confirmed to remain in Moto3 for a fourth season, alongside Tatchakorn Buasri.
Moto2 World Championship Honda Team Asia (2026) In October 2025, Honda announced Furusato will be stepping up to the
2026 Moto2 World Championship, alongside
Mario Aji, after four full-seasons in the lightweight class. ==Career statistics==
