Noda tested single-seater race cars on Japanese circuits from the age of 9.[2] She made her official competition car debut in the 2019 Lucas Oil Winter Race Series, where she finished 14th overall.
F4 Danish Championship
Noda made her debut in the Formula 4 category in 2020, racing in the F4 Danish Championship with her family team, Noda Racing. She won her first ever race in the series, and finished 6th in the standings.
She continued in the championship in 2021, after a last minute switch from the F4 United States Championship.[3] She finished 7th in the standings this year.
She was fastest in the practice session in Round 1 at Road Atlanta, however she then withdrew prior to qualifying.[5] She did not appear at any more rounds.
W Series
Noda appeared at the second pre-season test on 2–4 March 2022 at Barcelona, the only driver to do so who was not an automatic qualifier or who had attended the first test in Arizona, one month prior. The full W Series grid was announced on 22 March 2022, with Noda included.[1] She would go on to score two points throughout the season, finishing fourteenth in the championship.
Noda would compete in the Euroformula Open Championship for the eponymous Noda Racing team in 2023. She currently lies fifth in the standings with one win, albeit under the beneficiary under a controversial technical regulation stating that female drivers in the championship could run at a minimum weight 26 kg lower than male counterparts.[6] This regulation was abolished before the fifth round of the season at the Red Bull Ring, mandating her car to be run with the same minimum weight as those of her male competitors.[7] In response to this, Hideki Noda announced that they had retired Juju and the Noda Racing entry from the series.
Noda stepped up to Super Formula in 2024, partnering Nobuharu Matsushita at TGM Grand Prix. Noda became the first Japanese woman to race in Super Formula, Formula Nippon or any of its predecessors. Despite a best finish of twelfth in the attritional penultimate race at Suzuka, Noda struggled with a lack of professional-level motorsport experience – never qualifying higher than 19th in a 21-car field, and lapping on average 1.7 seconds slower than the leaders across the season.[8]
