Kyojo Cup debut and early success (2019–2021)

After winning the Kart race and finishing third overall in the TGR-sponsored Dual Attack event, Onaga was given the TGR Woman Award and a drive in both the 2019 Toyota Gazoo Racing GR86/BRZ Cup and the Netz Cup Vitz Race.

On her debut, Onaga started second and overtook Hinako Muramatsu in the closing stages of the race to take her maiden win in the series by less than three tenths. Despite finishing runner-up in the final two races of the season, Onaga lost out on the title by one point after Muramatsu won the final race and the title.
In 2020, Onaga returned to Kyojo Cup. In the opening race of the season, she passed Ai Miura on the opening lap and won the red-flagged race by over seven seconds. Despite ending the season with a win in the finale, Onaga lost out on the title to Miura by thirteen points.
