Beginning as a short sprinter as early as 2014, Kuboyama won the 2018 Japanese University Championships in the 100 metres, running 11.86 into a -2.1 m/s headwind.[1] At her first Japanese Athletics Championships in 2019, she contested the 100 m and 200 m but did not advance to the finals. She also failed to advance to the 100 m finals at the 2020 Japanese Athletics Championships.[1]
Kuboyama switched events to the 400 metres in 2021, debuting at 54.90 and eventually finishing 4th at the 2021 Japanese Athletics Championships in 53.72.[1] After a 3rd-place 400 m finish at the 2022 Japanese Athletics Championships, Kuboyama was named to the Japanese mixed 4 × 400 m team at the 2022 World Championships as an alternate, but she did not get to compete as Japan did not qualify for the finals.[4][1]
Kuboyama achieved her best national results in 2023, winning the 400 m at the national championships and placing 3rd in the 200 m. This earned her selection to Japan's 4 × 400 m, individual 400 m, and mixed 4 × 400 m teams at the 2023 Asian Athletics Championships. After finishing 4th in the individual 400 m, she won a bronze medal running second leg of the mixed relay final, setting a Japanese record of 3:15.71 in the process. The following day she also placed 4th leading off the women's 4 × 400 m.[1] [5]
In April 2024, it was revealed that 2023 Asian Championships 400 m silver medallist Fairda Soliyeva of Uzbekistan failed a test for meldonium, disqualifying her and promoting Kuboyama to the bronze medal.[6]
Kuboyama began her 2024 season finishing 4th at the Asian Indoor Athletics Championships in the 400 m. She finished 8th at the 2024 Diamond League Shanghai outdoors.[1]
Kuboyama is from Saga, Japan where she attended Saga Kita High School [ja] and Fukuoka University.[2] She competes representing Imamura Hospital [d].[3]
