Haruna Kuboyama ( Japanese: 久保山 晴菜; born 5 April 1996) [1] is a Japanese sprinter specializing in the 400 metres. She was the 2023 Japanese Champion in the 400 m, and won a bronze medal in the mixed 4 × 400 m relay at the 2023 Asian Championships.
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.

[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]
