Professional career
Yamanaka made her professional boxing debut on 13 December 2020, scoring a unanimous decision win over Arika Shimono at Edion Arena in Osaka.[3]
She won the vacant WBO Asia Pacific 102-pound belt by stopping Honoka Kano in the fifth round of their bout at Tokyo's Korakuen Hall on 1 September 2022.[4]
On 12 January 2024, Yamanaka captured the IBF female atomweight title with a unanimous decision success against defending champion Mika Iwakawa also at Korakuen Hall.[5][6][7]
Yamanaka was scheduled to make the first defense of her title against former WBC female atomweight champion Fabiana Bytyqi at Olympiastuetzpunkt in Heidelberg, Germany, on 23 November 2024.[8] The bout was cancelled after Bytyqi collapsed due to dehydration on the day of the weigh-in.[9]
She faced WBC, WBA and WBO female atomweight title holder Tina Rupprecht in a contest to crown an undisputed champion for the division at the MBS Arena in Potsdam, Germany, on 5 April 2025.[10] Yamanaka lost by majority decision with two of the ringside judges scoring the contest 99–91 and 96–95 respectively for her opponent, while the third had it a 95–95 draw.[11][12][13]
Yamanaka became a two-time IBF female atomweight champion when she defeated the previously unbeaten Nao Ugawa via split decision for the vacant title at Korakuen Hall in Tokyo on 7 April 2026. Two of the judges awarded her the fight 97–93 and 96–94 respectively, overruling the third who gave it 96–94 for her opponent.[14][15][16]
