Rio Noguchi built a hard-court career from Tokyo to two Bangkok trophies
Rio Noguchi qualified for his ATP Tour debut at the 2022 Japan Open and immediately earned a first tour-level win over Ramkumar Ramanathan. That week followed back-to-back ITF M25 titles in Sapporo. He later broke through at Challenger level on the hard courts of Nonthaburi, beating Cui Jie for a title in 2025 and Marek Gengel 6-3, 6-4 for another in January 2026. The five-foot-six player from Fukuoka reached a career-high No. 196 in singles and lists hard court as his preferred surface.
