Moyuka Uchijima (内島 萌夏, Uchijima Moyuka; born 11 August 2001) is a Japanese professional tennis player who has rapidly ascended the world rankings since turning professional. She achieved a career-high WTA singles ranking of world number 47 on 5 May 2025, along with a career-high doubles ranking of number 86 on 21 July 2025, and has accumulated more than US$2.3 million in prize money over her career. Uchijima has claimed two WTA 125 singles titles and one WTA Tour doubles championship, along with 13 singles and 11 doubles titles on the ITF Circuit, and currently stands as the Japanese number 2 player.
Born in Kuala Lumpur, Malaysia, to a Japanese father and Malaysian mother, Moyuka Uchijima developed her tennis game under a unique cross-cultural background that shaped her competitive approach. She represents Japan in international competition despite being born abroad, a detail that underscores her strong connection to her father’s homeland and the country she now calls home in international tennis. Her early exposure to tennis came through her family, and she developed her right-handed, two-handed backhand game that would become her signature stroke as she progressed through the junior and professional ranks.
She represented Japan in team competition, building a 6–3 record in Fed Cup play and gaining invaluable experience against seasoned international opposition. The climb from junior tournaments to the WTA Tour demanded years of consistent ITF Circuit performances, where Uchijima gradually built the game and ranking points needed to compete at the highest levels of the sport. Her breakthrough at the highest level of the women’s game required crossing into the top 100 of the WTA rankings and proving she belonged alongside the sport’s most established names.
Moyuka Uchijima’s early professional years were defined by deep runs in ITF Circuit events across Asia and Europe, where she accumulated 13 singles and 11 doubles titles while steadily climbing the rankings. She built a professional record of 276 wins against 196 losses in singles and 121 wins against 100 losses in doubles, using that ITF Circuit success to earn qualifying opportunities at higher-level WTA Tour events. Those results positioned her to qualify for her first Grand Slam main draw at the 2023 Australian Open, where she made her major debut and played alongside the world’s best players for the first time.
In 2024, Uchijima won three consecutive ITF Circuit titles in May, a run that lifted her to a career-high ranking of world number 80 and made her the Japanese number 1 female singles player for the first time. She qualified for the 2024 French Open, making her debut at the tournament, and defeated fellow qualifier Irene Burillo Escorihuela in the first round before falling to second seed Aryna Sabalenka in straight sets. She also qualified for the 2024 Canadian Open and recorded her first WTA 1000 win over Viktoriya Tomova, then made her debut at the 2024 US Open and defeated Tamara Korpatsch in the first round, reaching the second round at multiple major tournaments in the same season.
In September 2024 at the WTA 250 Thailand Open 2, Uchijima reached her first WTA Tour doubles final partnering with Eudice Chong before losing to top seeds Anna Danilina and Irina Khromacheva. Partnering Guo Hanyu, she won her maiden WTA Tour doubles title at the 2024 Jiangxi Open, defeating Katarzyna Piter and Fanny Stollár in the final to claim her first trophy on the main WTA Tour. That doubles breakthrough marked a significant milestone in her career and demonstrated her ability to compete across both disciplines of the sport.
In 2025, Uchijima reached her career-high WTA singles ranking of world number 47 on 5 May 2025, climbing into the top 50 of the sport for the first time in her career. Ranked world number 63, she defeated Magda Linette to reach the second round at the Australian Open, where she pushed 14th seed Mirra Andreeva to a deciding set tiebreak. At the Madrid Open in April, she reached her first WTA 1000 quarterfinal with wins over wildcard entrant Robin Montgomery, 26th seed Ons Jabeur, world number 3 Jessica Pegula for her first victory over a top-25 ranked player, and 21st seed Ekaterina Alexandrova in the fourth round before losing to 17th seed Elina Svitolina in the last eight.
Uchijima reached the second round at the 2024 and 2025 US Open and the 2025 and 2026 Australian Open, while making her Wimbledon debut in 2024 and advancing to the second round at the 2025 French Open. She also competed in doubles at the 2024 Summer Olympics and reached the second round in women’s doubles at the 2025 French Open. In February at the Dubai Tennis Championships, she qualified for the main draw and recorded her first win against a top-30 ranked opponent by defeating world number 26 Jelena Ostapenko before losing in the second round to sixth seed Elena Rybakina.
Uchijima’s game is built around her right-handed baseline play with a reliable two-handed backhand, a shot that has become her most dangerous weapon in competitive matches. Her height advantage at 174 centimeters allows her to generate solid pace and depth on both wings, giving her the ability to compete effectively on a range of surfaces and conditions. She has shown particular strength in extended baseline rallies and has demonstrated an improving serve that has become more of a weapon as she has gained experience at the highest levels of the sport.
Her victory over world number 3 Jessica Pegula at the 2025 Madrid Open stands as the defining result of her career to date, a statement win that announced her arrival as a genuine contender on the WTA Tour. She also saved seven match points to defeat Olga Danilović at the 2024 US Open, showcasing her resilience and fighting spirit under extreme pressure. Winning her first WTA Tour doubles title at the 2024 Jiangxi Open represented another milestone achievement that highlighted her versatility and commitment to developing her game across both singles and doubles competition.
