Miyu Kato Bio
Miyu Kato (加藤 未唯, Katō Miyu; born 21 November 1994) is a Japanese professional tennis player who specializes in doubles. Based in her hometown of Kyoto, Japan, she turned professional in 2013 and built her career on the ITF Circuit before moving up to the WTA Tour. On 1 January 2024, she reached her career-high doubles ranking of world No. 26.
Throughout her career, Miyu Kato has become one of Japan’s most reliable doubles competitors. She has collected five doubles titles on the WTA Tour, added two WTA 125 doubles titles, and also captured four singles and 13 doubles titles at the ITF level. She has represented Japan’s Billie Jean King Cup team with a strong 6–1 win–loss record.
Early Life and Background
Miyu Kato was born on 21 November 1994 in Kyoto, Japan, where she still resides. She grew up in a sports-oriented household and has one brother named Yuki. Kyoto, known for its deep cultural traditions and strong local tennis clubs, gave her an early environment in which to develop her game.
Kato began playing tennis at the age of eight, a relatively late start compared with many touring professionals. She has spoken about her admiration for Justine Henin and Roger Federer while growing up, citing them as the players who shaped her competitive mindset. Her favorite surface to play on is hardcourt, although she has named Wimbledon as her favorite tournament.
Standing 1.56 m (5 ft 1 in) tall, Kato plays right-handed with a two-handed backhand, an unusual combination that has given her a compact and steady style from the baseline and at the net. As a junior, she reached the girls’ doubles final at a Grand Slam event, an early sign of her doubles potential.
Path to Professional Tennis
Kato’s road to the professional tour began on the ITF Circuit, where she collected four singles and 13 doubles titles while climbing the world rankings. Her singles game improved steadily enough to push her to a career-high singles ranking of No. 122 on 15 January 2018, even though she never lifted a WTA singles trophy.
Turning professional in 2013, she balanced singles and doubles for several seasons before making doubles her clear priority. She made her Grand Slam main-draw singles debut at the 2017 French Open and has appeared in qualifying rounds at the Australian Open, Wimbledon, and the US Open. The shift in focus allowed her to specialize in the format where she could make the deepest runs.
Working with coach Adam Lownsbrough, Kato refined her net play, return positioning, and tactical awareness. Her results on the ITF Circuit translated into WTA Tour main-draw appearances, where she began posting early-round upsets and reaching her first WTA doubles finals.
Miyu Kato Career
Early Career (2013–2016)
During her first years on tour, Miyu Kato competed mainly on the ITF Circuit in both singles and doubles, building her ranking through consistent week-to-week results. She reached her first WTA Tour doubles final during this period, setting the stage for bigger breakthroughs on the main tour.
By 2016, Kato had cracked the WTA doubles top 100 and was regularly qualifying for Grand Slam doubles draws. Her early-round showings against top-seeded pairs gave her the experience needed to compete in the biggest events on the calendar.
WTA Tour Breakthrough (2017–2022)
Kato’s first major breakthrough came at the 2017 Australian Open, where she reached the women’s doubles semifinal. That run announced her as a rising doubles specialist and helped push her ranking close to the WTA top 30 within a few seasons.
Over the following years, she captured her first WTA doubles titles and added multiple runner-up finishes. Her career record at WTA Tour finals reached 17 doubles appearances, with five titles and 12 runner-up finishes, a sign of her consistency at the highest level. She also added three WTA 125 doubles titles and one runner-up finish at that level.
Major Titles and Top-Level Finals (2023–2025)
The 2023 season was the most dramatic of Miyu Kato’s career. At the 2023 French Open, she and partner Aldila Sutjiadi were defaulted from the women’s doubles after Kato accidentally struck a ball girl with a ball, forfeiting her points and prize money. She announced she would appeal the decision and received public support from fellow players and the Professional Tennis Players Association.
That same Roland Garros run ended with a career highlight, as Kato won the 2023 French Open mixed doubles title with German partner Tim Pütz, her first Grand Slam trophy. The week she was selected for the 2023 WTA Elite Trophy in Zhuhai alongside Sutjiadi, she climbed to a new career-high doubles ranking of No. 27 on 23 October 2023.
In 2024, Kato and Sutjiadi captured the doubles title at the 2024 Thailand Open, defeating Guo Hanyu and Jiang Xinyu in the final. She also reached the quarterfinals of the 2024 French Open women’s doubles and the third round of the US Open doubles, while reaching a new career-high ranking of No. 26 on 1 January 2024.
In 2025, Kato reached the doubles final of the WTA 1000 Miami Open with new partner Cristina Bucșa, knocking out top seeds and world No. 1 and No. 2 pair Kateřina Siniaková and Taylor Townsend before falling to Mirra Andreeva and Diana Shnaider. Later that season, teaming with Fanny Stollár, she reached the doubles final at the WTA 1000 China Open, losing to second seeds Sara Errani and Jasmine Paolini in a championship tiebreak.
