Early Life and Background
Naomi Osaka was born to Leonard François, a Haitian-American from Jacmel, Haiti and Tamaki Osaka from Nemuro, Hokkaido, Japan on October 16, 1997 in Chūō-ku, Osaka, Japan. She has an older sister, Mari, who also was a professional tennis player. Osaka moved from Japan to the United States at three or four years old and she has lived and trained there ever since. “She grew up in America, but her parents made the choice early on that she and her sister would represent Japan,” said the decision was never a question of finances and that Naomi had always felt Japanese.

A Breakout Debut
Osaka became famous at 16 when she defeated former US Open champion Samantha Stosur in her WTA Tour debut at the 2014 Stanford Classic. Her rise was gradual but unmistakable. In 2017, she reached her second Top 100 season, finishing at No. 68 as the Japanese No. 1, and scored her first Top 5 win, beating Venus Williams at the Hong Kong tournament that year.
Grand Slam Greatness
Osaka’s meteoric rise to the very top of the sport was historic. In 2018, she won her first two career titles at the WTA Premier Mandatory level in Indian Wells, then won her first Grand Slam title at the US Open, defeating six-time champion Serena Williams in the final to become the first Japanese player to win a Grand Slam title. She followed that up by going from strength to strength to become the first Japanese player to reach the World No. 1 ranking after her 2019 Australian Open triumph. She tightened her grip on the majors by winning a third title at the US Open in 2020 and a fourth at the Australian Open in 2021, becoming the first woman since Monica Seles in the early 1990s to win each of her first four Grand Slam finals.

Playing Style
On the court, Osaka is known for an aggressive style of play built around a powerful serve that can reach 201 kilometres per hour (125 mph). Her flat, penetrating groundstrokes and ability to dictate points from the baseline make her one of the most dangerous hard-court players in the world, especially at the Australian Open and US Open, where she has won all four of her major titles.
Mental Health and Maternity Leave
Osaka has been as much a presence off the court as on it. The 2021 French Open withdrew to protect her mental health, taking a long break from the sport. She competed at the Tokyo tournament in September 2022 and then took a 15-month break before having her daughter, Shai, in early July 2023. Her candour about mental health and the pressures of professional sport made her a powerful voice on those issues around the world.
Back to the drawing board
Osaka returned to play in 2024 after her maternity leave and made the quarterfinals in Doha and ‘s-Hertogenbosch. Her comeback gathered real steam in 2025. In the spring, she won her first WTA title since the 2021 Australian Open at the WTA 125 event in Saint Malo, then reached the final of the Canadian Open in August, beating Jelena Ostapenko and Elina Svitolina before being beaten by Canadian prodigy Victoria Mboko. She also made the semi-finals at the US Open, returning to the Top 20 for the first time since January 2022.
Legacy & 2026
In 2021, Osaka was awarded the Laureus World Sportswoman of the Year award and became the first tennis player to light the Olympic cauldron at the opening ceremony of the 2020 Tokyo Olympics. She is currently ranked world No. 16 in 2026 with a 7–4 win–loss record for the year, and is one of only four active women on tour with four or more Grand Slam titles. Osaka’s elite talent, renewed focus and one of the most powerful games in women’s tennis make her one of the sport’s most compelling figures, both as a champion and as a personality who has helped reshape the conversation around athlete wellbeing.
