Early Life and Tennis Journey
Naomi Osaka was born in Osaka, Japan, to a Japanese mother and a Haitian-American father.
She moved to the United States at age three and grew up first in New York, then Florida, alongside her older sister Mari, who also played professional tennis.
Osaka skipped the traditional junior circuit almost entirely and turned professional in September 2013, just before her 16th birthday.
Her breakthrough moment came at the 2014 Stanford Classic, where she qualified into the main draw and upset former US Open champion Samantha Stosur in her tour-level debut.
She spent the next several years climbing steadily, cracking the WTA top 50 in 2016 and earning WTA Newcomer of the Year honors after a run to the Pan Pacific Open final in Tokyo. That foundation set up her explosive rise in 2018.
Professional Tennis Career
Osaka’s career took off in 2018, when she won her first WTA 1000 title at Indian Wells and then claimed her maiden Grand Slam at the US Open, defeating her idol Serena Williams in the final.
The win made her the first Japanese player to capture a major singles title.
She backed it up in 2019 by winning the Australian Open, becoming the first Japanese and first Asian player to reach the world No. 1 ranking.
She added two more majors, the 2020 US Open and the 2021 Australian Open, becoming the first woman since Williams in 2015 to win consecutive Grand Slams.
A mental health withdrawal from the 2021 French Open and a quieter 2022 season, which included a runner-up finish at the Miami Open, slowed her momentum.
She then took a 15-month break in 2023 for the birth of her daughter, Shai, before returning to the tour in early 2024.
Her comeback gained real traction in 2025, with a final at the Canadian Open in Montreal, a semifinal run at the US Open, and a WTA 125 title in Saint Malo.
She carried that form into 2026, reaching the Bad Homburg final ahead of Wimbledon and climbing back to No. 14 in the world.
Coach
Osaka is currently coached by Tomasz Wiktorowski, a Polish coach who previously guided Iga Świątek to four Grand Slam titles and worked for years with Agnieszka Radwańska.
He joined Osaka on a trial basis in July 2025 at the Canadian Open in Montreal, shortly after her split from Patrick Mouratoglou, and the partnership was extended after she reached the final there.
Osaka has described his coaching style as direct and confidence-building, saying he has sharpened her in-match decision-making.
Before Wiktorowski, she worked with Wim Fissette across two separate stints and briefly with Mouratoglou in 2024 and 2025.
Naomi Osaka’s Net Worth Details
As of 2026, Naomi Osaka’s has an estimated net worth of $120 million.
She built this fortune primarily through endorsement income, with tennis prize money playing a smaller supporting role.
Career Prize Money
Osaka has earned more than $24.6 million in career prize money through June 2026. Her highest single-tournament payday came at the 2018 US Open, where the singles champion earned $3.8 million.
Her four Grand Slam titles account for a large share of that total, including an estimated $2.9 million from the 2019 Australian Open and $3 million from the 2020 US Open.
In the current 2026 season, she has earned $1,121,280 in prize money so far, per official WTA Tour statistics.
Annual Earnings and Endorsements Income
Endorsements make up the vast majority of Osaka’s income rather than on-court prize money.
Forbes tracked her total earnings at a record $60 million for the 12 months ending May 2021, then $59.2 million the following year, figures that made her the highest-paid female athlete in the world at the time.
More recently, Forbes estimated her earnings at roughly $0.9 million on-court and $12 million off-court for the year ending December 2024.
That split reflects how heavily her income now leans on endorsements even as her competitive results have fluctuated.

She also holds brand partnerships with Louis Vuitton as a Maison ambassador, TAG Heuer, Mastercard, and Panasonic, which named her an ambassador for its Green Impact sustainability campaign in 2021.
Beyond sponsorships, Osaka co-founded skincare brand KINLÒ in September 2021, production company Hana Kuma, and talent agency Evolve.
