Japan’s Naomi Osaka, a four-times Grand Slam tennis champion who has helped raise awareness of mental health issues in sport, is the world’s highest-paid female athlete, according to a list published by business magazine Forbes on Thursday.
Osaka raked in $57.3 million in prize money and endorsements over the last year, nearly all of which came from an endorsement portfolio that has added more than 10 brand partners over the last year and a half.
