Naomi Osaka

Osaka's career is decorated with major achievements. She has been ranked No. 1 by the Women's Tennis Association and is the first Asian player to hold the top ranking in singles. She is a four-time Grand Slam singles champion and the reigning champion at both the US Open and the Australian Open. Her seven titles on the WTA Tour include two at the Premier Mandatory level. She won her first two Grand Slam titles back-to-back at the 2018 US Open and the 2019 Australian Open, becoming the first player to achieve this feat since Jennifer Capriati in 2001. She also became the first woman to win successive Grand Slam singles titles since Serena Williams in 2015.

Osaka came to prominence at age 16 when she defeated former US Open champion Samantha Stosur in her WTA Tour debut at the 2014 Stanford Classic. Two years later, she reached her first WTA final at the 2016 Pan Pacific Open in Japan, entering the top 50 of the WTA rankings. In 2018, she won her first WTA title at the Indian Wells Open and later defeated 23-time Grand Slam champion Serena Williams in the US Open final, becoming the first Japanese player to win a Grand Slam singles title. Since 2018, she has won a Grand Slam singles title in four consecutive years.

Osaka is also one of the world's most marketable athletes, ranked eighth among all athletes in endorsement income in 2020. She was the highest-earning female athlete of all time by annual income that year. Her activism, including support for the Black Lives Matter movement, earned her recognition as one of the 2020 Sports Illustrated Sportspersons of the Year. She has been included on Time's list of the 100 most influential people in 2019 and 2020, and she was the 2021 Laureus World Sportswoman of the Year. At the 2020 Tokyo Olympics, she became the first tennis player to light the Olympic cauldron. On the court, Osaka plays with an aggressive style, featuring a powerful serve that can reach 201 kilometers per hour (125 mph).
