Naomi Osaka is a Japanese tennis player ranked WTA World #15 and a four-time Grand Slam champion. The 28-year-old has won the US Open (2018, 2020) and the Australian Open (2019, 2021), making her one of the most decorated hard-court players in the history of women’s tennis. Beyond her on-court achievements, Osaka has become one of the most recognized athletes in the world and a powerful voice on issues of mental health and racial identity.
Osaka’s game at its peak is built on one of the most powerful serves in women’s tennis and a forehand that can overpower any opponent. Her serve regularly exceeds 120 mph, and her flat groundstrokes generate pace that few players can handle. When she is locked in, her combination of power, timing, and shot placement is virtually unplayable on hard courts. Her movement and clay-court game have been areas of development throughout her career, but on her preferred surface, she has demonstrated a level of tennis that matches anyone in the sport’s history.
Osaka’s career has been defined by both brilliance and courage. After winning four Grand Slams in her early twenties, she stepped away from the sport to prioritize her mental health, sparking a global conversation about athlete wellbeing. Her return to competitive tennis, including navigating motherhood and a comeback through the rankings, has added new chapters to an already remarkable story. Her willingness to be vulnerable in public, in a sport that rewards stoicism, changed the conversation about what athletes owe to themselves versus their audience.
Osaka will be competing at the 2026 Grand Slams: the Australian Open, Roland Garros, Wimbledon, and the US Open. Check Japan time to convert match schedules to her home timezone.
