Which Japanese player won US Open women's singles titles in 2018 and 2020?

Naomi Osaka won the US Open women’s singles titles in 2018 and 2020.

Osaka captured her first major in 2018 by defeating Serena Williams 6–2, 6–4. That victory made her the first Japanese player to win a Grand Slam singles title and announced her as one of the sport’s leading young players. Two years later, she won the US Open again, beating Victoria Azarenka 1–6, 6–3, 6–3 after recovering from a set down.

The two championships had very different stories. The 2018 final was Osaka’s first major final and was marked by intense attention surrounding events involving Williams and the chair umpire. The 2020 final was played during the COVID-19 pandemic and followed Osaka’s withdrawal from the preceding Cincinnati final because of a hamstring injury.

Osaka also won the Australian Open in 2019 and 2021, giving her four major singles titles. Her US Open victories are sometimes mixed up with her Australian Open wins, but her New York titles came specifically in 2018 and 2020.
