During both of these tournaments in New York, Osaka drew attention for her activism. She had initially withdrawn from the Cincinnati Open before the semifinal to raise awareness for the police shooting of Jacob Blake, only staying in the tournament after they chose to support her cause by postponing the event for a day. At the US Open, Osaka walked onto the court for her seven matches wearing a different black mask, each of which with the name of an African American who had been killed in recent years often without significant repercussions.
