Osaka will be looking to add an Olympic medal to her accolades. She has already won the Australian Open and the U.S. Open twice. She has yet to win at the French Open or Wimbledon.

It will be Osaka’s first match in a couple of months.

She withdrew from the French Open in the midst of a controversy over her decision to skip press conferences. She said at the time she was going to take a mental health break and later decided to skip Wimbledon altogether to prepare for the Olympics.

In a letter published in Time Magazine, Osaka suggested a different approach to media appearances in an effort to safeguard against athletes’ mental health struggles.

Osaka said she’s not comfortable yet being the "face of mental health" but hopes there are some people who can relate to her and know that it’s "OK not to be OK."
