Osaka stars in Beats by Dr. Dre "Flex that" campaign

Naomi Osaka may be in the off-season, but it doesn't seem like she's taking much of a break. Between advocating for social justice and launching her first Nike apparel line, the world No. 3 has been very busy.

Most recently Osaka appeared in a powerful Beats by Dr. Dre ad campaign that digs deep into common misconceptions and hypocrisies surrounding Black culture all while celebrating it.

On Thursday, she unveiled a new Beats by Dr. Dre ad on Instagram. The 30-second clip showcases the Beats Flex earphones while giving a glimpse into Osaka's pre-match routine.

"As a kid growing up I never really talked, I was the quiet one (honestly still am lol), I was the one that wanted to just skate by unnoticed and conflict-free," Osaka wrote on Instagram. "But the beauty of growing up is learning and seeing things for yourself, one of the things I’ve learned is that everyone has a platform and how they use it is their responsibility."

Osaka stretches, fixes her hair and grabs her tennis bag all while listening to boyfriend and Grammy nominated rapper Cordae's unreleased song "The Parables".

Osaka's video ad for the new earphones is a part of Beats by Dr. Dre's "Flex that" campaign, which is all about taking a stand against racial inequalities, and inspiring youth to use their platforms to ignite change and make the world a better place.

The three-time major champion walks out towards the court for what appears to be a match, with her long hair trailing behind her, and the words "silence is violence" beaded into her braids.

This year, the 23-year-old has grown up immensely, not just as a player, but also as a person. When Osaka first appeared on the scene, she was reserved and timid. This year, Osaka picked up her second US Open title while using her voice and platform to raise awareness for social injustices in the United States.

"As I grow more I will learn more things, but at the moment I can only hope I’m using my platform well," Osaka wrote.

While Osaka says she still believes she is the quiet one, she hopes to continue to make a difference using her voice and social media platforms.
