Dual Citizenship
Though born in Japan, Osaka has lived in the U.S. since she was 3.
“I grew up in New York until I was 8 or 9 and then I moved to Florida,” shepreviously said.
Osaka’s dual citizenship meant that she had a choice between playing for either country but Francois chose Japan, thinking it would open up more opportunities for her.
Family History
Osaka’s father accused her of bringing disgrace on the family when he learned that she was dating a black foreigner, according to aNew York Timesprofile published in August.
The couple moved to Osaka, Japan’s second largest city and the same name as Tamaki’s surname.
“Everyone who was born in Osaka, their last name is Osaka,” Naomi joked withreportersduring a U.S. Open press conference.
Naomi and older sisterMari, who is also a professional tennis athlete, took their mother’s last name instead of Francois' to assimilate in Japan. “It was mostly a practical matter when they lived in Japan, helpful for enrolling in schools and renting apartments,” the family told theTimes.
Admittedly Far from Fluent
Though she can understand Japanese during conversations with her loved ones and those in her inner circle, Osaka has regularly used English as her way to communicate with the media.
“I can understand way more Japanese than I can speak. And when I go to Japan people are confused. From my name, they don’t expect to see a black girl,” Osaka toldUSA Today Sportsin January 2016.
“I never know what to do when someone asks me where I’m from. I just say FL, because saying Japan starts an unnecessary conversation,” Osakatweetedin May 2017.
Also in herTimesinterview, she explained why it’s important to redefine what it means to be Japanese today.
“It’s interesting. I feel there’s not really anybody like me. It seems like more of a challenge being from Japan. I never thought about the American competition [in tennis]. I just thought about playing tennis,” Osaka said of being biracial.

At age 20, Osaka was able to cross off one of her biggest bucket list items: playing (and defeating) her childhood hero, whom sheonce wrote a 3rd-grade report about.
Not only was the U.S. Open a big deal for her, it was also a monumental moment for her father Francois, who trained Osaka from age 3, and hired coach Sascha Bajin, best known for working as Williams' hitting partner for eight years.
Francois also took inspiration from Williams' father, Richard, in training his two daughters. “The blueprint was already there. I just had to follow it,” Francois told theTimes.
Williams previously praised Osaka. “She’s really young and really aggressive. She’s a really good, talented player. Very dangerous,” Williamssaid at the Australian Openin 2016.
Family’s Disapproval
After Naomi’s mother Tamaki became estranged from her Japanese family when she married and moved away with Francois. After 15 years, following the births of Mari and Naomi, the family reconnected and went to Japan to meet one another but Tamaki’s parents disapproved of how the girls were homeschooled to focus on their tennis careers, according to theTimesprofile.
However, Naomi’s status as a rising star in tennis caught the attention of her grandparents.
“I was simply stunned. I didn’t expect her to become the champion,” grandfather Tetsuo told Japanese newspaperAsahi Shimbunabout Naomi’s U.S. Open victory.
In fact, Naomi called him after beating Williams. “She said, ‘I did it,’ and I said, ‘You did a great job,’ " said the 73-year-old, whose family continues to struggle with unstable power supply and food shortages due to the 6.7 earthquake that rocked Hokkaido on Sept. 6.
Naomi will be returning to Japan to play in the Toray Pan Pacific Open Tennis Tournament in Tokyo, which starts on Sept. 17. Tetsuo plans to travel to Tokyo to cheer on his granddaughter.
Hobbies Off the Court
In addition to being a big fan of Beyoncé, she’s also a big fan of video games.
In July, Osaka shared a photo of herself and sister Mari, who is one year older, at the finals of the e-sports tournament Overwatch League, which was held in Brooklyn’s Barclays Centre this year.
The Overwatch League is a professional tournament held for the video game Overwatch.
Bright Future
With a multicultural background and a furious forearm, Osaka is well positioned to become an international celebrity. And she has no plans of slowing down anytime soon.
In 2016, she opened up about her career goals, telling theBBC, “To be the very best, like no one ever was,” even jokingly adding, “That’s a Pokemon quote, I’m sorry. That’s the Pokemon theme song.”
And when asked why she had so many fans cheering her on at theAustralian Openthat same year, she explained: “Probably because they think I’m interesting. Maybe it’s because they can’t really pinpoint what I am, so it’s like anybody can cheer for me.”
