Her personal history quoted from U〇A today as attached:

<Osaka’s mother is Japanese, and her father is Haitian. She was born in Osaka, Japan, but raised in America — New York and Fort Lauderdale are home. As a result, she has dual citizenship and chose to represent Japan.

USA TODAY Sports’ Nick McCarvel spoke with Osaka about her background last year:

Osaka, who was born in Japan but raised in the United States, speaks barely any Japanese.

And she could be the next great superstar in Japanese tennis.

“I can understand way more Japanese than I can speak,” Osaka tells USA TODAY Sports in an interview. “And when I go to Japan people are confused. From my name, they don’t expect to see a black girl.” …

When she began to develop into a top-rate tennis player a few years ago, her father, Leonard Francois, chose the Japanese Tennis Association over the United States Tennis Association because of Naomi’s dual passport. She’s played under the Japanese flag ever since.

“It’s interesting,” Osaka, 18, says of the arrangement. “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.”

Perhaps there is one person who can relate. Her older sister, Mari Osaka, also plays professionally, though she hasn’t reached the same heights.

Her first breakthrough came last year
Osaka has never won an professional tournament, but she made waves with a couple finals spots on the lower tours in 2015.

Then in 2016, she started beating the big shots. She made the third rounds of the Australian and French Opens in her first two appearances in the main draws of Grand Slams. But her biggest milestone was reaching the final of Tokyo’s Toray Pan Pacific Open in September 2016, losing to Caroline Wozniacki after beating Dominka Cibulkova, Elina Svitolina and more.>>
