Tamaki was then in high school while her future husband was in college. The two dated in secret for years. After her family knew, they didn’t speak to her for about a decade and a half. Tamaki’s family reconnected with their daughter only in 2008.

Francois was among the early wave of foreigners coming to Sapporo around 1990.

Tamaki’s Family Were Against Her And Leonard Francois’ Relationship

As per the reports, Francois had to undergo a lot of trouble marrying his now-wife Tamaki, simply because he was black. At the time, Leonard was then one of only a handful of black men in all of Hokkaido.

And at the meantime, as per Tamaki, her parents were already in the matchmaking process that would lead to her arranged marriage.

Tamaki's family were against her relationship with Leonard Francois.

But after her family knew she was dating a foreigner who also happened to be black, her father erupted in outrage. He then excoriated her for bringing disgrace to the family. The coastal town of Nemuro then still followed Tokugawa’s decree from the 1630s — to maintain a racially pure Japan.

Francois & His Spouse Moved To Osaka And Gave Birth To Naomi And Her Sister

After the fallout, the couple moved south to Osaka. There they improved their Japanese and found work. They also became parents to Mari. 18 months later they had Naomi. They welcomed Naomi while still in Osaka. Mari was born in 1996 and Naomi in 1997.

The couple, when Naomi was 3, moved to Long Island to live with Francois’ family.

Naomi Osaka's father started teaching her tennis when she was three.

Then in 2006, Leonard along with his wife and children moved to Florida in order to give his daughters better training opportunities.

Their eldest daughter, Mari was a tennis player until March 2021. Announcing her retirement, Naomi’s sister wrote,

“I am retired from playing tennis. It was a journey which I didn’t enjoy ultimately but I’m grateful for all the memories and support I’ve gained and received over the years from the sport.”

Mari quit tennis because of several injuries she faced throughout her career.

Why Leonard Francois Didn’t Give His Last Name To His Daughters?

Francois and his wife, Tamaki gave their two girls the latter’s family name for practical reasons when the family lived in Japan.

It was primarily for enrolling in schools and renting apartments. But as Leonard’s daughter grew up in America, their name would become a constant reminder of the homeland that they would one day represent.

What Led Him To Teach Tennis To His Daughters?

Leonard says he was inspired by the Williams sisters’ father, Richard Williams to teach tennis to his own daughters. He had watched the Williams girls compete at the 1999 French Open. Having little experience as a tennis player himself, he sought to emulate how Richard trained his daughters to become two of the best players in the world.

In an interview, François said “the blueprint was already there. I just had to follow it.”

It was during one evening in 1999 when his girls were just toddlers. He heard Venus and Serena Williams, then 18 and 17, teaming up to win the doubles title that year.

He thus began coaching Naomi and Mari once relocating to the United States. The former was then three.

After moving to Long Island, he got access to a gym and free public courts and was able to initiate his plan to train his daughters in earnest. With the help of instructional books and DVDs, he made the girls hit hundreds, then thousands, of balls per day.

Why Leonard And His Wife Decided Naomi Would Play For Japan?

Although Osaka grew up in the United States, Francois, and his wife decided she and her sisters would represent Japan. They explained, “We made the decision that Naomi would represent Japan at an early age. She was born in Osaka and was brought up in a household of Japanese and Haitian culture.”
