Naomi Osaka has long treated her walk onto court as a stage for self-expression. At Wimbledon, she used it to honor where she comes from.

A kimono for the lawn

For her opening match on Monday, Osaka wore an all-white outfit inspired by the kimono, created by the Tokyo-based designer Yagi Hana and made in part from vintage Japanese garments, Olympics.com reported. The design drew on traditional Japanese craft and on the floral imagery of the All England Club itself — a deliberate blend of two worlds, rendered entirely in white.

That choice of color was no accident. Wimbledon enforces the strictest dress code in tennis, requiring players to compete in almost entirely white clothing, a rule that stretches back to the Victorian era. Rather than chafe against it, Osaka worked within it, finding room for a personal statement inside one of sport's most rigid traditions.

Why she did it

Osaka, who is of Japanese and Haitian descent and represents Japan, said the outfit was about identity. "My Japanese heritage means a lot," she said, according to broadcasters at the tournament. "And they say all white at Wimbledon, and I thought it would be really cool to come out in a kimono."

She also reached for an unexpected reference point: cinema. Osaka said one of her favorite films is "Kill Bill," singling out Lucy Liu's character O-Ren Ishii, who appears in a striking white kimono — a nod that tied a pop-culture flourish to a deeply personal tribute.

A winning debut

The look was matched by the result. Osaka beat France's Elsa Jacquemot 6-1, 7-5 to reach the second round, a confident start for a four-time Grand Slam champion and former world No. 1 who has been rebuilding her career since returning to the tour after the birth of her daughter.

For Osaka, the afternoon underlined something she has shown throughout her career: that what an athlete wears can be a message as much as a uniform — here, a quiet celebration of heritage on the lawns of the sport's most tradition-bound stage.
