The sports apparel giant — who signed a sponsorship deal with Osaka in 2019 — applauded the athlete in a statement on Monday for opening up about her struggle with depression.

"Our thoughts are with Naomi. We support her and recognize her courage in sharing her own mental health experience," Nike said.

Osaka's decision to pull out of the competition came after the tournament, also called Roland Garros, fined her $15,000 for not speaking to the media following her first round match on Sunday.
Citing mental health reasons, the four-time major champion announced on Twitter last Wednesday that she would not participate in any news conferences at the tournament. Announcing her subsequent decision to withdraw, she revealed that she has "suffered long bouts of depression" since winning her first Grand Slam title in 2018.

Roland Garros said in a statement that Osaka had failed to honor her contractual media obligations and was fined under the tournament's Code of Conduct. The statement added that Roland Garros had "tried unsuccessfully to speak with her to check on her well-being" and that she was reminded that "rules should apply equally to all players."

"Naomi Osaka's decision reminds us all how important it is to prioritize personal health and well-being," Mastercard (MA) said in a statement. "We support her and admire her courage to address important issues, both on and off the court."

Osaka became the first number, one tennis player, to join Mastercard's roster of global ambassadors in 2019.

Swiss luxury watchmaker TAG Heuer said that it supports its brand ambassadors "in triumph but also during challenging periods."

"Naomi is going through difficult times and we truly hope to see her back soon. She is a great champion and we are convinced that she will come out of this period stronger, be it professionally or personally," the company said in a statement.

Nissin Foods, a Japanese company known for its instant noodles, also released a message of solidarity.
"We pray for Ms Naomi Osaka's earliest recovery, and wish her continue success," a company spokesperson said in a statement.

Nissan, the Japanese automaker, also threw its weight behind Osaka. "We support the right of our ambassadors to express themselves and stand by her decision," the company said in a statement.
All Nippon Airways, a Tokyo-based airline, said that it, too, would continue to support Osaka "as a sponsor."

Sweetgreen, a US restaurant chain of which Osaka is a brand ambassador and investor, said: "Our partnership with Naomi is rooted in wellness in all its forms. We support her in furthering the conversation around mental health and are proud to have her as part of the sweetgreen team."
French Open sponsors Rolex, Engie and Infosys (INFY) declined to comment.
