Naomi Osaka’s Mother Goes Viral at the US Open: Who Is Tamaki Osaka?

Naomi Osaka is one of the biggest names at the US Open, but this year another member of the Osaka family is attracting plenty of attention in New York. Her mother, Tamaki Osaka, has become a talking point among tennis fans after making several stylish appearances while supporting her daughter.

From a striking red dress and black gloves during Naomi’s practice session to a sophisticated gray suit, white shirt and silver tie during Naomi’s second-round match, Tamaki has brought her own sense of style to Flushing Meadows.

Who Is Tamaki Osaka?

Tamaki Osaka is Naomi Osaka’s mother and has been an important figure throughout the four-time Grand Slam champion’s life and tennis career. Originally from Japan, Tamaki has remained a familiar source of support for Naomi during major stages of her career.

Although Naomi is the global tennis star, Tamaki has occasionally stepped into the spotlight herself, particularly through her appearances at tournaments. Her presence at the 2026 US Open has once again put the family story in front of a worldwide audience.

Tamaki Osaka’s Viral Red Dress at the US Open

The first major fashion moment came on August 27, when Tamaki was photographed watching Naomi practice at the USTA Billie Jean King National Tennis Center.

She wore a fitted red minidress with matching red lipstick, long black gloves and red earrings, completing the look with oversized sunglasses and Swarovski-adorned Nike Air Max Plus sneakers. The combination quickly caught the attention of fans and media covering the tournament.

Her Gray Suit and Silver Tie Look

Tamaki made another memorable appearance during Naomi’s second-round match against Katerina Siniakova on September 3.

This time, she opted for a completely different aesthetic: a gray jacket, white dress shirt and silver tie. As temperatures rose in New York, she later removed the jacket and loosened the tie while continuing to watch from the stands.

Naomi went on to defeat Siniakova 6-2, 5-7, 6-1 and reach the third round of the US Open. Tamaki’s appearance became one of the memorable off-court moments surrounding the match.

Where Does Naomi Osaka’s Love of Fashion Come From?

The victory over Siniakova sent Osaka into the third round, where she continues her bid for another deep run in New York. Her tennis remains the main attraction, but her fashion and family story have also helped make her one of the tournament’s most discussed players.
