Naomi Osaka Battles Illness as 2026 Season Kicks Off

Naomi Osaka started her 2026 tennis season with a challenging setback at the United Cup, where she faced a straight-sets defeat against Maria Sakkari, losing 6–4, 6–2. The former world No. 1 acknowledged that she is still recovering from health issues that have affected her performance, a sentiment shared by former British player Laura Robson. As Osaka reflects on her difficulties, she remains hopeful for a successful return to form ahead of the Australian Open later this month.

Health Struggles Affect Performance

In a post-match press conference, Osaka revealed that she has been grappling with lingering illness since the winter break. She described experiencing symptoms such as coughing, congestion, and fatigue, indicating that her condition likely began before Christmas Eve. Although she believes she is nearing full recovery, Osaka admitted that she is not yet at her optimal level of fitness.

“I’m determined to improve every day,” Osaka said, expressing optimism that her health will allow her to compete effectively when the Australian Open begins on January 18, 2026. Despite the challenges, she remains focused on returning to the court and performing at her best.

Looking Ahead to Upcoming Competitions

Osaka is set to compete again at the United Cup on January 4, 2026, where her team, Japan, will face Great Britain. If her health permits, she is expected to meet British No. 1 Emma Raducanu, in a highly anticipated rematch following their encounter at the 2025 Washington Open, where Raducanu emerged victorious.

The two-time Australian Open champion has a remarkable track record in Melbourne, having won 79% of her matches at the tournament. Osaka claimed the title in 2019 and 2021, and she is determined to challenge for another major title this year. As she navigates her recovery, the focus now shifts to her upcoming matches and the potential for another memorable performance at one of tennis’s most prestigious events.
