Farewell at Ariake Coliseum

Kei Nishikori concluded his professional tennis career on Thursday at the Japan Open in Tokyo, falling 6-4, 6-4 to American world number eight Frances Tiafoe in the opening round. The 36-year-old entered the tournament at Ariake Coliseum as a wild-card entrant, having dropped to world number 436 after years of injuries and spending most of the 2026 season on the ATP Challenger tour. Spectators filled the arena for the second match of the day, cheering at the end of nearly every point as the two-time tournament champion took the court one final time. After the match, Nishikori spoke to the crowd during an on-court ceremony to reflect on his competitive mindset.

“I wish I could have put in a slightly more convincing performance. But I'm happy I kept fighting right to the end.”

Career achievements and milestones

Nishikori spent 19 years on the professional tour, capturing 12 ATP titles and earning a career-high ranking of world number four in 2015. He became the first Asian man to reach a Grand Slam singles final at the 2014 US Open, where he defeated then world number one Novak Djokovic in the semi-finals before falling to Croatia's Marin Cilic. That 2014 campaign stood as his most productive season, yielding four ATP titles and a victory at the Japan Open, a tournament he had previously won in 2012. Nishikori was also the second Asian man after Thailand's Paradorn Srichaphan to enter the ATP top 10, and he secured an Olympic bronze medal for Japan at the 2016 Rio Games by defeating Rafael Nadal.

Physical toll and tributes from peers

Injuries interrupted Nishikori's momentum throughout the second decade of his career, limiting his mobility and requiring multiple comebacks. Earlier this season, he acknowledged that he was barely hanging on physically, and in August he played his final Grand Slam appearance in the third round of US Open qualifying, where 20-year-old Japanese compatriot Rei Sakamoto defeated him. Following his final match on Thursday, tournament organisers broadcast a tribute video featuring messages from active and former tour players, including Carlos Alcaraz, Grigor Dimitrov, Alex de Minaur, and Andy Murray.

“Your resilience and your fighting spirit to always come back after all the adversity you had with your body, injuries and everything that you faced is really commendable and admirable.”

Final ceremony and legacy

Tributes also came across social media, where Greek player Stefanos Tsitsipas thanked Nishikori for his aggressive counter-punching style and dedication across two decades. Although Nishikori has played his final competitive match, tournament organisers scheduled an official retirement ceremony for Tuesday, the final day of the Japan Open at Ariake Tennis Park. Nishikori exits professional competition having set the standard for Japanese men's tennis, establishing benchmarks as the country's first male Grand Slam singles finalist and top-ten player.
