Kei Nishikori, once ranked among the world’s top tennis players, has found himself at the center of a personal and professional storm. Just days after announcing his withdrawal from Wimbledon due to injury, the Japanese athlete issued a public apology following reports of an affair with model Azuki Oguchi.
Nishikori, 35, has been married to former model Mai Yamaguchi since 2020. The couple, who share two young children, had been together for five years before tying the knot. According to Japanese media, the affair with Oguchi began in 2022 and reportedly resumed last year after a brief hiatus.
The scandal broke after Nishikori was photographed leaving Oguchi’s apartment, prompting widespread media coverage and public scrutiny. In a statement, he expressed deep regret for his actions, apologizing to his wife, children, fans, sponsors, and tennis associations. He acknowledged the pain he caused and pledged to focus on rebuilding trust through his professional efforts.
This was his apology:
“I deeply apologise for causing discomfort to everyone who supports me; tennis fans, tennis associations, sponsors, and other related parties, and for their concern and inconvenience due to my dishonest behavior.
In addition, I deeply regret that I made my wife, children, and each ‘parent’ feel hurt. From now on, in order to fulfill my life as a responsible member of society, I will solely focus on tennis competitions and produce results. We will do our best to regain your trust.”
This controversy comes amid a difficult period in Nishikori’s career. Persistent injuries have plagued his return to form, and his recent withdrawal from Wimbledon marked another setback. Despite these challenges, he emphasized his commitment to tennis and to fulfilling his responsibilities both on and off the court.
The incident has sparked conversation in Japan and beyond, not only about the pressures faced by public figures but also about the intersection of personal conduct and professional reputation in the world of sports. Nishikori’s next steps—both in his career and personal life—will be closely watched.
