TOKYO — Japanese actor and model Kentaro Sakaguchi has announced that he is married, surprising fans with news that he quietly tied the knot with a non-celebrity woman he had been dating.
Sakaguchi, 35, announced the marriage on his paid fan-club website on Sept. 6, 2026, telling fans that he had married a woman outside the entertainment industry.
His management agency, Tristone Entertainment, subsequently confirmed the marriage but did not disclose the identity of his wife or provide details about when their relationship began.
A private announcement from one of Japan’s most recognizable actors
Sakaguchi chose to share the news directly with members of his fan club rather than make a large public announcement.
In his message, the actor acknowledged that the marriage was a private matter and said he had married a non-celebrity woman he had been dating.
He also indicated that he intends to continue working hard as an actor.
The low-key announcement is consistent with the couple’s decision to keep details of their relationship and married life away from the public eye.
There has been no official disclosure of his wife’s name, occupation or other personal details.
Marriage comes after a year of relationship controversy
The announcement arrives roughly a year after Sakaguchi became the subject of intense Japanese media attention over his reported romantic relationships.
In September 2025, Shukan Bunshun reported that Sakaguchi had been in a long-term relationship with a hair and makeup artist identified only as “A.”
According to the publication, the pair had reportedly dated for around four years and lived together in a Tokyo residence. The report also said that they had been introduced to each other’s friends and parents.
The same report alleged that Sakaguchi was also romantically involved with actress Mei Nagano during the period of his relationship with A.
Those reports triggered widespread discussion online and put Sakaguchi’s private life under considerable scrutiny.
It is important, however, to distinguish between media allegations and confirmed facts. The reported relationship claims were published by Shukan Bunshun and subsequently covered by other media; Sakaguchi’s marriage announcement does not independently confirm those allegations.
Identity of his wife remains private
Sakaguchi and his agency have not publicly identified his wife.
That means speculation about whether the woman he married is the same person described in previous media reports should be treated cautiously.
Japanese coverage has noted that the actor’s announcement simply described his wife as a non-celebrity woman he had been dating, without providing further identifying information.
For now, the couple appears to be keeping their marriage largely out of the spotlight.
From model to leading actor
Sakaguchi first became known as a model before establishing himself as an actor.
He made his acting debut in 2014 and subsequently built a successful career in Japanese television and film.
Among his better-known projects is the 2018 television drama Signal: Choki Mikaiketsu Jiken Sosahan, as well as the 2024 romance drama What Comes After Love, in which he starred alongside South Korean actress Lee Se-young.
His combination of modeling work and acting has made him one of the more recognizable Japanese entertainment figures among audiences across Asia.
Career continues despite the personal spotlight
Sakaguchi’s marriage announcement comes as he continues to take on new acting projects.
He is set to appear in the upcoming crime drama Kidnap Game, alongside South Korean actor Lee Joon-gi and Singaporean actress Carrie Wong.
The series is scheduled to premiere on Oct. 6, 2026.
That means the actor’s personal milestone comes just weeks before another major professional appearance.
Rather than stepping away from the spotlight, Sakaguchi has indicated that he plans to continue focusing on his acting career.
Fans react to the surprise news
For fans, the announcement was notable because Sakaguchi had kept his personal life relatively private.
The fact that he revealed the marriage through his fan-club platform also gave the announcement a more personal tone, allowing him to communicate directly with supporters.
The timing, however, inevitably brought renewed attention to the relationship reports that had surrounded him the previous year.
Still, the confirmed news at this point is simple: Kentaro Sakaguchi is married.
The identity of his wife and the details of their relationship remain private.
A new chapter for Kentaro Sakaguchi
At 35, Sakaguchi enters a new chapter of his personal life while continuing to build his career in Japanese entertainment.
The actor has chosen not to publicly disclose extensive details about his marriage, and his agency has respected that privacy.
For an entertainer whose relationships have previously attracted intense media attention, the decision to keep his wedding and family life private may be particularly significant.
What comes next professionally is already clear: new acting projects, including Kidnap Game, are on the horizon.
For now, however, Sakaguchi’s biggest announcement is personal.
The actor has married—and he is asking fans to respect the private life he is beginning with his new wife.
