Japanese actor Sakaguchi Kentaro has announced his marriage to a non-celebrity woman, but the sudden news has also brought renewed attention to rumors surrounding his past relationships.
On September 6, Sakaguchi personally shared the marriage news through his paid fan club. He revealed that he had married a non-celebrity woman he had been dating. His agency later confirmed the marriage to Japanese media outlets.
Following the announcement, details of the actor’s previous dating rumors and controversies have once again come under the spotlight.

In September 2025, Japanese media outlet Shukan Bunshun published an exposé concerning Sakaguchi’s alleged romantic life. According to the report, the actor was allegedly in a relationship with a hairstylist who was three years older than him. The woman was reportedly living with Sakaguchi at his apartment in Tokyo, and the two were said to have been together for approximately four years.
The outlet later raised further questions about Sakaguchi’s personal life, alleging that while he was reportedly dating the hairstylist, there were also suggestions of a connection between the actor and actress Mei Nagano.

Sakaguchi and Nagano have previously worked together on several projects and also share a connection as PRADA ambassadors.
At the time, Nagano was herself reportedly at the center of another controversial romantic situation involving an alleged relationship with a married man.
Now that Sakaguchi has confirmed his marriage, the previous reports and dating rumors surrounding the actor have resurfaced, drawing renewed attention from the public.
