In the article, the outlet explains that Sakaguchi was dating the hairdresser but at the same time, implied some sort of relationship between the actor and Mei Nagano while the relationship was going on.
This sparked major reactions from fans due to Mei’s own history with relationships. Earlier in the year, the actress was accused of having an affair with married actor Kei Tanaka and two-timing with a Korean actor while in a relationship. Many tried to connect the links of the relationship and hit back at how Sakaguchi had a clean image among fans, which has been ruined.

Mei showing up everywhere is just too funny.
So, does this mean #NaganoMei was dating Sakaguchi Kentaro, while also seeing a Korean actor, and even went to a Halloween party with Kei Tanaka 🤔 #坂口健太郎 #SakaguchiKentaro #永野芽郁 pic.twitter.com/dOTb9ykVAX— tonboriday (@tonboriday) September 10, 2025
