Japanese actress Nagano Mei is facing fallout from a dating controversy that has shaken the entertainment world.
Reports emerged on April 23 alleging that Nagano, known for her role in the J-Drama series "Caster," has been two-timing with her co-star, Korean actor Kim Moo Jun, and married Japanese actor Tanaka Kei.
Kim, who is reportedly 15 years older than the 25-year-old actress and has two children, has denied any romantic involvement through his agency.
Despite these denials, the controversy has led to significant changes in the show's production.
Although Nagano remains with "Caster," insiders report that her screentime is being reduced.
"The show will continue airing as scheduled, but producers are shifting focus," a source close to the production said.
This shift is resulting in more prominence for Michieda Shunsuke, who plays the third lead character.
Industry insiders also tell Tokyo Sports that sponsors and networks are closely monitoring public reaction.
A production staff member said, "Viewers might start linking her character's integrity with the headlines," hinting at a possible shift in focus within the drama.
Reports suggest that Naniwa Danshi's Shunsuke Michieda may be receiving a larger role as a result.
Caster centers on the ethics of journalism, starring Hiroshi Abe as a relentless news anchor aiming to uncover the truth.
Nagano plays a passionate news director whose fiery dialogue from episode one — accusing Abe's character of "breathing lies" — has taken on new meaning amid the rumors.
The scandal has sparked widespread conversation, with many questioning the personal lives of those in the public eye.
"Her loss is his gain," a commenter noted, referring to Shunsuke's increasing role.
Those familiar with Nagano say her friendly nature with co-stars sometimes leads to misunderstanding.
"She's open and often invites senior actors out for dinner. It's all innocent but can blur lines," a source said.
Tanaka has been married since 2011 and has two daughters. Known for his casual nightlife persona, he has faced previous rumors without impact.
Advertising experts note Nagano carries more risk due to her high profile; she ranked in last year's top 10 for endorsements, while Tanaka's commercial presence has dwindled.
Despite the controversy, Nagano remains in demand.
She is set to appear in the film Kakukaku Shikajika, premiering May 16, and will star in NHK's upcoming historical drama Toyotomi Brothers! Scheduled for 2026.
Time will tell if these headlines will have an impact on her career in the long run.
Nagano has not publicly commented on the allegations.
In the meantime, industry experts are left guessing as to how this may threaten not only her career but also future projects altogether, amidst the competitive entertainment field.
