Nagano Mei And Tanaka Kei Caught In Infidelity Scandal

Japanese actress Nagano Mei, 25, has found herself at the center of a scandal involving alleged infidelity with 40-year-old actor Tanaka Kei, who is married with two children. On April 23, 2025, the magazine Weekly Bunshun reported the affair, publishing photographs of the two together, raising eyebrows across Japan.

The pictures, taken outside Nagano's residence, show the pair wearing masks as they enter the same vehicle. This revelation has sent shockwaves through the entertainment industry, particularly as Tanaka is known for his family man image, having married in 2011 and being described as a "devoted husband" and "father of two daughters." The scandal is further complicated by claims that Nagano has also been romantically linked to a Korean actor, who starred alongside her in the same project.

Tanaka and Nagano both featured in the film Greego Baton is Passed On, which was released in Korea in July 2024. In this film, Nagano portrays Tanaka's stepdaughter, adding a layer of complexity to their off-screen relationship.

Following the publication of the affair allegations, Tanaka spoke to the media, stating, "It can't be a romantic relationship. It's not going to happen." However, his comments only fueled speculation, particularly when he was pressed about his interactions with Nagano in April. He initially denied meeting her, then backtracked, saying, "No, we are close friends." When asked about rumors of them spending the night together, he admitted, "That didn't happen. I'm sorry. That was my mistake." Tanaka's remarks have left many confused, especially as he was also questioned about having a key to Nagano's house, to which he insisted, "I didn't have a key," but later contradicted himself by saying, "I'm lying. I'm completely lying."

The fallout from the affair rumors has not only affected Tanaka and Nagano but has also drawn in Kim Mu-joon, a Korean actor who is currently working with Nagano in the TBS drama Casester, which premiered on April 13, 2025. Kim's agency was quick to deny any romantic involvement, stating, "Kim Mu-joon and Nagano Mei are just close colleagues." This clarification comes amidst allegations that Nagano invited Kim to her home, further complicating the narrative.

As the scandal unfolds, social media reactions have been mixed. Many Japanese netizens expressed shock and disappointment, with comments such as, "Did he really cheat?" and "I hope it's not true." Others have criticized Tanaka for his actions, emphasizing that a married man should not engage in such behavior. Some fans have even declared they will boycott any projects featuring the involved parties.

Tanaka's reputation as a family man is now under scrutiny, with many questioning how this alleged affair aligns with his public persona. The news has sparked discussions about fidelity and the pressures of fame, particularly in a culture where family values are held in high regard.

As the story develops, both Tanaka and Nagano have remained relatively silent, with the former facing mounting criticism from the public and media alike. The implications of this scandal extend beyond their personal lives, potentially impacting their careers in a highly competitive industry.

For now, fans and observers alike are left to wonder how this situation will resolve and what it means for the future of these actors in the Japanese entertainment landscape. The intertwining of their professional and personal lives has created a narrative that is both captivating and cautionary, reminding everyone of the complexities that come with fame.
