In a scandal that has rocked the Japanese entertainment industry, popular actors Tanaka Kei and Mei Nagano are facing intense scrutiny following allegations of an affair, which were brought to light through leaked LINE messages. The revelations, first reported in the April 24, 2025 issue of Shukan Bunshun, have led to a significant backlash against both actors, particularly Nagano, who has built her career on a wholesome image.
The situation escalated on May 8, when Shukan Bunshun published a follow-up report detailing explicit exchanges between Tanaka and Nagano, further fueling public outrage. Despite both actors' agencies denying any intimate relationship, stating there was “no intimate relationship,” the leaked messages have cast a shadow over their reputations. According to a sports paper reporter, “After the first report, both agencies issued comments, but the second report revealed shocking content that has dominated discussions online.”
Public reaction has been swift and severe, with many calling for Nagano's removal from advertisements. Comments on social media have included demands for her to step down from all commercials, as one user lamented, “I hope Mei Nagano drops all her commercials; this is disgusting.” Others have pointed fingers at Tanaka, suggesting he is the more culpable party, with one comment reading, “Tanaka is the worst for saying sweet things and not leaving his wife.”
Despite the turmoil, Nagano has continued her busy work schedule, appearing on her radio show, Mei Nagano's All Night Nippon X, without interruption. She is also starring in the TBS Sunday drama Caster, where there are currently no plans to alter the cast or cancel the show. On May 6, she even made an appearance on the Nippon Television variety show The! World's Astonishing News, which surprised many viewers given the ongoing scandal.
As the fallout continues, advertising companies have begun to react. Suntory, a major daily goods manufacturer, confirmed on May 9 that they had removed all images and videos of Nagano from their website following the scandal. A representative stated, “We are making a comprehensive judgment on various impacts and proceeding with our review,” indicating that the company is assessing the situation's implications on their brand. Similarly, JCB has also taken steps to remove Nagano's commercials from their site, citing ongoing fact-checking regarding the allegations.
The swift removal of Nagano from advertisements has raised eyebrows, particularly as her agency has consistently denied the affair allegations. Industry insiders speculate that the ongoing reports and the nature of the allegations have made it impossible for companies to continue featuring her without risking damage to their own reputations. As one advertising agency representative noted, “The longer this scandal drags on, the worse the consumer perception will become, forcing companies to take action.”
On the other hand, both Tanaka and Nagano's agencies have publicly stated their confidence in their clients. Nagano's agency commented that they had confirmed with her that the reported messages were fabricated, while Tanaka's agency echoed this sentiment. However, skepticism remains among fans and observers, particularly as the public has noted the absence of legal action against the media for the allegations. Comments on social media reflect a growing distrust, with many asserting that the lack of legal recourse suggests a deeper truth to the allegations.
Adding to the complexity of the situation, Tanaka is also reported to be involved in another affair with Korean actor Kim Mu-jun, further complicating his public image and potentially impacting his career. The dual allegations have led to heightened scrutiny of both actors, with fans expressing disappointment and anger over their actions.
As the scandal unfolds, it remains to be seen how both actors will navigate their careers in the aftermath. While Nagano continues to work, the long-term implications of these allegations on her public image and career trajectory are uncertain. Advertising partners and fans alike are watching closely, and the pressure is mounting for both Tanaka and Nagano to address the situation head-on.
The scandal has not only affected the actors involved but also raised questions about the broader implications for the Japanese entertainment industry, particularly regarding how public figures manage their personal lives in the age of social media and instant communication. As the situation develops, it will be crucial to observe how both Tanaka and Nagano respond to the allegations and whether they can restore their reputations in a landscape increasingly intolerant of scandal.
In the world of celebrity, where public perception can change overnight, the fallout from this scandal serves as a stark reminder of the delicate balance between personal lives and public personas. As fans, sponsors, and the media continue to react, the future remains uncertain for both Tanaka and Nagano, with many wondering if they can emerge from this controversy unscathed.
