Fuji TV also denied a report by the Shūkan Bunshun that one of its employees set up the date between Nakai and the woman. Shortly after an affiliate of American activist fund Dalton Investments (a minority shareholder of Fuji Media Holdings) sent an open letter to Fuji TV calling on their board to open an independent investigation and alleging that its handling of the Nakai matter exposed "serious flaws" in their corporate governance, Fuji TV president Koichi Minato apologized over the allegations and announced that an investigation panel consisting of third-party lawyers would be established. Minato added that while the network was aware of the incident in June 2023 between Nakai and the woman, it was not disclosed in the interest of the woman's privacy and her physical and mental recovery.
