[1] is a Japanese rapper, singer, actor, dancer, and a member of the J-pop group AAA. He is the rapper of the group and also writes rap lyrics for the band. He is also a member of the hip hop trio Mother Ninjas. He also debuted as a solo artist in August 2013 as Sky-Hi.[2]
On December 19, 2025, News Post Seven reported that Hidaka had had late-night meetings with a 17–year–old female idol at his home, dating back to around 2023, when she was 15, after Hidaka DM'd her. The idol had reportedly boasted about their connection to her acquaintance. News Post Seven reviewed the LINE messages Hidaka sent her, where he said, "(you are) so cute, I am dying," "(you are) so my type it is painful." News Post Seven quoted the idol's mother saying she didn't allow the meetings and wasn't aware of the recent visits, but later her father reached out to News Post Seven to say the parents gave her/him permission for meetings to seek music-related career advice.[3] In Tokyo, taking a minor under the age of 18 out late at night without parental consent or a legitimate reason may constitute a violation of youth protection and development ordinances. [4] On December 19, 2025, BMSG, a music agency where Sky-Hi serves as CEO issued an apology with an official statement addressing recent media reports and announced internal measures for governance reform. On the post, the agency informed that they were aware of consent from the minor's guardian, but that the time of the meeting was inappropriate. They added that they would implement compliance awareness and sincerely work to restore trust so that such a situation did not occur again. Hidaka appeared on his radio program later, but did not talk about the issue.[5]
On December 25, 2025, Sky-Hi/BMSG put out another statement, announcing a fundamental review of the management structure and the strengthening of corporate governance, the introduction of an independent and objective audit function covering all officers and employees, including executive leadership, the re-establishment of a strong compliance culture and the development of robust internal control systems and the restructuring of the management framework as well as cancellation of a live show planned for December 27th and a TV appearance planned for December 29th.
