On September 30, actor Megumi Sato (40), who was reported to have had a love affair with Koichi in 2023, left her agency and subsequently deleted her Instagram account, which is becoming a “buzz” among Koichi’s fans. Although Sato has left her agency, no plans for her future activities have been announced. In fact, she has made a big decision without being known to the public. The two have been nurturing their love by avoiding the public eye since their relationship was first reported. After their relationship was reported, the couple nurtured their love by avoiding the public eye. “It must have been no small feat to date Koichi, a top idol. He puts his fans first, and dating outside the home is out of the question. Ms. Sato has had to put up with a lot to preserve their relationship. There was a period of time when he kept his distance from her because he didn’t want to postpone the marriage any longer, but in the end, their feelings never drifted apart. I heard that as a result of Mr. Sato’s “perseverance” in waiting, Koichi reached a major milestone in his career and finally made up his mind to get married. The October 16 issue of “Josei Seven” reported in detail on the marriage announcement of a “junior idol” whom Koichi says he takes as a role model, and the reason why Megumi Sato decided to retire.
