From Wikipedia: “In January 2016, Becky’s reputation as Japan’s most popular female personality took a negative hit after Japanese tabloid Shukan Bunshun revealed that she had an affair with musician Enon Kawatani who at the time was married. Following the scandal, Kawatani announced that he officially divorced his wife. In order to appease the public backlash and as a condition for her comeback to show business in Japan, Becky tried to officially apologize to Kawatani’s wife. However, having no direct channel to her, Becky contacted the Shukan Bunshun’s editorial department instead. Shukan Bunshun published the full contents of Becky’s letter at the end of April 2016.[10] The letter acknowledges her affair but also implies that she has not seen Kawatani since the scandal broke and that she no longer has feelings for him. As a result of her apologies, Becky was to make her comeback with an appearance on TBS. In her first appearance back on TV, she appeared on “Full Chorus – Music is Full Chorus” on the cable channel BS Skyperfect TV.[11]”
The Guardian: “Her crime, it appears, was to break the steadfast rule that requires young female celebrities in Japan not only to entertain, but to remain morally unimpeachable.”
