The niece of Johnny Kitagawa, the late J-pop mogul accused of sexually abusing hundreds of boys and young men over decades, apologised on Thursday for the abuse he carried out and stepped down as the head of the talent agency her uncle founded. Kitagawa, who died in 2019 aged 87, headed the most powerful talent agency in Japan’s pop music industry and the scandal, which emerged fully earlier this year, has horrified the country.
