Moves by broadcaster NHK, McDonald’s, Nissan and Suntory follow allegations against late Johnny & Associates founder

Some of Japan’s best-known companies have cut ties with a powerful talent agency whose founder was accused of sexually assaulting hundreds of teenage boys, in a scandal that has rocked the country’s entertainment industry.

The public broadcaster NHK said this week it would not sign new contracts with stars from Johnny & Associates until it was convinced the firm had properly addressed the scandal.
