The Japanese entertainment company that has acknowledged its founder sexually assaulted hundreds of boys over the span of half a century, took a new name on Monday: Smile-Up. It also vowed to focus on compensation for victims of the abuse. Tokyo-based Johnny & Associates, founded in 1975, will eventually fold, but its performers can join an independent company that is being set up, said Noriyuki Higashiyama, the company's new leader and a former star at Johnny’s, as the company is known.
