Dozens of major Japanese companies have pulled their commercials from broadcaster Fuji Television amid allegations company officials tried to cover up a sex scandal involving one of the country’s most famous TV hosts.

Japanese TV network Fuji faces mass advertiser exodus after allegations of covering up sexual assault claims against host Masahiro Nakai of SMAP fame.

One of Japan’s biggest pop stars and best-known TV hosts, Masahiro Nakai, announced his retirement Thursday, Jan. 23, over sexual misconduct allegations, reports said, in the latest scandal to rock Japan’s entertainment industry.

Nakai’s decision came following reports that he engaged in non-consensual sexual activity with a woman that led to a settlement with the victim.
