Three-quarters of Japanese companies have made no changes to sexual harassment policies over the last year and don't plan to do so, a recent poll found, though awareness of harassment is on the rise.

The survey results come after a high-level bureaucrat was toppled in the nation over a harassment scandal, and amid the global #MeToo movement that has forced workplace sexual harassment into national focus.

In the poll, conducted May 9-21, 78 percent of companies said they hadn't strengthened measures to deal with sexual harassment during the last year. A further 77 percent said they weren't even considering changes.
