Top politicians in Japan have spoken up about the need to deal with cyberbullying following the death of Hana Kimura, who apparently killed herself after facing hundreds of hateful messages online.

Kimura, a 22-year-old pro wrestler and star of the popular reality show “Terrace House,” is believed to have taken her own life at the Tokyo home where she was living alone, sources said Monday. Several suicide notes were found in her room.

One note was addressed to her mother, saying "Thank you for giving birth to me," according to the sources. Her death was confirmed at a hospital.
