The mother of Hana Kimura, a cast member from popular reality TV show "Terrace House" who apparently took her own life after being subjected to hateful messages online, has sued a man for posting distressing comments about her after her daughter's death, the mother's lawyers said Wednesday.

Kyoko Kimura filed a lawsuit with the Tokyo District Court on Jan. 22 seeking damages of around ¥2.94 million against the man for causing emotional distress to her family. It is the first damages claim made for hateful comments about Kimura, a professional wrestler who was 22 when she died, according to the lawyers.

The man posted hateful messages about Kimura's death, such as "Everyone is happier that you died, thank you," and "Who do you think you are, causing trouble until the end? Go to hell," in May last year, according to the lawsuit.
