The mother of Hana Kimura, a former cast member of the popular reality TV show "Terrace House," said Thursday she will file a lawsuit next year against the show's Japanese broadcaster and a production company seeking compensation for the suicide of her daughter.

Speaking at a news conference in Tokyo with her lawyer, Kyoko Kimura said she wanted Fuji Television Network Inc. and the production company to "sincerely" investigate the reason for her daughter's suicide, adding that a week or so before her death, Hana had said the producers "don't treat the cast like human beings."

Hana Kimura, 22, was among the six cast members of the 2019-2020 season of "Terrace House Tokyo." The professional wrestler was found dead at her apartment in Tokyo in May 2020 after becoming the target of a barrage of hateful messages on social media. The show has since been canceled.
