Showa Denko
The Niigata lawsuit was ultimately successful, and on 29 September 1971, the court found Showa Denko guilty of negligence. Families of deceased and congenital patients received JPY10 million, surviving patients were awarded between JPY1 million and 10 million depending on symptoms, JPY400,000 to those contaminated by mercury, and JPY300,000 were awarded to pregnant women who had been told to have abortions due to the danger posed to their unborn children.
