HAMAMATSU, Japan - A woman with visual impairment filed a lawsuit Friday against the Japanese government, demanding it pay 33 million yen ($307,000) in damages for forcing her to undergo sterilization in 1977 under the now-defunct eugenics protection law.

"I want the state to apologize. I wanted to have a third child," Chieko Muto, 71, a resident of the central Japan city of Hamamatsu, told reporters after filing the suit with the Hamamatsu branch of the Shizuoka District Court.

Muto has argued she endured significant mental distress, and that the 1948 law was unconstitutional.
