When the late Shizuko Sakata started distributing the newsletters she wrote in Nagano Prefecture more than 30 years ago to campaign against nuclear power, her daughter, Masako, was not fully supportive.
"I thought her doubts over nuclear power plant safety might have been fair, but I had more belief in comments by scientists saying that safety issues had been sufficiently examined," said Masako Sakata, 63.
But amid the nuclear disaster at the Fukushima No. 1 power plant, she recently reread the newsletters, called "Please Listen," and realized that the fears of her mother, who died in 1998 at age 74, had actually come true.
