Growing up, Mika Kasahara saw the nuclear power plant that hugs the coast of her hometown simply as the place where her father worked, a familiar fortress of cooling tanks and steel lightning towers overlooking the Sea of Japan.

"We thought that as long as nothing bad happened, it’s fine,” Kasahara, 45, said.

After the disaster 11 years ago at a nuclear power station in Fukushima Prefecture, where an earthquake and tsunami led to a triple meltdown, Japan took most of its nuclear plants offline. Now, Kasahara, spooked by security breaches and damaged infrastructure at the power station near her home, wants it shuttered for good.
