Hundreds of Japanese have protested at a Tokyo park to demand an end to atomic power — vowing never to give up their fight despite two years of little change after the nuclear disaster in Fukushima, northeastern Japan.

The protesters gathered Saturday ahead of the second anniversary of the March 11 quake and tsunami that sent Fukushima Dai-ichi plant into multiple meltdowns.

Demonstrators said they would never allow the world's worst nuclear catastrophe since Chernobyl to be forgotten, while expressing alarm over the government's eagerness to restart its nuclear power reactors.

Only two of this nation's 50 working reactors are back online, partly because of continuous protests like Saturday's, the first time such demonstrations have popped up in Japan since the 1960s movement against the Vietnam War.
