Monday, Sept. 19, was Respect for the Aged Day in Japan. But on that sweltering national holiday, it wasn't the heat that that drew tens of thousands of people to Meiji Park in central Tokyo, but their concerns for all the nation's citizens, and others, who may face a threat from nuclear power.

Addressing that huge and peaceful gathering, the renowned freelance journalist Satoshi Kamata typically pulled no punches when he stepped up to the microphone on stage and declared: "Human beings cannot live with nuclear power. This fact has been proved in Hiroshima, Nagasaki and Fukushima. Can we allow more people to become victims of nuclear power?"

When he followed his own question with a resounding "No!" the shouts and applause from the more than 60,000 demonstrators estimated to be there rang out like a clarion call for the abolition of nuclear power. But it was a call tinged with anger about the ongoing crisis 200 km to the north at the Fukushima No. 1 nuclear power plant that was crippled after the Great East Japan Earthquake on March 11.
