FILE - In this May 3, 2012 file photo, anti-nuclear activists, Taro Fuchigami, right, Taichi Masakiyo, center, and an unidentified Buddhist monk, stage a hunger strike in a tent in front of Japan's Economy, Trade and Industry Ministry in Tokyo against the government's plan to restart the Oi nuclear power plant in western Japan. The Fukushima crisis is eroding years of Japanese efforts to reduce greenhouse gas emissions blamed for global warming, as power plants running on oil and natural gas fill the electricity gap left by now-shuttered nuclear reactors. Japan will be free of atomic power for the first time since 1966 on Saturday, May 5, when the last of its 50 usable reactors is switched off for regular inspections. The central government would like to restart them at some point, but it is running into strong opposition from local citizens and governments. (AP Photo/Shizuo Kambayashi, File)
