The Fukushima nuclear accident spurred expectations in the Japanese public and around the world that Japan would pull the plug on nuclear energy. Indeed, in July 2011 Prime Minister Kan Naoto announced that he no longer believed that nuclear reactors could be operated safely in Japan because it is so prone to devastating earthquakes and tsunami; by May 2012 all of Japan's 50 viable reactors were shut down for safety inspections. Plans to boost nuclear energy to 50% of Japan's electricity generating capacity were scrapped and in 2012 the government introduced subsidies to boost renewable energy. Incredibly, an aroused public took to the streets in the largest display of activism since the turbulent 1960s as the summer of discontent featured numerous demonstrations involving hundreds of thousands of anti-nuclear protestors. Moreover, public opinion polls indicate that more than 70% of Japanese want to phase out nuclear energy by 2030.
