An aerial view shows the Tokyo Electric Power Co.'s (TEPCO) tsunami-crippled Fukushima Daiichi nuclear power plant and its contaminated water storage tanks (top) in Fukushima, in this photo taken by Kyodo August 31, 2013. Japan pledged nearly $500 million to contain leaks and decontaminate radioactive water from the tsunami-crippled Fukushima nuclear plant, stepping up government efforts to cope with the legacy of the worst atomic disaster in a quarter of a century. The announcement comes just days before the International Olympic Committee decides whether Tokyo - 230 km (140 miles) from the wrecked plant - will host the 2020 Olympic Games and the government is keen to show the crisis is under control. Madrid and Istanbul are the rival candidates. Picture taken August 31, 2013. Mandatory Credit. REUTERS/Kyodo (JAPAN - Tags: DISASTER ENVIRONMENT SPORT OLYMPICS) ATTENTION EDITORS - MANDATORY CREDIT.
