the Japanese government was planning to buy some properties from civilians to store waste and materials that had become radioactive after the accidents. Chiaki Takahashi, Japan's foreign minister, criticized foreign media reports as excessive. He added that he could "understand the concerns of foreign countries over recent developments at the nuclear plant, including the radioactive contamination of seawater". Due to frustration with TEPCO and the Japanese government "providing differing, confusing, and at times contradictory, information on critical health issues" a citizen's group called "Safecast" recorded detailed radiation level data in Japan. The Japanese government decided to pump radioactive water to the Pacific after the Tokyo Olympics. International The international reaction to the disaster was diverse and widespread. Many inter-governmental agencies immediately offered help, often on an ad hoc basis. Responders included IAEA, World Meteorological Organization and the Preparatory Commission for the Comprehensive Nuclear Test Ban Treaty Organization. In May 2011, UK chief inspector of nuclear installations Mike Weightman traveled to Japan as the lead of an International Atomic Energy Agency (IAEA) expert mission. The main finding of this mission, as reported to the IAEA ministerial conference that month, was that risks associated with tsunamis in several sites in Japan had been underestimated. In September 2011, IAEA Director General Yukiya Amano said the Japanese nuclear disaster "caused deep public anxiety throughout the world and damaged confidence in nuclear power". Following the disaster, it was reported in The Economist that the IAEA halved its estimate of additional nuclear generating capacity to be built by 2035. In the aftermath, Germany accelerated plans to close its nuclear power reactors and decided to phase the rest out by 2022 (see also Nuclear power in Germany). Belgium and Switzerland have also changed their nuclear policies to phase-out all nuclear energy operations. Italy held a national referendum, in which 94 percent voted against the government's plan to build new nuclear power plants. In France, President Hollande announced the intention of the government to reduce nuclear usage by one third. However, the government earmarked only one power station for closure – the aging Fessenheim Nuclear Power Plant on the German border – which prompted some to question the government's commitment to Hollande's promise. Industry Minister Arnaud Montebourg is on record as saying that Fessenheim will be the only nuclear power station to close. On a visit to China in December 2014 he reassured his audience that nuclear energy
