Japan earthquake and tsunami anniversary: Japan suppressed key radiation report Four days after the Great East Japan Earthquake, Yoshiaki Takaki, the then-science minister, met with senior members of the government and ministry officials and decided not to release to the public data from the national System for Prediction of Environmental Emergency Dose Information (SPEEDI), according to leaked internal documents. Predictions on the amount of radiation that had already been released from the crippled reactors, as well as further radiation that might escape into the atmosphere "could by no means be released to the public," says the document, according to Kyodo News. Yukio Edano, the chief cabinet secretary, told the investigation that he feared, "If that happens, then Tokyo will be finished." The ministry decided that the SPEEDI data should not be released but that "more general" information could be prepared for the public. The ministry declined to comment on the report. The latest revelations are likely to increase distrust in the Japanese authorities as the nation prepares to mark the one-year anniversary of the March 11 disaster. Yoshihiko Noda, the Japanese prime minister, said at the weekend that no individual should shoulder the blame for the crisis at the Fukushima nuclear plant, but that everyone in Japan has to "share the pain" and learn from the disaster.
