Japanese investigator says lessons of Fukushima disaster ignored
In the first of a two-part report, a Japanese investigator warns that the lessons of the Fukushima atomic disaster have been ignored

It was the biggest earthquake to shake Japan. With a magnitude of 9.0, the undersea tremor that rumbled to life on March 11, 2011 shifted the country's main island by more than two metres and unleashed a tsunami that triggered meltdowns in three reactors at the Fukushima Daiichi nuclear power plant. The disaster killed more than 15,880 people and altered forever the lives of hundreds of thousands of families. It also triggered a nuclear crisis that independent investigators have concluded was man-made.

Japan's government, these critics say, has not dealt with problems raised by an independent investigatory commission. Policies are toothless. The nuclear industry hasn't addressed its role in the disaster.
And while the parliament commissioned the investigation, it has failed to follow up. The report blasts a government culture that is averse to taking risks; a crisis-management system that needs a stronger chain of command; powerful nuclear operators that are still not effectively regulated by the government; and nuclear-energy laws that fail to meet global standards.
Why are the Japanese not angry at the restarting of those things?
"At this time, all the investigations have to be international, independent, and all the processes open and transparent. Otherwise you cannot retain the trust," says Dr Kiyoshi Kurokawa, a physician who was chairman of the nine-member Japan Fukushima Nuclear Accident Independent Investigation Commission. It delivered its report in July 2012.
It was the first independent public investigatory commission in Japan's history, and Kurokawa had hoped it would make a difference in a culture that tends not to reflect on past mistakes. Kurokawa and his colleagues urged parliament to investigate further, but he says that advice wasn't taken, and that Tepco never acknowledged the report's findings.
