- The latest report comes from a government-formed panel of investigators
- It follows a scathing parliamentary report that described a "man-made disaster"
- The report Monday criticizes the plant operator's lack of preparedness
Tokyo (CNN) -- A Japanese government report Monday heaped fresh criticism on the operator of the nuclear power plant where a disastrous accident was set off last year by the devastating earthquake and tsunami that hit the country.
The measures taken by Tokyo Electric Power Co. (TEPCO), the plant operator, and the Japanese nuclear regulator to prepare for disasters were "insufficient," the report said, and the response to the crisis was "inadequate."
Even now, more than one year after the disaster, TEPCO doesn't seem to be making much effort to clearly investigate the causes of the accident at the Fukushima Daiichi plant, the report's authors said.
The report by a government-formed panel of investigators was the fourth and final one on the nuclear disaster. It comes at a time of growing anti-nuclear protests in Japan.
The fight for nuclear energy in Japan It follows a damning parliamentary report earlier this month that said the crisis was a "man-made disaster" resulting from collusion between TEPCO, regulators and the government. That report said the disaster should have been predicted and prepared for.
How to prevent another Fukushima disaster A February report by independent scholars and journalists also concluded the plant operator could and should have done more.
Only TEPCO's own internal report in May said no one could have predicted the scale of the earthquake or the devastating tsunami that followed. However, it did admit it was not fully prepared and acknowledged criticism it took too long to disclose information.
