It is really that bad.
If the U.S. Nuclear Regulatory Commission or the International Atomic Energy Commission had any sense, they would immediately hire a team of Japan scholars to tear this [unfortunate choice of words removed - Ed.] apart, and form special investigative commissions of their own to compare and contrast all the official reports produced so far.
The download page of the Kurokawa Commission report crashed a little after 9 pm last night (and is still down at the time of the publication of this post), preventing access to the most important versions of the documents. The reports themselves, when one could access them, were presented in impossible to copy-and-paste formats and in a maze of links and pages, indicating how little the powers-that-be have wanted the world and/or the citizens of Japan to take look at the Commission's findings and come to their own conclusions.
That the English language version of the report has the commission president blaming Japanese culture for contributing the disaster, whilst the Japanese language version omits this little chestnut, is simply so revolting an appeal to international stereotypes regarding the people of this blessed land that my morning coffee today tastes like sewer water -- and Amaterasu knows I love my coffee.
