Japan withheld worst-case scenario of nuclear crisis

The Japanese government’s worst-case scenario at the height of the nuclear crisis last year warned that tens of millions of people, including Tokyo residents, might need to leave their homes, according to a leaked report.

But fearing widespread panic, officials kept the report secret.

The emergence of the 15-page internal document may add to complaints in Japan that the government withheld too much information about the world’s worst nuclear accident since Chernobyl.
