The Japanese government upped the danger rating
for the disaster at the Fukushima Daiichi Nuclear Power Station to its highest
level, 7, on Tuesday, a month after an earthquake and tsunami devastated the
country. It was not yet clear whether the administration or the Tokyo Electric
Power Company, which runs the plant, withheld the extent of the risk. But the
local media's habitual allegiance to officials who arrange press conferences
and companies that buy advertising makes it hard to tell, and freelancers who
are eager to probe deeper say their questions have been suppressed.
