TOKYO—Japan broadened the 20-kilometer nuclear evacuation zone around the troubled Fukushima Daiichi nuclear-power plant Monday to include all or part of five towns and villages that housed tens of thousands of people before the disaster, the latest sign that the government was unprepared to grapple with the longer-term implications of its nuclear crisis.
Japanese officials said residents of the affected areas weren't in danger of surpassing government exposure limits anytime soon and said they have about a month to move. But the decision follows criticism at home and abroad that Japanese officials weren't focusing strongly enough on the threat of long-term exposure to low-but-constant levels of radiation.
It also suggests the cleanup is taking longer than expected, as workers battle to keep three of the plant's reactors under control and prevent the further dispersal of radioactive material.
"Japan has been doing drills for possible nuclear accidents, but they assumed that the accidents would be resolved in about 10 days," said Hidehiko Nishiyama, spokesman for Japan's nuclear regulatory agency. "We are now dealing with a crisis of a historic proportion. This has necessitated different kinds of responses than initially planned."
