Some 390,000 people, including many among Japan's aging population, are homeless and battling near-freezing temperatures in shelters in northeastern coastal areas.
Food, water, medicine and heating fuel are in short supply.
"Everything is gone, including money," said Tsukasa Sato, a 74-year-old barber with a heart condition, as he warmed his hands in front of a stove at a shelter for the homeless.
Health officials and the UN atomic watchdog have said radiation levels in the capital Tokyo were not harmful. But the city has seen an exodus of tourists, expatriates and many Japanese, who fear a blast of radioactive material.
"I'm leaving because my parents are terrified. I personally think this will turn out to be the biggest paper tiger the world has ever seen," said Luke Ridley, 23, from London as he sat at Narita international airport using his laptop.
"I'll probably come back in about a month."
Though there has been alarm around the world, experts have been warning there is little risk of radiation at dangerous levels spreading to other nations.
The U.S. government said "minuscule" amounts of radiation were detected in California consistent with a release from Japan's damaged facility, but there were no levels of concern.
Amid their distress, Japanese were proud of the 279 nuclear plant workers toiling in the wreckage, wearing masks, goggles and protective suits sealed by duct tape.
"My eyes well with tears at the thought of the work they are doing," Kazuya Aoki, a safety official at Japan's Nuclear and Industrial Safety Agency, told Reuters.
G7 INTERVENTION FOR YEN
The Group of Seven rich nations succeeded in calming global financial markets in rare concerted intervention to restrain a soaring yen.
The dollar surged to 81.98 yen JPY on Friday after the G7 moved to pour billions into markets buying dollars, euros and pounds — the first such joint intervention since the group came to the aid of the newly launched euro in 2000.
The dollar later dropped back to under 81 yen, but it was still far from the record low of 76.25 yen hit on Thursday.
"The only type of intervention that actually works is co-ordinated intervention, and it shows the solidarity of all central banks in terms of the severity of the situation in Japan," said Kathy Lien, director of currency research at GFT in New York.
Japan's Nikkei share index .N225 ended up 2.7 per cent, recouping some of the week's stinging losses. It lost 10.2 per cent for the week, wiping $350 billion off market capitalisation.
The plight of the homeless worsened following a cold snap that brought heavy snow to the worst-affected areas.
Nearly 290,000 households in the north were still without electricity, officials said, and the government said about 940,000 households lacked running water.
Aid groups say most victims are getting help, but there are pockets of acute suffering.
"We've seen children suffering with the cold, and lacking really basic items like food and clean water," Stephen McDonald of Save the Children said in a statement on Friday. |
