OTSUCHI, Japan (Reuters) – nearly a week after their home town was annihilated in a catastrophic tsunami, the 1,000-plus survivors of the small Japanese fishing town of Otsuchi are hanging by a thread.

With no water or electricity, and scant food, survivors keep each other company at one of three emergency shelters on the outskirts of what remains of the town. "You can’t wash your hands or face," says 72-year-old Katsu Sawayama, seated in the middle of the high school gymnasium, the biggest of the shelters in a town where more than half the 17,000 residents are still missing.

Adding to their woes, an unseasonal snowstorm sent temperatures plunging to below zero and blanketed acres of tsunami debris in white.

While international attention has been focused on Japan’s efforts to stop damage at a quake-hit nuclear power plant from spiraling out of control, a massive salvage and rescue operation has slowly been gathering steam.

Scores of villages, hamlets and towns lining Japan’s northeast coast were flattened by tsunami waves that rolled in minutes after Friday’s 9.0 magnitude earthquake.

While the official toll stands at less than 5,000, thousands more are listed as missing and the final tally is likely to soar.

About 850,000 households in the north were still without electricity in near-freezing weather, Tohuku Electric Power co. said, while the government said at least 1.5 million households lacked running water.

Like tens of thousands of people along Japan’s northeast coast, the Otsuchi survivors have nowhere else to go. Meals are barely enough to sustain them — half a rice ball and a small bowl of miso soup is a luxury; a slice of bread might have to feed a family of three.

"whatever they give us, we just gratefully receive. At least they’re feeding us three times a day," said Sayawama.

International experts say that panic over fears of radiation leaks from the Daiichi nuclear plant could detract from problems likely to affect survivors of the quake and tsunami, such as the cold, access to clean water and getting enough food.

"People are getting so concerned about what are at the moment pretty low levels of radiation," said Dr. Richard Wakeford of Britain’s University of Manchester, "but the real problems … are in dealing with the earthquake and the tsunami."

"if this was a developing country, we’d have people going down in their hundreds and thousands with the likes of typhoid and cholera by now. the questions should be: Where is the sewage going? What is the state of the drinking water? if I were a public health official, that would be my principal concern."

Ayumi Yamazaki, 21, is already concerned and worries her 1-1/2-year-old daughter is not getting enough to eat.

"we rarely get to eat rice, so I’m a little concerned," she said, "but it’s better than not eating at all."

Math teacher, Naoshi Moriya, volunteering at the evacuation site’s make-shift logistics office, says he’s worried that it is only a matter of time before food runs out.

Despite the privations there’s a sense of order in the evacuation center. in late afternoon, a neat queue forms in one hallway of the refuge shelter for men under 60 years old to collect clean undergarments sent in through charity. "Long-sleeve undergarments are reserved for the elderly," a volunteer who lost her home says, apologizing to one man.

Outside help is slowly and sparingly arriving. a Self-Defense Forces truck carrying a fresh supply of water arrived late afternoon on Wednesday, and two Red Cross teams arrived for the first time to treat patients.

"It’s cold today so many people have fallen ill, getting diarrhea and other symptoms," said Takanori Watanabe, a Red Cross doctor from Himeji, western Japan. he says 80 people queued up when they arrived.

Elsewhere there were signs of human touches.
