They're scared. And they're skeptical.

The government in Tokyo may be reassuring a nation already reeling from the worst earthquake in its recorded history that Japan is not about to experience a full-blown nuclear disaster.

But the closer you got to the Fukushima nuclear complex, where officials are struggling with the specter of meltdowns at two of its six reactors, the less people were buying it.

On National Road 4 on the city's outskirts, Mari Kano was crawling through congested traffic Sunday morning with her two young children in tow, baskets of clothes and toys in the back of her station wagon.

"I'm extremely worried about this nuclear leakage, especially with children," the 33-year old homemaker said. "We live 12 miles from the reactors. We've left our home to stay with my parents. At this point, we have no idea how long it might be before it will be safe to return."

The Japanese have an uncomfortable relationship with nuclear power. The country relies heavily on nuclear energy for electricity; with 55 plants, they have more than any country other than the United States and France. But Japan is also the only country to ever be the victim of an atomic attack, and the psychological weight of the bombings of Hiroshima and Nagasaki adds a sense of dread to the embrace of nuclear power.

Outside Fukushima, a Super Viva housewares store was mobbed by people buying up flashlights, batteries, water and pumps. They feared aftershocks, but they also feared disaster at the nuclear complex.

"I'm so scared," Kin Anzawa, 75, said, bent to the waist and looking to buy tape "to keep things from falling."

"There's nobody to help us."

And many did not trust the authorities were telling them everything they know.

An electrician struggling against the tide of fleeing residents to get to Fukushima to work on various power-related problems said he had his doubts.

"We need them to be more honest," said Kuni, 43, who declined to give his first name. "They may be telling the truth. They may not. We really don't know."

Ken Sasaki, 40, a construction ministry official manning a roadblock, said the images on television of the reactor building's top blown off didn't engender great confidence.

"Personally, nuclear power makes me a bit nervous," he said. "But as a nation, I still think we need it."

Since Friday's devastating quake, Tokyo Electric Power Co., which operates the Fukushima facility, has been trying to prevent meltdowns at the complex. The government has issued evacuation orders for a 12-mile zone around the complex, affecting an estimated 180,000 people.

As many people here are well aware, the company, known as Tepco, has a history of not being forthcoming about nuclear safety issues, particularly those surrounding earthquake-related dangers. In 2003, all 17 of its nuclear plants were shut down temporarily after a scandal over falsified safety-inspection reports. It ran into trouble again in 2006, when it emerged that coolant-water data at two plants had been falsified in the 1980s.

Critics have long expressed deep concern about safety at many of Japan's nuclear facilities, some which date back to the 1970s and 1980s. Fukushima has long been on critics' radar, but so has the Hamaoka plant, just 100 miles southwest of Tokyo, which perches on an active fault line.

"I have been warning about Japan's possibility of a genpatsu shinsai — a nuclear disaster," said Katsuhiko Ishibashi, a seismologist and professor emeritus at Kobe University. He said Fukushima was only one of a number of nuclear complexes in seismically unsafe locations.
