(TOKYO) -- The international and domestic terminals at Narita International Airport were crammed with passengers leaving the capital after a small spike in radiation levels was detected in Tokyo. The spike followed a reactor fire that has raged for two days at a troubled nuclear plant 150 miles north of the city; four of the plant's six reactors were damaged in last Friday's earthquake. People living in a 30 kilometer radius of the plant were evacuated, but those further away are no less nervous.
Germany's Lufthansa airline became the first major carrier to cancel flights to Narita and will reroute all flights through Nagoya and Osaka, some 300 miles south of the capitol. Dutch carrier KLM followed.
While the United States and Britain told their citizens to avoid non-essential travel to Tokyo, France told its citizens to evacuate the city, a markedly different instruction than from the Japanese government's urging residents to remain calm.
Korean Airlines arranged special charter flights out of Narita to whisk Koreans out. The carrier even offered discounted one-way tickets, with priority going to Koreans living in Japan who are likely to be affected by the explosion.
"It was a spur of the moment decision," said Adam Lobel, an American expatriate who has lived in Japan for 11 years but decided to fly to New York Wednesday.
"It is a heart-wrenching decision, but the situation does not appear good," he said while standing in line with his wife to check in at Narita airport.
Lobel said he would "assess the situation" and planned to return next week if things had become more settled.
Lobel said he arrived at the airport five hours early anticipating long lines.
Many of the city's international schools closed for two weeks in the wake of the earthquake and many of the people leaving from Narita were families with young children.
Julia Chang brought her 11-year-old daughter, who is a student at one of the city's international schools, to the airport today frantically looking for a flight out of Japan to either Korea or China.
"I just want to make sure my daughter is safe. Everything's so confusing and we don't know who to believe. I'm not taking chances with my girl," Chang said.
Chang was able to book a flight only for her daughter to leave on Friday to Seoul, South Korea, where she can stay with her grandmother.
Those who can't leave the country or are keeping their options open are moving further south to Osaka.
Emperor Akihito, the country's revered 77-year-old monarch, did little to reassure the country in a rare public address, saying: "With the help of those involved I hope things will not get worse."
