Despite the great need and growing death toll, many search and rescue dog teams from around the world are being delayed from getting to the Japan's quake zone by the country's stringent customs regulations on importing animals.
"There are many rules here. So it's taking a long time," a member of the Swiss team told ABC News.com in the customs area of Narita International Airport, moments after an aftershock rolled through the airport.
U.S. officials said they are working with Japanese to expedite approval of dog teams.
