"It is important that each of us shares the difficult days that lie ahead," said Akihito, 77, a figure who keeps a low profile but is deeply respected across the country. "I pray that we will all take care of each other and overcome this tragedy."

He also expressed his worries over the nuclear crisis, saying: "With the help of those involved I hope things will not get worse."

The emperor, who has been on Japan's throne for the past 20 years, thanked those involved in disaster relief operations, including foreign governments, and urged an all-out rescue effort.

"We don't know the number of victims, but I pray that every single person can be saved," he said.
