Tokyo: Japan's Prime Minister Naoto Kan said Friday's 8.9-magnitude quake caused "major damage" in northeastern Japan, but that nuclear power facilities in the area were not damaged and there was no radiation leakage.

The Prime Minister made this statement during an emergency news conference.

"The earthquake has caused major damage in broad areas in northern Japan," Naoto Kan said, adding, "Some of the nuclear power plants in the region have automatically shut down, but there was no leakage of radioactive materials to the environment."
Kan also said that he has set up an emergency task force to manage the rescue effort.

"The government will make an all-out effort to ensure the safety of all the people and contain the damage to the minimum," Kan said.

The government's top spokesman, Yukio Edano, said the country was sending troops to the quake-hit area to join relief efforts.

Friday's offshore quake triggered a tsunami that hit Japan's eastern coast, sweeping away buildings and cars. TV footage also showed fires burning in the northern city of Sendai. Officials were still trying to assess the extent of destruction.
