A U.S. warship will take part in next week's Tokyo Metropolitan Government earthquake drill with a scenario that millions of people need to be taken to safe areas, metro officials said Friday.

The navy will be joining the Maritime Self-Defense Force and the Japan Coast Guard in transporting people during the exercise. It is the first time for the U.S. Navy to participate in a drill held by the metro government.

The Sept. 1 drill assumes that a quake measuring 6 on the Japanese intensity scale to 7 -- a violent earthquake -- has occurred in Tokyo Bay, leaving 4,300 people dead, 154,000 people injured and 4.47 million people stranded.
