A powerful 7.3 magnitude earthquake struck off the coast Japan near the area devastated by a quake and tsunami last year.
FOX News Radio's Alastair Wanklyn reports from Tokyo:
Buildings here swayed violently for a minute or more, office workers gathered round TV sets fearing a repeat of two years ago.
The quake hit in the same area as last time, tsunami sirens sounding on Japan's northeastern coast and residents there fleeing homes for higher ground. Many gathered in sturdy government buildings such as colleges.
It turned out the wave was only small and did no reported damage. But disruption remains here, some railways halted and here in Tokyo it's as evening fell, some commuters seen walking home.
