Magnitude 5.4 earthquake shakes Tokyo and surrounds
An earthquake has shaken Japan's capital Tokyo and surrounding areas, injuring several people and causing minor damage.
The quake on Thursday had a 5.4 magnitude and its epicentre was in Chiba prefecture, southeast of Tokyo, according to the Japan Meteorological Agency.
No tsunami warning was issued.
Four people were hurt, including a man who was hit by a falling ceiling light, according to Japan's Kyodo news agency, and some rail service was cancelled or delayed.
Japan is one of the world's most earthquake-prone nations, and a massive 2011 quake and subsequent tsunami killed thousands of people and caused a cataclysmic meltdown at the Fukushima nuclear plant.
