A magnitude-8.5 earthquake struck off the Ogasawara Islands south of Tokyo on Saturday evening, jolting wide parts of the Kanto region and causing moderate tremors in many parts of the archipelago, the Meteorological Agency said.
No tsunami warning was issued by the agency, and no serious injuries or major damage were immediately reported in the Ogasawara chain by local authorities.
In Kawaguchi, Saitama Prefecture, a woman in her 70s sustained a minor injury when dishes fell on top of her head at home. In Minato Ward, Tokyo, a building elevator stopped suddenly, trapping people inside.
