Some have called it as minor erruption (such as United Press International), but Mount Asama, one of Japan's most active volcanos, spewed ash and smoke up to 2000 metres into the air in an eruption early today.
BBC writes that "Residents living within a 4km radius of the mountain have been urged to be cautious.
"Volcanic ash fell on nearby areas as well as parts of Tokyo, Japan's meteorological agency said.
"TV reports showed neighbourhoods sprinkled with white flakes.
Mount Asama is 2,568m (8,425 ft) high, with snow-covered peaks. No lava flows could be seen."
