Sakurajima, one of Japan’s most active volcanoes, erupted on Sunday in the country’s southwest, the Japan Meteorological Agency said, warning of possible ashfall.
The eruption sent a plume of ash and smoke up to 4,400 m into the sky, the agency said, according to AFP.
Authorities urged residents to take precautions against falling ash, including using umbrellas or masks, and advised drivers to reduce speed.
The alert level remains at three on a five-point scale, restricting access to the mountain.
