The Japan Meteorological Agency (JMA) recorded the volcano's first eruption during the past five months, after its last eruption in November 2019.
On 28 April at 21:10 local time an explosion generated an ash plume, which reached approx. 6,000 ft (1,828 m) altitude.
The warning bulletin states that ballistic impacts of volcanic bombs and pyroclastic flows could affect an area of about 1 km distance from the main crater.
