A large amount of ash is expected to fall in Aso, Takamori and Minami-Aso in Kumamoto Prefecture.
The agency raised the volcanic alert to Level 2 on its five-level alert scale on Oct. 13 after intensified volcanic activity began to be seen there around 3:30 p.m. the day.
The amplitude of volcanic tremors began to increase at around 2 p.m. Monday.
The agency raised the volcanic alert to Level 3 following the eruption on Wednesday. There were no reports of injuries or damage as of 1:15 p.m. on that day, according to the city of Aso.
Mt. Aso erupted repeatedly in 2016, and volcanic ash fell over a wide area. Volcanic activity continued at the mountain until last year after the No. 1 crater of the Nakadake peak erupted in 2019, affecting tourism and other industries.
