Ash clouds are moving northeast and are likely to reach the city of Kanabe in Miyazaki Prefecture.
The volcano has been intermittently active since June 27, 2025.
The Japan Meteorological Agency has maintained the alert level at level and advised residents to avoid approaching a 3-kilometer radius of the crater.
