According to NHK Broadcasting, at 1:9 am on the 25th, the eruption in the southern mountain of Sakurajima reached a place about 1.8 km in the southwest direction.
Fire rush is when hot eruptions such as lava flow down the slopes of a volcano.
On this day, the smoke from the eruption soared up to 2,300m in the sky, but no human damage was confirmed.
Sakurajima Island has been designated as an area that cannot be accessed from the crater to the extent of 2 km since February 2016.
The Japan Meteorological Agency has maintained the level of boundary level around the crater at Level 3, which corresponds to the entry regulation, and warned that there is a possibility that pyroclastic flows could reach a distance of 2.4 km from an additional eruption.
NHK said that about 90 people live in the 3km area closest to the crater, and about 500 people live in the 4km area.
In Sakurajima, the previous occurrence of pyrotechnic flow was in June 2018, and at that time it flowed to a range of about 1.3 km.
