Mount Akagi is a composite volcano with a caldera
and a few caldera lakes, and is located about 20 km north-northeast of
It is one of the Gunma's three major mountains, along with Mount Haruna and Myogi.
In Japanese, it is called "Akagiyama" or "Akagisan".
In an ancient document, there is a mention that Mount Akagi errupted in
So Japan Meteorological Agency has designated this mountain as an active volcano.
But the sediment by the eruption hasn't been found, therefore, some experts say that this isn't an active volcano.
There is a caldera on the top of the mountain, and there are several
peaks along the somma.
The highest peak is "Kurobisan", and it is 1,828 meters high.
On the bottom of the caldera, there are three caldera lakes. The largest lake is "Oonuma", and the others are "Kakumanbuchi" and "Konuma".
This mountain is a volcano, but it has no current active volcanic vent
So there are a visitor center and ski slopes in the caldera, and Akagi shrine is near Lake Oonuma.
Some roads lead to the bottom of caldera, so we can visit there by bus or car.
