Mount Aso is the largest active volcano in Japan.
Located in Aso Kuju National Park in Kumamoto Prefecture, on the island of Kyushu, Mt. Aso has a fairly large caldera with a circumference of around 120km.
The crater of Mt. Naka, accessible by road on the west side, contains an active volcano which continuously emits smoke and has occasional eruptions.
