There are dozens of volcanoes around Japan since the country lies within the "ring of fire".

In fact, the highest mountain in Japan, Mt. Fuji is an inactive volcano.

I'll first start with,

Hokkaido

Mt. Akan
Location: 43.4N, 144.0E
Elevation: 4,916 feet (1,499 m)

Distant view of Akan, a group of stratovolcanoes, that lies within a shallow depression. Me-Akan, the active vent, is the steaming volcano on the left. Some volcanologists think the shallow depression is a caldera.

Mashu
Location: 43.6N, 144.6E
Elevation: 2,805 feet (855 m)

Mashu is a caldera. It has not erupted in historic time. Large eruptions occurred in 4875 B.C. and in 970 A.D. The eruption in 4875 B.C. was from the central vent and produced pyroclastic flows. The eruption in 970 A.D. was the most recent at Mashu. It was from a flank vent.

Rausu
Location: 44.1N, 145.1E
Elevation: 5,445 feet (1,660 m)

Rausu is a Holocene stratovolcano that has not erupted in historic tim

Shiretoko-Iwo-Zan
Location: 44.1N, 145.2E
Elevation: 5,126 feet (1,563 m)

Shiretoko-Iwo-zan is a stratovolcano at the northeast tip of Hokkaido. The basal diameter of the cone is 6 miles (10 km) and a ridge connects to another volcano to the south. There are two craters at the summit. The first confirmed eruption of Shiretoko-Iwo-zan was in 1876. Since then the volcano has erupted at least three times, most recently in 1936. Preceding the 1889 and 1936 eruptions molten sulphur was extruded. All historic eruptions have been phreatic and from vents on the flank of the volcano.

Honshu

Mt. Asama
Location: 36°24?N, 138°31?E
Elevation: 2,568 metres (8,425 ft)

Mount Asama is an active complex volcano in the central Honsh?, the main island of Japan. It stands on the border of Gunma and Nagano prefectures. Standing 2,568 m above sea level, it erupted most recently on September 1, 2004. Previous noteworthy eruptions occurred in 685, 1108, 1783, and 1972; lesser activity has been recorded on dozens of occasions. The eastern slope has a volcano observation station run by Tokyo University.

Mt. Fuji
Location: 35.4N, 138.7E
Elevation: 3,776 m

Mount Fuji is the archetype of the stratovolcano and probably rivals Vesuvius for the best-know volcano. The volcano rises about 3,500 m above the surrounding plain. Fuji has erupted at least 16 times since 781 AD. Most of these eruptions were moderate to moderate-large in size. The most recent eruption was in 1707-1708 from a vent on the southeast side of the cone. The eruption ejected 0.8 cubic km of ash, blocks, and bombs. Five historic eruptions have caused damage, including the 1707-1708 eruption, but no fatalities. Fuji had two large eruption (VEI=5) in 1050 and 930 BC.

It's a dormant volcano to be exact.
