Mount Gassan

Mount Gassan is a stratovolcano in the ancient province of Dewa and the highest of the Three Mountains of Dewa. The Gassan Shrine stands at the mountain's summit, above sea level.
The hike from its trailhead to the summit usually requires about 4-5 hours and can be challenging. Visitors should be aware of the weather and not try to hike it on days with wind or heavy rain. The trail is not paved and in some parts requires the use of hands to navigate certain parts of the trail.
Due to heavy winter snowfall, the mountain and shrine are inaccessible for long periods of the year; however, this also means that skiing is possible on the mountain from April to mid-summer.
The mountain is interesting in that it contains elements of both shield volcanoes as well as stratovolcanoes, although it is classified as a stratovolcano.
