Easiest route Hiking

Mount Gassan (月山, Gassan) is the highest of the Three Mountains of Dewa in the ancient province of Dewa (modern-day Yamagata prefecture). The Gassan Shrine stands at the mountain's summit, 1,984 metres (6,509 ft) above sea level.


It has a long hike from its trailhead and usually requires about 4-5 hours to hike it. Visitors should be aware of the weather and not try to hike it during windy or days with heavy rain. Also note that the trail is not paved and in some parts requires use of hands to clear certain parts of the trail.

Due to heavy winter snowfall, the mountain and shrine are inaccessible for long periods of the year; however, skiing is possible on the mountain from April to mid-summer.
