Easiest routeHiking

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.

The mountain is interesting in that it contains elements of both shield volcanoes as well as stratovolcanoes, although it is classified as a stratovolcano.[2]
