Gassan

Gassan is a mountain located in the Dewa Mountains of Yamagata Prefecture, Japan. It is one of the three sacred mountains of Dewa, along with Mount Haguro and Mount Yudono. Gassan is the highest of the three, reaching an elevation of 1,984 meters. The mountain is a popular destination for hikers and pilgrims, particularly during the summer months when its slopes are free of snow.

Pilgrims traditionally ascend Gassan to pray for a bountiful harvest and to perform purification rituals. The ascent is often challenging, with steep trails and unpredictable weather conditions.

Gassan is also known for its unique alpine flora and fauna. Its high altitude and remote location have allowed for the survival of rare plant species, some of which are found nowhere else in Japan. The mountain's diverse ecosystem attracts naturalists and botanists.

The climbing season for Gassan typically runs from late April or early May to October, depending on snow conditions. During the winter months, the mountain is covered in deep snow and is generally inaccessible to hikers. Several trails lead to the summit, offering varying degrees of difficulty. The most popular route is the Gassan Trail, which starts from a service road and passes by several shrines.
