One of Dewa Sanzan, sacred peak in Yamagata with alpine marshes.
Mt. Gassan (1,984m) is one of the Three Sacred Mountains of Dewa (Dewa Sanzan) in Yamagata Prefecture, revered in Shugendo mountain worship for over 1,400 years. The gentle, grassy summit plateau is blanketed with alpine wildflowers in summer, including the rare gassan-furo geranium. Deep snow covers the mountain well into summer, providing Japan's latest skiing season alongside ancient pilgrimage trails.
