Three Sacred Peaks

Located in the centre of Yamagata Prefecture, the Dewa Sanzan is the collective name for three sacred mountains, Haguro-san, Gassan, and Yudono-san, revered for their spiritual prowess since ancient times.

Trip Through Time

Haguro-san represents the world of the present and the salvation of current hardships. Gassan represents the past or the afterlife where we atone for our wrongdoings. Lastly, Yudono-san embodies the world of the future and marks the location we are reborn.

Spiritual Awakening

Gassan is where the souls of the ancestors venture after they pass on to the other world. As such, we are able to physically be one with those who have gone before us as we pay our respects. At the same time, Buddha’s mantras are projected onto the Dewa Sanzan. Thus, navigating the mountains is to embody their wisdom.
