Yahiko Shrine — Sacred Mountain Vermillion Gateway

Yahiko Shrine sits at the base of Mt. Yahiko (634m), a sacred peak that has been a Shinto pilgrimage site for over 2,400 years. The shrine venerates Amenokagoyama-no-Mikoto, a deity of agriculture, fishing, and salt-making who, according to the Kojiki (Japan's oldest chronicle), taught early Japanese people rice cultivation techniques. The shrine's main hall, rebuilt in 1916 after a fire, features distinctive vermillion pillars and copper roofing that has aged to pale green.

The approach to the shrine passes through a 1,000-meter cedar forest with trees over 400 years old, creating a cathedral-like atmosphere. The shrine grounds include a treasure hall displaying Heian-period (794–1185) swords and mirrors designated as Important Cultural Properties. A ropeway behind the shrine ascends Mt. Yahiko's summit in 5 minutes, offering panoramic views of the Echigo Plain and Sea of Japan.
