Amidaga Falls, Sacred waterfall in Gujo, Japan

Amidaga Falls is a waterfall in Gujō that drops over a rock face, creating white streams of water. The flow descends along the stone surface, offering different vantage points for viewing.

The waterfall was discovered in 722 by Taichō, the monk who founded the mountain worship of Mount Haku, and was first named Nagataki. During the Tenbun era of the Sengoku period, the monk Dōga of Nagataki-ji performed a goma ritual in a cave nearby, and Amida Nyorai appeared before him; this gave the fall its present name, Amidaga Falls.

The waterfall is the subject of Katsushika Hokusai's woodblock print "Amidaga Falls in the Depths of the Kiso Road" from his series Tour of Waterfalls in Various Provinces. The name comes from a legend that the monk Dōga of Chōryū-ji saw Amida Buddha appear while practicing goma in a cave nearby during the Tenbun era.

From the Mino-Shirotori station of the Nagaragawa Railway, take the Gujo city bus on the Itoshiro line and get off at the Amidagataki stop; the fall is about 20 minutes on foot from there. By car it is roughly 15 km from the Takasu interchange via Route 156 and Prefectural Road 314. Two eateries stand along the walking route beyond the car park.

During July, a festival takes place where people sit under the cold water for cleansing rituals. This old practice shows how the location is still used for spiritual purposes today.
