Hirayu Onsen, Onsen in Takayama City, Gifu Prefecture, Japan
Hirayu Onsen is a small mountain village in the Japanese Alps known for its hot springs fed by volcanic activity beneath the ground. The water contains chloride and hydrogen carbonate minerals, and about 30 public and private baths are scattered throughout the village, with many designed as open-air pools that let visitors soak while viewing surrounding peaks.
Hirayu Onsen has a history reaching back hundreds of years, with local legends telling of samurai who found refuge here during Japan's civil wars. Stories describe how they observed a white monkey licking its wounds in a hot spring, which inspired them to do the same, and this helped spread the reputation of the springs.
The name Hirayu Onsen reflects its place in the mountains, where travelers have sought the healing waters for generations. Visitors see this tradition alive today as people carefully rinse before entering the baths and walk through the streets wearing light cotton kimonos called yukata, sampling local dishes like eggs cooked in thermal water.
The village is about one hour by bus from Takayama and offers scenic views of forests and mountains during the journey. Most visitors gain easy access to the baths since no reservations are needed, and you can move between several options to explore different temperatures and settings depending on your preference.
One standout feature is Hirayu no Mori, the area's largest bath with multiple pools nestled among trees creating a peaceful scene, though it can get crowded during busy seasons. Less well-known is the traditional Hirayu no Yu bath, which is smaller and offers a more intimate setting while preserving classic Japanese design.
