A single inn nestled quietly on the shores of Oosako Dam Lake deep in the mountains, popular with hot spring enthusiasts across the country. The distinctive bath with its rich golden turbid water and travertine formations enveloping the inn are notable features.

The spring has been open since the Heian period and thrived as a hot spring destination in the early Edo period. When Oosako Dam was completed in 1973, the area was submerged, but the source was relocated by excavating 150 meters down into the Hato Valley and reopened the same year. It has continued operating as "Yamahato-yu" since then.

Day-visit bathing is available. Hours are 10:00 AM to 5:00 PM (reception until 4:00 PM). Please contact the inn before your visit.

Sodium bicarbonate and chloride spring water (containing carbonated sodium bicarbonate) rich in iron and calcium. It is a rare carbonated spring found throughout Japan. The water is colorless and transparent but changes to a pale yellowish-brown color after several hours. The bicarbonate content softens old dead skin and it is called "beauty water."

An indoor bath made entirely of cedar logs and a panoramic outdoor bath made from a giant zelkova tree. The outdoor bath offers stunning views of the dam lake and surrounding mountains. The hot spring is self-sourced, naturally flowing at 500 liters per minute.

The hot spring source is colorless and transparent, but when exposed to air, the iron it contains oxidizes and turns a pale yellowish-brown color after several hours. Calcium-based mineral deposits form in the bath, creating a heavy, pottery-like appearance.

Seasonal local dishes including Nancho hot pot, maple leaf hot pot, wild boar hot pot, and duck hot pot made with fresh local river fish, mountain vegetables, and produce prepared in a secret miso sauce. You can also enjoy char and sweetfish rice bowls. Bear hot pot is a specialty in winter.

The parking lot is located near the building entrance (top floor). Because the structure is built along a cliff face, there is a steep staircase down from the parking area to the inn's entrance.
