Half of the indoor bathtub floor is covered by river washed stones (both male and female baths). These stones are real stones from the Nishi-river flowing locally in the Sarugakyo area. The stones create a unique texture and massage your feet. Both the hot spring water and the river washed stones will heal your everyday exhaustion. Our rock outdoor bath is located on a stone wall made of massive rocks cut out from the Omine mountain to the east. Please enjoy the hot spring with a view of garden trees.
