Yugakai hot spring area is surrounded by mountains.
A great time to take a walk is during the autumn foliage season.
Nakamura Inn, founded in 1916 in this old-style hot spring area, is now the only inn still operating.
Thousand Saucers, an accumulation of lime that looks like thousands of plates, around the tub is a must-see.
The spa in this inn contains the highest concentration of metasilicic acid, which makes your skin smooth. Soak in the spa and you will discover your skin becomes moist.
