A hot spring district located halfway up the Zao Mountain Range. The oldest hot spring district in Yamagata Prefecture, the area's history as a hot spring bath center stretches back over 1,000 years. One of the area's greatest charms is its seasonally changing scenery, from fresh verdure in the spring and summer to fall foliage in autumn to snowscapes and frost covered trees in winter. There are five hot spring clusters in the area and over 40 source springs, and the district has been designated a National Hot Spring Health Resorts. There are strongly acidic springs in the area, a rarity in Japan, as well as sulfur springs, and the milky white waters of the district, which soak into the skin with a tingling sensation, are said to be very effective at beautifying the skin, making this a renowned destination for those seeking lovely, smooth skin. There are three public baths in the district, and visitors can enjoy stopping by each to bath, compare, and pick their favorite.
