FacilitySpringSource dataSupplyBath type
Ganiba Onsen, Nyuto OnsenkyoBoth are classified by the inn as simple sulfur springs. Source: Ganiba Iō and Karako springs.Source temperature: 54°C at Ganiba Iō and 55°C at Karako.
pH: Not published.		The inn states that its baths use 100% source-flowing water. The wooden and rock baths and the Hinazakura women's outdoor bath use Ganiba Iō; the mixed Karako outdoor bath uses Karako. These sources are kept distinct.Day-use bath. A year-round choice at the end of the Nyuto bus route, with source-flowing baths and a forest-side outdoor bath. It is a poor fit if you need an elevator, card payments or a private bath.
Tsurunoyu Onsen, Nyuto OnsenkyoThe inn uses separate classifications for its four springs: Shiro-yu is a sulfur-bearing sodium-calcium chloride–bicarbonate spring (hydrogen sulfide type); Taki-no-yu is a sulfur-bearing sodium chloride–bicarbonate spring; Kuro-yu is a sodium chloride–bicarbonate spring; and Naka-no-yu is described by the inn as a bicarbonate, salt and hydrogen-sulfide spring. Source: Shiro-yu, Kuro-yu, Naka-no-yu and Taki-no-yu.Source temperature: Current fixed temperatures for the four individual springs are not listed together on the main pages.
pH: Not published in the current review.		The inn identifies four springs with different compositions and indicates which baths use them; for example, the mixed outdoor bath uses Shiro-yu. The current readable pages do not fully publish each bath's water addition, heating, circulation or disinfection conditions, so those details are not generalized across the property.Day-use bath. The signature first stop for a historic, remote hot-spring setting and several distinct springs. Its large outdoor bath is communal, not a private bath, and the location is less convenient without a car.
Taenoyu, Nyuto OnsenkyoGin-no-yu is a simple spring; Kin-no-yu is a magnesium-calcium sulfate spring. Source: Gin-no-yu and Kin-no-yu.Source temperature: Not published in a current fixed figure.
pH: Not published in the current review.		The inn says both of its naturally emerging springs are still used source-flowing in eight baths. Some baths may be unavailable in winter.Day-use bath. A particularly complete option if you want two springs, separate-gender outdoor baths, a mixed bath and a bookable private bath at one inn. It is not the cheapest choice for a quick soak.
