Nyuto Onsenkyo, Akita Prefecture
Tsurunoyu Onsen, Nyuto Onsenkyo
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.

- Spring classification
- The 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.
- pH
- Not published in the current review.
- Flow rate
- Not published in the current review.
- Water handling
- 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.
Bathing indications
The inn describes the four springs by their distinct bathing qualities and traditional names. Terms such as “beauty bath” or “childbirth bath” are not personal health or treatment guarantees.
Day admission is ¥700 for adults and ¥300 for children. The mixed outdoor bath is a shared public bath, not a bookable private bath. Tattoo policy is unconfirmed.
How to read a bath profile
Spring-source temperature and actual bathing temperature are kept separate. Each score is shown independently for comparison rather than collapsed into one overall score.
