Day Use
YesClosures follow an irregular schedule rather than a fixed weekly day off. The bath stays open through New Year's and Golden Week; check the official calendar for specific closed dates.
Prices rise to 900 yen for adults and 450 yen for children (normally 400 yen) on peak days: Golden Week, Obon, New Year, and long weekends. A 6-visit ticket book costs 4,000 yen (4,500 yen on peak days). Spend 500 yen or more at the on-site restaurant, Oni no Kuriya (鬼の厨), and the bath is half price.

Highlights
Lukewarm BathAbout
This day-use bath sits inside the Michi-no-eki Otari roadside station, in a mountain valley in northern Nagano. The water blends two local springs and comes out with a faint brown tint and a light metallic edge, locally said to be good for the skin. Indoors there's a hot bath with a lie-down section, a cooler bath meant for kids or a slower soak, a cold plunge, and a dry sauna; outside, an open-air bath lets you watch snow fall in winter or catch the color of the maples in autumn. A restaurant next door serves local Otari food, and there's a tatami hall and courtyard to rest in after the bath.
