We regret to inform you that we do not accept guests with children in elementary school or younger. We appreciate your understanding and cooperation.

This facility is located within a national park. The collection and removal of all plants, animals, minerals, and other items from the park, and the bringing of such items into this area, are strictly prohibited. Your cooperation in environmental conservation and maintenance is appreciated.

We are open year-round for overnight stays. The Shiraobone Hot Spring Line is passable throughout the year, so access is available in winter as well. However, day-use bathing may close temporarily due to severe winter weather. Please call ahead to confirm.

A mixed-gender large outdoor bath where you can enjoy the milky-white waters of Shirahone Onsen. You can take in seasonal scenery throughout the year—cherry blossoms in spring, fresh greenery in summer, autumn foliage in fall, and snow-viewing in winter. Because the water is milky-white, the interior of the bath cannot be seen, making it comfortable for couples and groups.

Guests wear thick bath towels while bathing. Additionally, there is a dedicated women's changing room with direct access to the bath, allowing guests to enter the co-ed Ohno open-air bath while already in the water, so you can use it with peace of mind.

We offer day-use bathing. However, we may close unexpectedly due to boiler fuel issues, bad weather, or scheduled closures. Please call us on the day (0263-93-2101) to confirm availability.

We won 1st place in Nagano Prefecture in the Rakuten Travel Breakfast Festival 2019. We also received 3rd place nationally in 2018. Please enjoy our breakfast featuring local ingredients.
