  • This was my first time staying here.

    This was my first time staying at Shirahone Onsen.Given the staffing shortage, I think it would be helpful to more actively introduce systems that encourage self-service—for example, placing call bells and water in the dining area. In many situations, a brief note or explanation would make things clear. The Onsen atmosphere was excellent, just as reputed.

  • I can’t wait to soak in that bath again.

    This was my first return in eight years.I had been hoping to visit that bath again someday, and chose this Accommodation because it is close to the Shin-Hotaka Ropeway, our destination.The amazake and oyaki served at check-in were delicious. I wanted to buy some to take home, but they said they are not for sale, which was very disappointing. (I also couldn’t find them at the roadside station they recommended.)Compared with before, the dining area has been updated with tables and chairs, and the meals also felt upgraded. The attendants were all Japanese and provided courteous service. The open-air bath is now by reservation, so it was nice not having to go check for availability.To reach Zaboan and the baths, you need to climb a long staircase, which may be difficult for guests with mobility issues. I recommend staying at Zaboan while you are still able-bodied.Since this is a standalone house-style Accommodation, it would be nice if there were a vending machine on site.

This renowned Onsen, known for its gentle sulfur aroma and milky white hues, is said to have the remarkable effect of preventing colds for three years after just three days of bathing. The only free private open-air bath in Shirahone Onsen offers a luxurious experience surrounded by the beautiful birch forest that changes with each season. In the semi-open-air bath, you can soak in a naturally artistic tub formed by crystallized spring components while enjoying a tranquil bathing experience and drinking the Onsen water.

Notice from the Accommodation

  • [Important] Important Notice Regarding Your Accommodation Reservation

    Thank you very much for your continued patronage of Shirahone Onsen Konashi-no-Yu Sasaya.

    We would like to inform you that, in response to many requests from our guests, we plan to transition—around next year—to an Accommodation exclusively for adult guests.

    Accordingly, we will no longer accept new Reservations for stays accompanied by children (elementary school age and under).

    To guests who have stayed with children in the past, we sincerely apologize and express our heartfelt gratitude for your support.

    For guests who already have Reservations with children, please rest assured that we will welcome you as always with sincere hospitality.
    We kindly ask for your continued support of Konashi-no-Yu Sasaya as we move forward with this change.

    Please note that while new Reservations accompanied by children are no longer accepted, until the transition is fully completed there may still be occasions when families with children are staying at our Accommodation. Thank you for your understanding.


    Konashi-no-Yu Sasaya

  • Escape to a cool retreat on hot days.

    How is everyone doing?

    In the coming season, many hot days are expected.

    Shirahone Onsen, where our property is located, sits at an elevation of about 1,400 m and is said to be around 6–8°C cooler than Matsumoto City (about 600 m).

    It feels especially cool in the shade, and in our guest rooms you can stay comfortable with just a fan.

    Why not soothe your everyday fatigue with high-quality Onsen waters and a pleasant summer retreat?
