Founded in 1868, this Accommodation has built over 240 years of history as a guardian of its hot springs and has now been reborn as a dog-friendly Accommodation. Savor the milky, free-flowing hot spring water from three private sources in the large public bath and open-air bath. Enjoy a relaxing, steam-filled stay with your beloved dog through Japanese-style hospitality experiences such as the courtyard dog run and special ema plaques for dogs.

Our story began when an Onsen sprang forth after we dug at a place seen in a dream. We named it “Yume no Yu” and started with a single small inn—this is the origin of our Accommodation (Oda Onsen). Also enshrined here to this day is the “Ryujin Tree” (dragon-shaped tree roots), which was also seen in that same dream. A small rural farming village has since become a mountain Onsen retreat. Why not come and experience this mysterious Onsen, said to hold an uncanny power?

We take pride in our Onsen, a variety of baths, and handmade cuisine crafted without relying on pre-made products (limited to a set number per day). Guests can enjoy five private baths at no additional charge. All baths feature free-flowing Onsen water. You are welcome to use the hinoki wood family bath or the stone family bath freely. The natural Onsen water is colorless, odorless, and sourced directly from our private spring on-site, flowing continuously (free-flowing source). Notably, Gennoyu and Koshiburo Ichinoyu are supplied directly through natural gravity as they are located lower than the spring source. Please note that as this is a wooden building, there is no elevator; guests will need to use stairs. Meals are served in the dining area. For stays of three nights or more, meals from the third night onward will repeat the menu from the first and second nights. We regret that we cannot accommodate changes to meal content (including allergies or preferences). All rooms and indoor areas are non-smoking, including electronic cigarettes.
