Introduction of the Accommodation

Enjoy the open-air bath with seasonal scenery, featuring smooth and silky water for beauty.
The Mizubasho Onsen, abundant in natural spring water. The silky smooth water is a colorless, transparent, mildly alkaline simple hot spring. After a relaxing soak, it is reputed to leave your skin moist and radiant, earning the title of 'beauty-enhancing water.' It is also said to warm the body thoroughly and prevent post-bath chills.

The mountain's underground water (Onsen) contains numerous nutrients. Nutrients from trees, flowers, forests, and lakes are carried by rain, eventually flowing underground where the water is heated, forming an Onsen.

Himebashou Hot Spring
The indoor bath, renowned as "Hot Water Beauty," is praised for its effects. During bathing, the water glides smoothly over the skin, and after bathing, it leaves the skin moisturized. Open 24 hours (gender-specific alternating schedule).

Mizubashou Hot Spring
A colorless, transparent, mildly alkaline simple Onsen (alkaline hypotonic Onsen). The abundant water flow of 55 liters per minute is attractive. Open for bathing 24 hours (gender rotation system).

"Tadaima" "Okaerinasai" Experience a relaxing moment in a Japanese-style room that exudes a harmonious atmosphere.

The seasonal delicacies, treasures nurtured by Oze's spring water, enhance the flavors and colors of Umedaya's cuisine.
