“Senbata Onsen Sun R” is a hot spring accommodation facility located at the foot of the Ōu Mountain Range in Misato Town, Akita Prefecture. From the large bath, which is lined with glass on all sides, you can take in a sweeping panorama of magnificent nature that changes with the seasons. The sauna room is a dry sauna with steady heat that feels comfortable, and the background music flowing through the quiet, TV-free space invites deep relaxation. In March 2024, a much-anticipated cold plunge bath was newly added, and its crisp chill instantly tightens up your body after sauna use. You can also enjoy outdoor air bathing in the open-air bath, where you can feel the refreshing air of Ōu and savor a blissful totonou experience.
