Overview and History of Nyuto Onsen
What is Nyuto Onsen?
Nyuto Onsen (nyutouonsenkyou) is a collective term for hot spring areas in Tazawako, Senboku City, Akita Prefecture. Located at the foot of Nyuto Mountain (elevation 1,478 meters) within Towada Hachimantai National Park, seven hot spring inns are scattered across an elevation range of 600-800 meters. The entire hot spring resort is surrounded by a pristine beech forest, with untouched natural environment being a major characteristic.
A Hot Spring Resort Boasting Over 350 Years of History
Nyuto Onsen has ancient origins, having been used as a hot spring therapeutic facility since the Edo period over 350 years ago. Most notably, Tsuru no Yu Onsen, the oldest hot spring, thrived as a bathing place for Akita domain lords and still retains thatched-roof buildings from that era that captivate visitors.
