History
Waga District was under the control of the Nanbu clan of Morioka Domain during the Edo period. The villages of Yuda and Sawauchi were established with the Meiji period establishment of the modern municipalities system on April 1, 1889. Yuda was elevated to town status on August 1, 1964. Nishiwaga was founded on November 1, 2005 from the merger of the town of Yuda and the village of Sawauchi. This merger occurred under pressure from the national government of Japan and in the face of steady but significant depopulating trends in rural Japan in general. The new town's name came as the result of a competition open to entries from all residents of the former Yuda Town and Sawauchi Village, in preparation for the merger. The final decision was made by a vote of representatives from both municipalities. The chosen name, literally "West-Waga Town," reflects the status of the new town as comprising the western portion of Waga District.
Nishiwaga has many natural onsen hot springs. There are several natural hot springs baths operated by the municipality, and inexpensive monthly passes are available to residents. There is also a hot spring heated sand bath at one of the sites. Many traditional bed and breakfast inns operate in these areas, usually with their own private hot spring facilities, some of which are open to day visitors for a fee. The area is also home to rare old-growth beech forests found in few other places in Japan. The Waga River, a major tributary of the Kitakami River and from which the county and current town derive their names, originates high up in the folds of Waga-dake, a peak along the Ou Range which forms the prefectural boundary between Iwate Prefecture and Akita Prefecture. The mountains of Nishiwaga Town have drawn interest from local hikers and outdoors enthusiasts, as well as hikers and ecotourists from as far away as Tokyo. In the southeastern section of Nishiwaga Town the Waga River is restrained by the Yuda Dam, which creates a variable depth man-made lake called Kinshu Lake.
