Ginzan Onsen is a historic hot spring town located in the mountains of Obanazawa City, Yamagata Prefecture.

The name originates from Nobesawa Silver Mine, which flourished during the early Edo period, giving the area a history rooted in silver mining.

After the decline of the silver mine, the area was developed into a hot spring resort.

In 1913 (Taishō 2), a major flood devastated the town, but reconstruction efforts led to the creation of the multi-story wooden ryokan (traditional inns) with Western architectural influences, which remain today and date back to the late Taishō to early Shōwa periods.

Lining both sides of the Ginzan River are 3- to 4-story wooden inns, and in the evening, gas lamps softly illuminate the streets, evoking the romantic atmosphere of early 20th-century Japan.

Along the walking paths of the town, visitors can enjoy facilities such as the public bath "Shirogane-yu" and the footbath "Waraku Ashiyu", making for a relaxing and nostalgic experience.
