Okuyamada Onsen is a small hot spring area in Takayama Village, Nagano Prefecture, set high in the mountains above the better-known settlements of the Matsukawa Valley. The setting is the main draw: forested slopes, open skies, and a sense of distance from the busier resort towns found elsewhere in the region.
Rather than a lively onsen town, Okuyamada Onsen feels quiet and self-contained, the kind of place people choose for a slower stay and easy access to the surrounding highland landscape. It also sits within reach of the wider mountain areas of northern Nagano, making it a natural base for travelers who prefer their hot spring stops simple, rural, and close to nature.
