Ogawa Onsen

Ogawa Onsen is located in Nakano City, Nagano Prefecture, in the northern Nagano highlands near the Chikuma River, a city known throughout Japan as a leading producer of oyster mushrooms and the gateway to the Shiga Kogen volcanic plateau — one of Japan's largest ski resort complexes and a site of the 1998 Nagano Winter Olympics. The siliceous thermal waters here complement Nakano's position as a comfortable base for exploring both the highland ski and nature tourism of the Shiga Kogen National Park and the apple orchards, sake breweries, and traditional castle town heritage of the Nakano basin. Bathing at Ogawa Onsen connects visitors to the quiet agricultural prosperity of northern Nagano, where the thermal waters provide year-round wellness in a landscape defined by fruit cultivation, mushroom farming, and the spectacular volcanic highlands rising above the Chikuma River plain.
