Urugi Onsen Komadori no Yu is located in Urigimura, Nagano Prefecture. Its bicarbonate water surfaces at 40°C, shared across an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — In the tiny mountain village of Urigimura, one of Japan's smallest municipalities hidden in the southern Nagano highlands where the Japanese robin (komadori) sings in the cedar forests, Komadori no Yu offers a rare off-grid mountain onsen experience; the village's artisanal wooden crafts, buckwheat traditions, and near-total absence of commercial tourism make this a genuinely undiscovered rural gem.
