Yuda Onsenkyo Sugo Onsen (Toge no Yu) is a hot spring facility in Nishiwaga, Iwate Prefecture, positioned at a mountain pass. The sodium-chloride water flows at 42°C, pH 7.3. An indoor bath, an outdoor rotenburo bath and a sauna complete the offering.
Insider tip — Toge no Yu, the mountain pass spring, marks the high point of the Yuda Onsenkyo spa corridor in Nishiwaga where multiple resort inns cluster around shared geothermal sources. The Sugo area spring is prized for its slightly stronger mineral content that builds up on the skin with a perceptible silky coating after soaking.
