Kinugawa Onsen Yudokoro Suzukaze, in Nikko, Tochigi prefecture, stands out for its iron-rich water with a pH of 6.3, at 38°C. An indoor bath, an open-air outdoor bath and a sauna round out the offering.
Insider tip — Kinugawa Onsen Yudokoro Suzukaze is a ryokan bathhouse along the celebrated Kinugawa gorge in Nikko, Tochigi, one of the Kanto region's most scenic onsen valleys. The iron-rich waters emerge with a gentle mineral warmth ideal for long soaks while listening to the river rushing through the dramatic gorge below. Suzukaze means cool breeze, and the open-air bath delivers exactly that sensation above the rushing Kinugawa river. The proximity to Nikko's UNESCO shrines makes this a natural complement to a cultural day out.
