Best onsen for Asthma in Fukushima

The Yuhanazawa No.3, No.5 and No.6 Combined Source gathers three springs welling up in the Yuhanazawa district of Takayu Onsen, a spa said to have opened in the Keicho era and once counted among the "Three Takayu of Oshu" alongside Zao and Shirabu. Tart at pH 2.6 and scented with powdery sulfur, its water gushes from the spouts in a blizzard of white mineral flakes, steeping the tubs in a milky blue. It suits travelers seeking a genuine mountain sulfur soak.

Makukawa No.1 Source gushes naturally deep in the folds of the Azuma mountain range, beside the Makukawa stream at around 1,300 meters. Emerging at 54.2°C, the clear water mellows as it travels through the pipes, and its 154 mg/kg of metasilicic acid lends a gentle, moisturizing touch. It suits travelers who wish to unwind slowly in mountain silence.
