Poroto Onsen is a small, traditional hot spring located southwest of Lake Poroto in Shiraoi, Hokkaido. Known for its skin-softening waters, this onsen offers a unique bathing experience with its brownish, mineral-rich spring water. The facility features a single indoor bath, providing a simple yet authentic atmosphere. Though lacking in scenic views from the bath itself, the changing room offers a glimpse of the beautiful autumn foliage of Lake Poroto. Conveniently located near Shiraoi Station and attractions like the Porotokotan Ainu Village, it's an ideal spot for a relaxing day trip. Be aware that the water temperature is quite high, so those sensitive to heat should exercise caution.
