We dipped our legs into the River Oyunuma (“Oyunumagawa”) Natural Foot Bath in the onsen hot springs town of Noboribetsu (登別), Hokkaido (北海道). The Natural Footh Bath is about 400m in total length along the Oyunuma River, and it’s the perfect temperature to have a nice soak in a beautiful forest. The fresh gray sulfure spring flows from the nearby Oyunuma Hot Spring Pond (大湯沼)
