Irumu no Yu
A natural hot spring using a mildly alkaline hypotonic cold mineral spring. With little irritation to the skin, it is loved as a beauty bath that can be enjoyed safely by everyone from children to the elderly. The outdoor bath area includes rock baths and pot baths, allowing you to spend a leisurely bathing time while gazing at the Fukagawa forest spreading out before you. The synergistic effect of forest bathing and the hot spring thoroughly soothes everyday fatigue.
