Bath 1
Open-air baths provided in both Asanagi no Yu and Yunanagi no Yu, using an alkaline simple spring. The water from Nagato Yumoto Onsen, with a source temperature of 34.5°C, is heated for use, and it is known as a silky skin-beautifying bath with a proud 600-year history, the oldest in Yamaguchi Prefecture. It is an open space where you can bathe while gazing at the starry sky over Nagato and listening to the sounds of nature. It is said to help with neuralgia, muscle pain, joint pain, frozen shoulder, sensitivity to cold, and recovery from fatigue. The rocks in the open-air area also serve as resting spots for outdoor cooling breaks.
