The charm of Otani Sanso is its hot springs.
Nagato Yumoto Onsen, where the inn is located, is the oldest hot spring in Yamaguchi, boasting 600 years of history.
In the Edo period (1603-1867), feudal lords used to visit this famous hot spring for therapeutic bathing.
The spring water is alkaline simple spring water.
With a pH of 9.67, it is highly alkaline and the water is lukewarm and thick.
It is a beautiful skin-cleansing hot spring with a high cleansing effect.
We especially recommend the guest rooms with open-air baths that were renovated in the summer of 2018.
Not only will you have the source all to yourself, but the view from the room is beautiful of the gently sloping mountain ridges.
The vivid gradation of greenery can be seen from anywhere in the room.
There are two 120 cm Simmons beds on Ryukyu tatami mats.
There is even a daybed, providing a perfect level of relaxation.
The calm, modern Japanese-style interior will ensure a quiet and high quality stay.
