Yumoto Onsenkan is located in Niimi, Okayama prefecture. Its sulfurous water reaches 44°C and feeds an indoor bath as well as an outdoor rotenburo, with a sauna.
Insider tip — Yumoto Onsenkan in Niimi draws sulfurous spring water from the mountainous interior of Okayama Prefecture, far from the coastal plains and closer in character to the volcanic springs of western Honshu. The pungent sulfur waters are reputed for skin-cleansing and antibacterial properties, and regular bathers claim visibly improved complexion after a series of soaks. The facility sits near the Kamo River headwaters where fishing and forest walks provide wholesome accompaniment to a thermal retreat. Autumn is particularly rewarding, with yellow and red momiji leaves reflected in the outdoor pool water.
