Hot Spring Sujiyu ONSEN Public Bath

Sujiyu ONSEN Public Bath
A peaceful hot spring town nestled among the Kuju Mountain Range, where history and tradition thrive.

Sujiyu Onsen is a hot spring in a gorge about 1,000 m above sea level, at the foot of Mt. Waita. This hot spring is said to have been in existence for more than 1,000 years, and provided visitors rest in mind and body for many centuries.

You can enjoy the charms unique to each of the four public baths: the Utase Daiyokujo (large bath with a cascading water stream), the Iwanyu bath (an outdoor bath encased in rock), the Yakushi-yu therapeutic bath (indoor Japanese cypress bath), and the Ikoi foot bath. Utase Daiyokujo features 18 streams falling from a 2 m height, and is also known as the best bath of its type in Japan. The location is popular with many travelers who come to soothe away fatigue from daily life or after climbing the Kuju Mountain Range, or to warm up during skiing season.
