Sukayu Onsen is an onsen in the Hakkōda Mountains in the city of Aomori, Aomori Prefecture in Japan. It is known for its "Sen-nin-buro" or "Bath of a thousand bathers", a large mixed gender public bath.
Insider tip — The Hiba Sennin-buro is the largest traditional onsen bath in Japan. Come at dawn when the steam and light create an almost mystical atmosphere.
