Highlights
Jet BathAbout
Tennen Onsen Hakodate Omori Noyu is the bathing floor of a hotel in Hakodate, open to day-use visitors as well as overnight guests. The water runs a distinct brown and tastes noticeably salty, and the open-air baths are fed straight from the source. Men's and women's sides each have their own rotenburo, and the women's side adds a small tsuboburo pot bath. Indoors the men's side has a bubble bath, and there is a dry sauna set fairly hot and a cold plunge pool that reviewers single out as unusually cold. A private family bath with heated (non-spring) water is also available.
