Drinking SpringAbout
SeiRyuSo is an old-school ryokan by the river in Misasa onsen. Baths are split several ways: an indoor hall that swaps between men and women, gender-separated outdoor baths, Kajika-no-yu (かじかの湯) for men and Hotaru-no-yu (ほたるの湯) for women, and three reservable private baths, one of them with a river view, open to day visitors as well as overnight guests. A handful of rooms have their own open-air bath fed straight from the spring. The water is soft on the skin and faintly salty, and one of the outdoor baths is fine to drink from. Reviewers describe the place as unpretentious and not exactly new, but carefully kept, with a warm, old-fashioned feel to both the building and the staff.
