ONSEN
Sansien has no public bath. Three private hot springs — Yama-no-yu, En-no-yu, and Hoshi-no-yu — are yours at any hour, with no time limit.
The scent of hinoki fills this indoor bath. Watch the moss garden while the hot water does its work. Spacious enough for 2–4.
A stone outdoor bath set within the inn's garden. Cherry blossom in spring, maple in autumn — the seasons frame the view.
A covered half-outdoor bath — open to the night air but sheltered from rain. Lie back and watch the stars through the open side.

SOURCE
Classified as a weak salt spring with a faint salty taste. The mineral coating on skin keeps you warm long after stepping out. No dilution, no circulation — straight from the source.
Yama-no-yu is indoor hinoki cypress. En-no-yu is stone, outdoors in the garden. Hoshi-no-yu is covered, half-open to the night. Same water, three entirely different experiences.
Morning, evening, night — each visit feels different. That's the pleasure of having them all to yourself.
