About
Kaimi Onsen Unagi Yu (海味温泉 うなぎ湯) is a public bath run by the town of Nishikawa, inside its senior welfare center. Kaimi is read "Kaishu". The bathroom is plain and tidy: a large indoor bath and a few washing stations. The water is faintly cloudy with a sulfur smell, a little salty, and smooth on the skin, which is where the "eel" in the name comes from. It is a local bath, often nearly empty, with parking in front of the building.
