Another Eniwa bathhouse, Eniwa Onsen Honoka also draws sodium-chloride water at 42°C with a pH of 7.3, offering an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Honoka, meaning faint and gentle, describes both the soft light filtering through the birch forest here and the subtly saline water of this Eniwa spring. The facility is popular with Sapporo day-trippers seeking a quieter alternative to the busier resort onsens further south.
