Hokkaido Eniwa City
An exquisite spa with a rare moor spring and an automatic löyly system
"Eniwa Onsen Honoka" is a large spa resort in Eniwa, Hokkaido. A renovation in April 2025 made the sauna and relaxation spaces even better. Its biggest attraction is the chance to enjoy two kinds of natural hot spring water at the same time: the rare "moor spring," recognized as one of Hokkaido's heritage assets, and a highly heat-retaining "salt spring." The sauna features a high-temperature dry sauna with a newly installed automatic löyly system, where powerful heat and steam create a blissful sweating experience. The cold plunge bath, fed by continuously running groundwater filtered through black silica, has a mellow feel on the skin and is ideal for cooling down. With a full range of Iwaburo and a dining area, it is a place where you can enjoy beauty and relaxation all day long.
A rare natural hot spring containing plant-derived organic matter, recognized as one of Hokkaido's heritage assets. Its amber-colored water is known as a beauty bath and is characterized by its smooth, silky feel. It leaves the skin feeling soft and warms the body from the core. You can relax and enjoy this naturally nourishing water in the main indoor bath.
A natural sodium chloride spring. Because the salt coats the skin, it has excellent heat-retaining effects, and the warmth lingers long after you leave the bath. You can enjoy this thermal spring in the open-air bath and other areas, feeling Eniwa's refreshing breeze while easing the fatigue of everyday life.

The clean interior, filled with the scent of wood, is the perfect space to face yourself and find deep refreshment. After a thorough sweat, access to the adjoining cold plunge bath is smooth and easy.
A luxurious flow-through cold plunge bath using Eniwa's rich groundwater. With the renovation, the water is now passed through black silica ore, giving it a softer texture and a gentler feel on the skin. The crisp, cold water temperature quickly tightens a body warmed by the sauna, providing a refreshing cooldown. You can fully enjoy the clean, refreshing quality unique to groundwater and the high-grade water created by the power of the ore.
