Shiriuchi Onsen (Utopia Warakuen) is a hot spring facility in Shiriuchi, at the southern tip of Hokkaido. Its sodium-chloride water flows at 42°C, pH 7.3. An indoor bath, an outdoor rotenburo bath and a sauna are available.
Insider tip — Utopia Warakuen, the garden of laughter and harmony, sits in Shiriuchi near the Hokkaido terminus of the Seikan Tunnel, the world longest undersea railway tunnel connecting the island to Honshu. The gentle saline spring and garden resort atmosphere contrast pleasantly with the dramatic engineering feat beneath the Tsugaru Strait nearby.
