Komeiseki Onsen, also known as Ariiso no Yu, sits in Himi, Toyama prefecture, facing the Sea of Japan. Its sodium-chloride water reaches 42°C with a pH of 7.3, alongside an indoor bath, a rotenburo and a sauna.
Insider tip — Ariiso no Yu, the rocky shore spring, suits Himi perfectly — a fishing port on Toyama Bay famed for the finest buri yellowtail in Japan. Fishing boats return from the bay in winter laden with buri as snow falls on the Japanese Alps across the water, and this saline spring warms the fishermen after each haul.
