Shio Sakura no Sato Onsen (Kofun no Yu), in Hodatsushimizu, Ishikawa Prefecture, offers sodium-chloride water at 41°C, with an indoor bath, an outdoor bath (rotenburo) and a sauna.
Insider tip — Kofun no Yu, the ancient burial mound spring, serves Hodatsushimizu in the Kahoku coastal plain of Ishikawa where over one hundred Kofun period (3rd-7th century) burial mounds are concentrated in the farmland between the Hodatsu hills and Kahoku Lagoon. Excavations of these mounds have revealed bronze mirrors, iron swords, and gilt horse trappings indicating the wealth of local clan leaders who controlled the sea trade routes through the Noto Peninsula — a documentary record in earth and bronze of the ancient politics of the Japan Sea coast.
