Hakodate Nogi Onsen Nagomi, in the Nogi district of Hakodate, Hokkaido, offers sodium-chloride thermal water at 41°C, with an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Hakodate's Nogi district is a quiet residential area of this historically pivotal port city where Japan's Meiji Restoration reached its violent conclusion. The Battle of Hakodate (1869) — the final conflict between the new imperial government and Tokugawa loyalists — ended at nearby Goryokaku, Japan's only Western-style pentagonal star fort. Nagomi (harmony) onsen offers a calming sodium-chloride soak near the site of a city reconciled with its complex past, one of Hokkaido's most atmospheric historical experiences.
