Joppari Onsen is located in Tsugaru, Aomori prefecture, at the northern tip of Honshū. Its sodium-chloride water reaches 41°C, supplying an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Joppari captures the essence of Tsugaru character — the term means stubbornly persistent in the local dialect, a quality that helped Aomori farmers endure brutal winters for generations. The spring and the word together honour a culture shaped by the novelist Osamu Dazai and the mournful Tsugaru shamisen tradition.
