Shakochan Onsen, in Tsugaru, Aomori Prefecture, supplies thermal sodium-chloride water at 40°C. The site includes an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Tsugaru is the cultural crucible of two of Japan's most powerful traditions: Tsugaru-jamisen (津軽三味線) — the fiercely percussive, improvised shamisen lute style played at breathtaking speed unique to this region — and novelist Osamu Dazai (1909–1948, author of 'No Longer Human', one of Japan's best-selling novels). Shakochan Onsen's warm, affectionate name reflects Tsugaru's earthy, warm local character; Mt. Iwaki-san (1,625 m) watches over apple orchards and rice paddies.
