Shintoso Onsen is located in Kagoshima Prefecture, at the southern tip of Japan, a region of intense volcanic activity. Sodium-chloride thermal water rises at 42°C, feeding an indoor bath, an outdoor rotenburo, and a sauna.
Insider tip — Kagoshima is Japan's most volcanic city — live Sakurajima volcano is visible from virtually every street, regularly dusting the city in fine ash. Locals sweep ash from cars and pavements daily, then head to neighborhood sentos like Shintoso to wash it away in rich sodium-chloride waters. Kagoshima's 'sand bathing' (sunamushi) at Ibusuki and its shochu (sweet potato distilled spirit) culture complete the picture of Japan's 'Naples of the East'.
