Matsusaka Onsen (Kumano no Sato), in Matsusaka, Mie Prefecture, draws sodium-chloride water at 41°C. The bathhouse includes an indoor bath, an open-air outdoor bath (rotenburo) and a sauna.
Insider tip — Kumano no Sato spring serves Matsusaka City, the home of Matsusaka wagyu beef — considered by many Japanese connoisseurs the most marbled and flavourful beef in the world, even surpassing the famous Kobe variety. Matsusaka cattle are raised with exceptional care in the Mie mountain valleys, and the city is also the birthplace of the scholar Motoori Norinaga (1730-1801), whose 35-year project to decode the Kojiki ancient chronicles launched the revival of Japanese classical studies.
