Agi Onsen, known as Ajisai no Sato, is located in the city of Inabe, Mie Prefecture. Its sodium-chloride thermal water is kept around 40°C (pH 7.3), with an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Inabe city's Nunome Reservoir area is Japan's most celebrated hydrangea landscape — thousands of hydrangeas in deep blue, purple, and white cascade around the lake in late June, drawing visitors from across the Kinki region to the Inabe Agricultural Park. 'Ajisai no Sato' (Hydrangea Village) perfectly captures this floral identity. Inabe's Suzuka Mountains provide excellent hiking trails; the Suzuka Circuit racing track is 20 km south. A hydrangea morning, mountain hiking afternoon, and warm onsen soak as the petals fade is the ideal Inabe day.
