Ishidan no Sato Samata no Yu is a hot spring in Misato, Kumamoto prefecture, on the island of Kyushu. Its sodium-chloride water is offered at around 40°C. The site includes an indoor bath, an open-air outdoor bath and a sauna.
Insider tip — Misato-machi in central Kumamoto is celebrated for its Nihon Gokanosho — one of Japan's 100 most beautiful terraced rice field landscapes, where stone-stepped (ishidan) paddies climb the hillsides in cascading geometric patterns that are most spectacular when flooded in early May (the water reflects the sky) and golden in September harvest. The name 'Ishidan no Sato Samata no Yu' directly honors these famous stone terraces. Kumamoto's recovery from the devastating 2016 earthquake continues; the area's hot springs were comfort and respite for many displaced residents.
