Iwahana Onsen is located in Kumano, Wakayama Prefecture, a Japanese region known for its hot springs and pilgrimage trails. This thermal bath offers both indoor and outdoor (rotenburo) pools plus a sauna, with water at a slightly alkaline pH of 7.3.
Insider tip — Iwahana Onsen — natural hot spring in the Kumano/Kii Peninsula area of Wakayama prefecture, very close to the sacred Kumano Kodo pilgrimage trails. The Kii Peninsula is Japan's geothermally active spiritual heartland. Soak near the same rivers that generations of pilgrims have walked beside on their way to the Kumano Grand Shrines.
