Higashi Yoshino Onsen (Yahata Onsen), in Higashiyoshino, Nara Prefecture, offers iron-rich water at 40°C, with an indoor bath, an open-air outdoor bath (rotenburo) and a sauna.
Insider tip — Higashi Yoshino Onsen Yahata Onsen is located in the remote mountain village of Higashiyoshino, one of Japan's least populous municipalities, deep in the Yoshino range of Nara. The iron-rich water flows from ancient volcanic seams beneath forested peaks that inspired centuries of waka poetry. Reaching this onsen requires a scenic mountain drive through cedar and cypress groves. The profound quietude and mineral richness of the baths make it a pilgrimage destination for onsen connoisseurs.
