Ikoi no Yakata, in Kasagi, Kyoto Prefecture, draws its sodium-chloride water at 41°C from a local natural spring. Indoor bath, outdoor rotenburo and sauna round out the offering.
Insider tip — Kasagi Ikoi no Yakata, the Kasagi angling retreat, serves the remote Kizu River confluence community of Kasagi-cho at the triple boundary of Kyoto, Nara, and Mie Prefectures where the Kizu River is famous for freshwater smelt fishing. Kasagi preserves the Kasagiyama Magaibutsu — three enormous Buddha images carved directly into the granite cliffs of Mount Kasagi, among the largest rock-carved Buddhas in the Kinki region dating to the Heian period — and the dramatic cliff-forest mountain above the spring has been a sacred site since the 9th century.
