Kinokawa, in the northern Wakayama Prefecture along the Kinokawa River that flows from the Koya highland, is a wide agricultural valley community known for exceptional fruit cultivation — the Kinokawa valley produces Japan's most celebrated mikan mandarin oranges, kaki persimmons, and Koya tofu whose delicate mountain water character reflects the pristine stream water flowing from the sacred Koyasan plateau. Wakayama Kinokawa Onsen draws on sodium and bicarbonate thermal waters from the geothermal resources of the Wakayama basin, providing restorative baths in a fruit-growing valley community where the exceptional Wakayama mandarin cultivation, the Kinokawa River cycling trail, and the access to the sacred Koyasan plateau via the Nankai Koya Line create an outstandingly agricultural and spiritually connected spa destination. The Kinokawa River valley mandarin and persimmon orchards whose fruit is harvested from October through winter, the Koyasan mountain temple complex with its extraordinary Okunoin cemetery accessible via the Koya Line, and the traditional Wakayama agricultural market culture make Kinokawa an appealingly fruitful and spiritually proximate spa destination in northern Wakayama.

Insider tip — Kinokawa city straddles the river of the same name as it winds through Wakayama's agricultural interior, and the onsen here taps bicarbonate-rich water from the ancient Kii crystalline basement. The surrounding persimmon orchards and strawberry farms of the Kinokawa valley create a distinctly rural atmosphere that contrasts sharply with nearby Osaka. The onsen is popular with pilgrims on the Kumano Kodo walking routes passing through the region.
