Jinzu Hot Spring

599. Jinzu Hot Spring, Kinokawa, Wakayama Onsen for 900 yen. Operating hours from 11:00 to 20:00 (closed Mon). They stamp the Wakayama 88 Onsen book. Inside there's an ad for a sauna with a window overlooking the forest. Bath photo from the internet matches reality. Indoor bath with clear water, has bubbles and single jet streams. The water felt slightly soapy on first immersion, but I didn't notice the effect after that. Temperature around 41.5°C. A bit stuffy inside. 12.06.2025
