Ryumonzan Onsen
Sampled at wellhead

Simple

Ryumonzan Onsen in Kinokawa is classified as an alkaline simple thermal spring — gentle and low in irritation. Weakly alkaline and soft on the skin, it sits close to Japan's beauty-water family, leaving a faintly slippery feel. Lightly mineralized overall, it is the kind of mild water well suited to a long, unhurried soak.

636. Dormy Inn Premium Wakayama, Wakayama Stayed overnight. Located five minutes on foot from the station. Got breakfast (buffet), but at 7:30 there was no way to get a seat — long line. Due to timing I didn't wait. Bath photos from the internet match. 1. Indoor zone. In the evening it was cozy — even a bit more interesting than usual for a Dormy Inn of this format. Breathing inside is fine. 1.1. Bath with clear water, temperature 40. 1.2. Sauna. 1.3. Cold bath. 2. Small outdoor bath with a TV on a closed balcony, no view. Breathing is good, but it doesn't feel like an outdoor bath at all. Clear water, temperature 41. A fairly standard Dormy, but given the selection of hotels with onsen in Wakayama City, I'd look at other places for an overnight stay. 02.11.2025
